Beardies UV Light Flickering? Urgent!?

Hi, Turn it off and purchase a new one. Please be aware just because a light is. On does not mean your UV light is working! They run out after 5-6 months, so although the light appears to be working all it is, light and no UV rays are available. Your bulb has unfortunately meet its end.

1. Are there energy efficient UV light bulbs for reptiles?

it extremely is a reasonably super enclosure for a ball python. Enclosures that super are no longer ordinary to maintain heat now and back. Ball pythons do no longer require UV. family bulbs are no longer cautioned to warmth snakes. it extremely is theory that some snakes do acquire advantages from exposure to small quantities of UV each so often. in case you are utilising a warmth pad and heat a lamp and nevertheless no longer accomplishing the spectacular temperatures on your ball python, it extremely is recommended to establish a 2nd lamp. during the day, load each and each of your lamps with a seventy 5 watt reptile day bulb and, at evening, stick in 60 watt crimson reptile evening bulbs in them. perhaps this could help. i am kinda leary approximately recommending yet another warmth pad on your subject because of the fact, only this previous week, we had a favorite snake farm here in Texas and, on the threshold of the place I stay, seize on hearth because of the fact of defective warmth pads. It replaced into the snake farm that replaced into featured on Discovery Channel's" Dirtiest Jobs"

2. is the mineral topaz associated with any gods or goddesses?

I personally do not much care for topaz. I am a ruby fan. I have a ruby ring made from a 14x10 lab ruby cabochon and a 92.5% silver setting that allows almost all the curved side of the cabochon to be seen. Reddish points of light play around inside the stone very nicely as I turn my hand or wiggle my fingers. And rubies fluoresce bright red in UV light. Topaz would not be anywhere near this good.

3. How can I make invisible ink that is visible under UV light?

These are readily available as sales products to the textile and paper making industries under the generic description of FWA - fluorescent whitening agents or OBA - optical brightening agents. I am sure that if you can find a local sales office of one of the international chemical sales companies such as CIBA they will probably give you a small sample. Otherwise enter Fluorescent Whitening Agents into Google and you will find many references. Many liquid and powder detergents ahve these in their formulas, so it might even work if you make an "ink" out of a solution of one of these. Try it and see,

4. How long should a UV Light for fish be turned on?

1. UV lights need to have a slow water flow rate through them or they do not do anything at all 2. bulbs need to be replaced about every 6 months, but at least yearly because they stop producing UV 3. you can run them less than all day to save energy 4. cleaning the inside tube is essential to proper operation, but be very careful it's way fragile and expensive crystal, not cheap glass. 5. properly prefiltering the water of fine debris is also essential to it's working

5. can you see germs with a blue light?

eelrahc, there is some truth to your statement. Germs that you cannot see with a blue light without a microscope include bacteria and viruses. But some germs, called fungi, can be detected with an ultraviolet (UV) black light. The most common way to diagnose fungal infections of the skin used to be a Wood's lamp, more commonly called a black light today. Not all fungi fluoresce in ultraviolet light, but many species do. Over time, these easy-to-spot species have been replaced by species that do not fluoresce, the major exception being ringworm, of which about half the species fluoresce in UV light. If a ringworm or another fluorescent fungus is present, the site should glow bright green

6. Why can't I reproduce a back-focus problem at home?

Here is a different thought, less likely: the above photographs are both water fowl. When they are hit by light reflected from the water, much of the light may be polarised. Phase detection autofocus does not work well with linearly polarised light. It that is the problem, using a circular(!) polariser for that kind of photograph should help. Actually, you would just need the part of the polariser distinguishing it from a linear polariser, the so-called quarter-wave plate, but those are not really available separately.This is a real stretch, though: I should be rather surprised if this bears any relation to your problem. If it does, switching the autofocus method to contrast-based focus should help, no idea whether this is possible.Checking the Wikipedia page I read:which does not look promising. Maybe a web search can turn up more?Another thought with regard to possible differences: maybe the autofocus sensor is sensitive to UV light (on a DSLR, the UV protected sensor and the focusing mechanism typically are separate since focus needs to work outside of life view)? Since UV light tends to be refracted stronger than visible light (which can cause purple fringing for near-UV light), if the focus sensor reacts to it, it would tend to back-focus. Is your lens somewhat prone to purple fringing in wide angle scenes backlit by sun- or skylight? Indoors lighting tends to contain almost no UV light. If that is related to your problem, a good UV filter might be not as useless as normal for digital cameras

Polystyrene Dopped with Schiff Base to Reduce Outdoor Plastic Degradation for Sustainable Environmen
Polystyrene Dopped with Schiff Base to Reduce Outdoor Plastic Degradation for Sustainable Environmen
There is an increase demand for materials that can be reused or last for longer time to achieve a more sustainable environment, not only in terms of chemical and energy required to produce these products but also the energy required to dispose these materials. In this study, a Schiff base was used as anti-aging compound to reduce the effect of UV light on polystyrene. Schiff base compound 1 was dispersed within polystyrene matrix. The obtained materials were subjected to an accelerated aging process under continuous UV radiation. The effectiveness of the polystyrene film containing Schiff base was compared to a polystyrene (blank) film. Weight loss, scanning electron microscopy, and FTIR spectroscopy tests were performed to confirm that the new polymers had more resistant to UV light.1. How often should I sanitize my phone using UV light?I do not think you need to do that2. Where can I buy a UV pass filter?There are a couple of options.One common name for that will be a "short pass" filter. You can find these in scientific supply and optics companies. Ultraviolet is typically defined as wavelengths of light below 400nm. Keep in mind that the glass used in most lenses will block UV light wavelengths much below 350 nm. So if you're interested in using this for photography, you're going to have a very narrow window of UV light you can "see" with the camera, unless you go to a special (and very expensive) lens made of quartz glass.Or a pinhole camera, of course. Though that's getting into other problems, as you'll need a very fine pinhole to deliver a clear(ish) image, and that's likely to get into diffraction issues with your camera sensor if you go too small. ResourcesInfrared & UV Photography FiltersOptical Bandpass Filters - Bandpass Filters - Bandpass FilterShortpass Filters at Omega OpticalUltraviolet Transmitting, Visible Absorbing FiltersUV FiltersWhere can I buy a UV pass filter?3. Will enough UV light get through acrylic perspex for my bearded dragon?Nothing will get through. Any solid will filter out UVA & UVB. Use a steel wire top or steel mesh (screen door)4. In replacement of a UV light, can I use a black light for my bearded dragon? ?As said, you need those UVB bulbs. Now, those chain stores overprice everything! under Supplies5. Do i keep the UV light for my bearded dragon on 24/7??"Proper lighting is also very important to the well-being of a Bearded Dragon. A good split of day/night is 14/10. This can easily be regulated by a timer, which can be found at almost any hardware store. ((not only is it better for the Dragon... its much easier on the caregiver. :)) A basking spot is also a must for a Beardie. The Dragons body temperatures are important for digestion and fighting off illness. A low watt bulb, placed in a reflector dome at one end of the cage, will concentrate the bulbs heat to that one side of the cage. The top basking area on one side of the cage (closest to the light) should peek between 100 - 105 degrees for adults and 100 - 110 for babies - with the ambient cage temperature on the other side of the cage being significantly cooler - approximately 80-85 degrees. This basking temperature may seem high, but these temperatures are common of the ground surface when air temperatures are over 85 degrees. Remember though, this is a peek temperature and not a constant temperature. The trick is to slowly bring the temperature of the basking area up, allow it to level off for a short period of time and then drop slowly once again. (Yes, this can be tricky... but that is where cage accessories come in handy.) The nighttime temperature of your cage can drop into the 60's without worry. If your house gets cooler than that, you may need to invest in a red bulb for nighttime temperature maintenance. This will emit the heat needed to keep the temperature up, but not the light that will interrupt the dragons sleep pattern. WARNING - Do not use an electrical reptile heat rock or heating pad as a heat source for your Bearded Dragons. These products have the potential to fatally burn the dragon's belly, as many lizards do not feel a 'localized' temperature... but an overall body temperature. (See Thermal Burns below) The need for a full spectrum florescent reptile light is among those topics being disputed between Hobbyists at the moment. Dragons DO need a source of UVB light to naturally produce vitamin D3, (which helps to absorb calcium) and without a steady supply of it, are more subject to complications. This can be obtained by a bulb or by subjecting your Dragon to natural sunlight for a period of time each day. Many people think that by placing the vivarium near a window and allowing the reptile to bask in the sun will help. This is not so. Normal plate glass as used in windows and vivariums will actually filter out the ultra-violet rays that are required to synthesize natural vitamin D3. If choosing to use a full spectrum light, the bulb should be within 6-10 inches of the basking area, so they can absorb the UV-A and UV-B to manufacture their vitamin D3 for bone formation. These bulbs need to be replaced after 6 months time. Once again, it is not vital AS LONG AS there is proper supplementation in their diet and enough light intensity. We feel UVB indoor lights are not needed if dragons are fed a proper diet; and supplemented with Vitamin D3. A calcium/D3 supplement, like RepCal can be used in place of the UVB bulb. The dragon still received its needed Vitamin D3, but instead of producing it itself, it is given dietarily."
I Want to Understand the Link Between Lupus and Photosensitivity. and How Or Why It May Cause a Flar
I Want to Understand the Link Between Lupus and Photosensitivity. and How Or Why It May Cause a Flar
People who are affected with systemic lupus erythematosus (SLE); esp those affected with cutaneous lupus often discover that they are highly photosensitive, or sensitive to sunlight. Reasons why lupus patients are more susceptible to sunlight ARE STILL poorly understood. It is suspected, however, that UV light causes skin cells to express particular proteins on their surface, attracting anitbodies. The antibodies in turn attract white blood cells, which attack skin cells, which leads to inflammation. Apoptosis, or cell death, normally occurs at this point, but it is amplified in lupus patients, which increases inflammation. Either way, this sensitivity results in rashes and other skin conditions like sunburn. In SLE, this photosensitivity can also TRIGGER flares, including joint pain and fatigue. If left unchecked, this condition could lead to skin cancer. Certain medications, like tetracycline antibiotics (often used to fight acne), can increase a lupus patient's photosensitivity risk. Thus, lupus patients are instructed to take care of their skin and stay out of the sun But how do you stay out of the sun when sun is all around? Here are some simple tips: Avoid the Midday Sun: The intensity of UV light at this time of day is usually at its peak. It is suggested that avoiding noonday sun can eliminate the need for other tactics. Some literature suggests avoiding the sun between 10 a.m. to 4 p.m., if possible. Wear the Correct Clothing: If you are going to be out in the middle of a summer day, leave the tank top and shorts at home. Broad-brimmed hats and tightly-woven, loose-fitting clothing with long sleeves and long pants are all the rage for those affected with lupus. Use Sunscreens: After sun avoidance and adequate clothing, application of sunscreen is your next line of defense. Sunscreens absorb or scatter UV light, depending on what chemicals are in your concoction. Use the correct amount. A light coating wo not due. To get the full protection factor of your sunscreen, you should use at least an ounce of sunscreen if you stand about 5 foot, 8 inches tall. And wear sunscreen year-round, not just the summer. =Turn Off Other Sources of UV Light: This includes fluorescent tube lights, halogen bulbs, and, according to the British Association of Dermatologists, environmentally friendly light bulbs (compact fluorescent tubes). And keep the cover of the office copier closed. Take Your Medicine as Directed: If you are taking a medication for your skin condition, make sure you take it as directed by your doctor. =And Know What You are Taking: As stated above, some drugs can worsen your skin condition, including drugs used to treat lupus, like nonsteroidal anti-inflammatory drugs. Watch Your Make-Up: Stick to brands that are also UV protectors, and are hypoallergenic People with lupus should realize that a tan is not necessarily healthy. The sun "is their enemy." A sensible lifestyle includes minimizing excessive UV exposure and using photoprotection. Outside activities should be completed before 10:00 AM and after 4:00 PM when the UV rays are less intense. People with lupus should not sunbathe or use tanning booths. Those who work outdoors may need to change occupations Common sense should prevail. People lupus should be neither a "mole" nor a lifeguard. Through experience, each individual's skin type and degree of photosensitivity can be learned. Even if a person is not photosensitive, it is wise to be careful about sun exposure. By taking appropriate precautions and using common sense, individuals with lupus can achieve photoprotection. It's great that you are a concerned and loving son. Your mother/father is very lucky to have you.1. Can a color-blind person imagine colors they can't see? (concerns UV light)?I believe no. The only reason we can imagine any color in our heads is because we already know color. If we did not know color to begin with how could we imagine color, it would literally be like consciously creating life before your eyes or having something pop up out of nothing into reality. The only reason why we can imagine red, and variations of res is because we 'know' red, if we didnt know red existed then even a variation of red could not exist. Between white and black, light and dark, infinity colors can exist, colors we havent seen yet. Just like red and yellow were possibilities between white and black, colors not seen yet should also be possibilities.2. my BD's UV light keeps cutting out?If you are handy, you can try replacing the fuse. It's a small cylinder about the size of the end of your thumb, with two pegs sticking out. If you want a quick fix, just replace the light - not just the bulb, the whole light.3.

What Are the Functions and Advantages of Uv Light?
What Are the Functions and Advantages of Uv Light?
Most people know the sun can hurt our eyes but are less clear on whether to worry about other bright lights, like computer screens. In short, these screens are far less damaging than the sun. This is because screens are not as bright as the sun, and newer screens do not generally produce UV rays, the most damaging kind of light the sun produces. Instead, the most important light to consider that screens produce is short wavelength, high-energy blue light. (Learn More) In the short term, blue light is mostly associated with potentially causing eye strain. This usually is not serious and can mostly be solved by habitually looking away from your screen on occasion and practicing some basic techniques to reduce the strain. In the long term, some studies have suggested the blue light from screens can damage retinal cells, leading to problems like age-related macular degeneration. The extent of this issue is not fully understood, but it is notably not serious enough to suddenly avoid all use of screens. (Learn More) Vision experts generally do not consider screens as a source of permanent vision damage, even if extended use can cause eye irritation. If you only look at screens for a few hours a day and do not experience any vision issues, you probably do not need to worry. The biggest thing to consider when it comes to screens is if and how much they may damage our eyes in the long term. There is not yet a fully clear answer, so more research needs to be done. The accepted view is that the blue light from screens is not a major cause of long-term vision issues, though excessive use should be avoided. (Learn More) Many people are understandably under the impression that any bright light aimed at our eyes can cause permanent damage. After all, the sun is one of the brightest things we encounter on a regular basis, and it is well understood that it can damage our eyes. In some respects, it makes sense to think that even light sources that are not as bright, such as computers and smartphone screens, might damage our eyes too, given enough time. This is somewhat true, although not to the degree many assume. The sun produces a wide spectrum of light rays. Its white color comes from the fact that it is producing red, orange, yellow, green, blue, indigo, and violet light all at once. Importantly, it also produces ultraviolet (UV) rays, which are invisible but can readily cause permanent damage if you are exposed to them for lengthy periods of time. While skin damage from UV light is often discussed, the sun's rays can also damage the eyes. Old cathode ray screens (now almost completely obsolete and no longer used by the bulk of people) actually produced a tiny amount of UV rays when in use, but newer screens do not. The most troublesome light our modern devices (ranging from light bulbs to tablets) tend to produce is blue light. This type of light has short wavelengths and relatively high amounts of energy. While blue light is not extremely dangerous and comes in far higher quantities from the sun, there is at least one study suggesting that long-term exposure to blue light through our devices may cause at least some eye harm. In the short term, staring at screens for a long time is known to sometimes cause computer vision syndrome, or digital eye strain. While not serious, this condition can still be irritating and even detrimental to one's work. It can potentially cause: Digital eye strain is not just caused by exposure to blue light; it's caused by a combination of factors. The first factor is simply the length of exposure. The average American worker spends at least seven hours in front of a screen, and some people spend significantly more time than staring at screens. Compounding the issue is the fact that many people are unfortunately in the habit of maintaining bad posture while staring at screens. Take a look at one of the many charts and articles online discussing how to properly sit at a computer. Posture and proper distancing from your computer can really help to reduce eye strain. While you may not notice an immediate difference, you will feel the effects of good posture and ergonomics over time. Try to light your workspace (or wherever you will be looking at a screen) properly, so the light level in the room is roughly equal to how much light your screen will be producing. Contrasting levels of light, such as being in a dark room while looking at a bright screen, can strain the eyes faster. Practice the 20-20-20 rule. This simple rule can help with eye strain. All you need to do is take a break every 20 minutes or so to stare at an object about 20 feet away for at least 20 seconds. This helps to give your eyes a break from focusing on a bright screen that is close to you. Make this rule a habit, and you will feel the difference in your eyes over time. While computer vision syndrome or digital eye strain is almost always temporary, some individuals start to experience lingering problems if they continually experience it and do nothing to mitigate their symptoms. If you really struggle with this problem, talk to an eye doctor about the best solution for you to avoid more serious eye problems in the future. Screens may be causing a subtler and less understood long-term problem. This was brought to light in studies that suggested sustained exposure to blue light could lead to impaired retinal cells. This has been linked to problems like age-related macular degeneration (AMD), which can cause blurred vision. There is no cure for AMD, but the condition can be managed. There are some things you can do to protect your eyes from blue light. The most obvious is simply reduce screen time. Some evidence suggests children's eyes absorb more blue light than adults' eyes. Children should have less screen time than adults. There are filters and special glasses that are designed to reduce how much blue light is hitting your eyes. Many of these filters can also help with eye strain, as they reduce how bright your screen is compared to the rest of the room. You can benefit from wearing these glasses or using the filters for at least a few hours of your time in front of a screen each day. How Concerned Should You Be? If you do not notice much eye strain or other issues after extended computer or smartphone use, you probably do not have anything to worry about. Staring at a screen is certainly nothing like staring at the sun. If you only use screens for a few hours a day, it's unlikely you will ever experience any screen-related vision problems. The biggest concern is just how much blue light may be contributing to age-related macular degeneration. Macular degeneration is not curable and can lead to blindness, but it also is not life-threatening and can be treated. While the condition wo not go away, it can be managed so it progresses slowly. Most people with AMD are able to manage its progression, so they maintain some level of good vision for many years. Blue light is not the sole cause of age-related macular degeneration. It is caused by a combination of many factors. If you believe you are at risk of AMD, it can be helpful to limit your screen time. An exact number on the amount of ideal screen time is tough to pinpoint. Most vision experts are not too concerned that screens cause much permanent damage (if any damage at all), but in some cases, screens can cause discomfort or potentially more serious problems. Ultimately, it is not healthy to stare at a screen for hours on end. Excessive screen time brings various other concerns, other than just vision-related problems. Extended use of screens has been linked to various health issues, including obesity and insomnia. Overall, limiting your screen time to a few hours a day and practicing the 20-20-20 rule should be enough to avoid any major vision problems related to screen time. Proper Sitting Posture at a Computer (According to Experts). (April 2019). Ergonomic Trends. What Is Macular Degeneration? (May 2019). American Academy of Ophthalmology.1. What liquids will glow under UV light in a color other than flourescent blue?Fluorescent components % to take up ultraviolet gentle via fact it has a short wavelength. whilst ultraviolet gentle, or blacklight, shines on an merchandise or floor that contains fluorescence, the ultraviolet gentle is absorbed and re-emitted in an prolonged wavelength, transforming into seen. usually any shade with an quantity of fluorescence or phosphorescence will react with a blacklight, regardless of if reds are very low on the spectrum and maximum do no longer react nicely to blacklight even whilst dealt with chemically to extend ultraviolet visibility; an exception to this rule is blood, which like different consumer-friendly actual fluids, contains fluorescence and glows brightly below blacklight.2. difference between blacklight and uv light?They are the same.3. In replacement of a UV light, can I use a black light for my bearded dragon? ?no becasue the black light doesnt have the same nutrients in it that the regular red or the uv lights have. you can get the lights at a pet store for only 5 bucks. they have a picture of a bearded dragon on them. they shouldnt be too expensive but dont do a black light i mean maybe for at night but not for a overall light. its not healthy
Is the Uv Light Used in the Dentist Bad for Your Eyes If You Look at It for a Couple of Seconds...?
UV light is bad but the dentist do not use UV light for any procedures. It is plane blue light used for light curing composit fillings1. is there a way to create UV light?If you plan on surviving a nuclear war, do not count on growing food in your basement. The soil wo not last long enough anyway. Just stock up on non-perishable food. The best kind is large economy-sized bags of dry dog food. It lasts almost forever and the nutrient value is very close to what humans require. Most likely, however, if you live near a large city, you will suffocate instead of starve as all the oxygen is used up because of the blast2. How quickly does a supernova heat up/expand?Ricky, it is very rapid. The core collapse and initial neutrino burst takes seconds to tens of seconds. We do not normally think about neutrino interactions, but so many are released that even this might be a problem for a nearby habitable planet. It then takes a few hours for the shockwave from the core collapse and bounce to make it out to the surface, accompanied by an intense flash of UV light that would likely sterilise anything in its planetary system. The outer layers of the exploding star are hurled out at around 1000 km/s, so could travel an astronomical unit in a day or so.The supernova continues to become more luminous for about a week thereafter, increasing in luminosity, from what must have already been enormous (thousands of solar luminosities) by another factor of $10^5$. The equilibrium temperature of any planet scales roughly as $L^1/4$, so temperatures would rise by more than an order of magnitude in a week.3. Do you have to use a UV light to dry Shellac ?Shellac Light4. Why is UV-light blue/violet if it is invisible to the human eye?UV light IS invisible to the human eye. You may be interpreting light from so called black lights as only UV. While black lights do emit some UV you are seeing the far end of the visible spectrum which is a deep violet, just at the threshold of human vision. -NH5. Can my aquarium's UV light damage my eyes?usually direct staring would cause problems - with any light. If going to sleep, best to turn off the light as any light going through the eyelid can disrupt your sleep (restlessness for example). Best to move the tank, or where the bed is, just so to shield your eyes from the direct light.6. leopard geckos uv light question?Just do it for a week no more you may harm your lgecko though7. What is ultra violent (UV) light?Uv rays are the rays that are not visible and have a high energy. Electro megnatic radiation having wavelength shorter than voilet. It does not mean that black uv colour actually it is the submission of all the visible colour.8. Do fluorescent light bulbs contain UV?All Fluorescent lights work by producing UV light. The phosphor coating of the glass absorbs this and emits visible light. They do not "contain" UV light. It is only produced when the light is on. The reason you want some UV radiation for your tank is to act as an anti microbial. Fluorescent unless designed for that do not emit enough to do much good.9. What UV Dye's are used for A/C systems that you DO NOT need a UV light to see the leak?I do not know of any A/C leak dyes that are used any other way than with a UV light. UV lights are cheap and readily available so I do not know what the issue is with using one. You put the dye in using a dye injector on the suction port. The dye has to circulate around the system to work, which means the system has to be charged and operational. So rather than wasting refrigerant and harming the ozone layer, a much better method would be to leak test using nitrogen. Put about 100 psi of nitrogen in the system and check for leaks using soap. If it's a big leak you can listen for hissing. Since it sounds like you have not done this before and you do not have the proper equipment, I would highly recommend you bring it to an EPA certified A/C tech.
Research and Review: Using UV Light to Disinfect
There is much to be learned when it comes to using light in new and innovative ways. It's not yet sufficient to say that UV or 405nm light is successful and a best practice, but it would likewise be inappropriate to discount studies that show their effectiveness. As more studies are concluded and new information surfaces it's vital that modern designers stay vigilant and informed to be able to best make decisions about the future of the spaces they create.How to wire or add the motion light at porch?Try using a photo sensing socket adapter which detects the presence of light and during dusk the light comes on. Very cheap and sold at most all local hardware stores. A motion adapter probably wo not work as expected unless your light bulb is in range of you while your walking. You could try then take it back if it did not work. Make sure to turn off the switch first before applying adapters and stick with your typical Edison base bulbs as fluorescents can cause problems with solid state devices.If a massless observer is going at the speed of light, what speed will it measure of a light beam going parallel to it? [duplicate]what speed will it measure of a light beam going parallel to it ?Suppose an entity $A$ has speed $c$ in an inertial frame of reference (IFR) then, according to SR, $A$ has speed $c$ in all IFRs, i.e., there is no IFR in which $A$ is at rest.That is, there are no rulers and there are no clocks at rest with respect to $A$ with which to measure distance and time or change of distance with time.The speed of light is always constant so it should be considered as an inertial frame of referenceThere is no IRF with relative speed $c$, there is no IRF in which a photon is at rest, there is no inertial frame of reference for a photon.UVB Lighting. Please Help.?yes they work very well. you can find them at almost any pet store. they give off light like it's the real sun i think they are the best kind of light for thatwhich type of visible light has the most energy?define "energy" well, since a laser is a "type" of light and violet is a color of light.... the Type with the most energy would be a laserBest Underwater Boat LightsThere is no denying that a nice arrangement of underwater boat lights make for a very classy look. That colored underwater glow adds a level of sophistication that is unmatched by lighting above the waterline. Today's best underwater boat lights have come a long way from the marine lights of old. Modern underwater lights provide a variety of color availability as well as effects like crossfade, dim control, and even strobe from the comfort of your deck chair. With marine grade housing and hardware, you can know your investment is built to last. The trouble comes with sorting through all the different models available. Bargain basement underwater lights are not going to last the summers of watersports and stand the test of time. So which models are reliable and preferred in the vanguard of boating circles? We are here to help with that. If you can not tell already, we are big boating fans here at Rowing Inc and we want to help you get set up with underwater boat lighting that you will love for years to come. With that said, there are some important details to consider in order to get the best underwater lighting system so you can enjoy your lights and avoid unexpected failure, replacement, or leaks. The list of features below is meant to help you with making an informed decision when you are considering which boat lights will meet your preferences. We've also included a comparison table of 5 of the most popular and reliable underwater boat lights, just to make the details a little easier to digest. If you are searching for the best underwater boat lights, we are sure this guide can point you in the right direction. Brightness - Like many other lighting solutions today, underwater boat lights are rated in lumens. You might be more familiar with watts as a unit of measurement, but lumens are a more accurate measure of the amount of light produced by a given source. High quality underwater boat lights are often the most bright as well as being dimmable. We really like this option because you can always dim your underwater lighting if it seems too bright, as opposed to a lower-quality light that wo not produce enough light for your needs. Color - When it comes to underwater boat lights, blue and white are by far the most popular options. Green and red are also common options. We really like the combination lighting option available as well, which often come in blue/white or blue/green, and can be changed from one color option to the other. These combinations effectively provide you with two different underwater lights in one unit. Effects -Along with providing color changes, high quality under water boat lights also provide some limited effects. Thankfully we are not talking about mimicking a Pink Floyd concert here, but there are some neat and helpful aspects to the effects available. Setting up a coordinated color scheme is that much more effective when run in combination with options like strobe, cross fade, and dimmable lighting as well. Marine Grade - This is feature really cannot be over-emphasized. Be careful with inexpensive bargain lighting solutions. The alloys used in the housing of the lights and hardware is sometimes questionable and can cause premature failure. The last thing you want is a dead underwater light that requires pulling your boat from the water in order to repair, or more likely, replace. Drilling - Nearly all underwater boat lights of any quality are going to require drilling a hole in the hull around 1/2 inch in size which will allow for the wiring to pass through. After applying some marine sealant, the housing will also require fasteners that fixate the underwater light to the hull. One of the highest-quality underwater marine lights on the market at the moment, Lumitec's SeaBlazeX underwater boat light is a popular product for night fishing. Offering incredibly powerful lighting, and a selection of colors, these lights are among the brightest available. The Lumitec SeaBlaze range is renowned for its quality and performance. Lumitec SeaBlazeX lights come in a range of colors, including white, green, blue and dual-tone white and blue, and with in-built controls, you can flick between colors or change modes at the touch of a button with no need for external controllers. The power of these underwater LED lights is undoubtedly a selling point. Lighting up to 4,000 lumens with a range of settings to switch between strobe and cross-fade, you can customize your lights to suit all scenarios and environments. The lights are powered by 12-24 volt DC and they are contained within sleek, marine-grade bronze alloy casing. The marine-grade housing is designed to offer protection from the elements and enhance durability and longevity.

How Do You Know If a Light Is a UV Light?
Put something bleached white under it (such as a sheet of printer paper or your socks). If your light is emitting in the UV spectrum, the paper will fluoresce, appearing to glow a purplish or bluish color. This effect is most prominent in the dark. Also, I've noticed that UV lamps tend to make peanut butter look greenish when it is held close. Maybe that's a good test too.1. What makes UV light, in particular, harmful to your body? What exactly is the difference between it and the "normal" light?By "normal light" I assume you mean visible light. UV light is made of photons that carry much more energy than visible light. You can think of visible light hitting your skin as little foam balls bouncing off of your skin. UV light is more like steel balls pelting your skin. Because UV photons carry more energy, they can do more damage when they hit you. Specifically, UV light is really good at pentrating your skin and damaging your DNA.2. What do I do if I dont have a UV light for my turtles?a different in step with threat. Turtles choose nutrition D to stay healthful. they are in a position to get it from a UVB bulb, from image voltaic that has no longer gone by using glass, or from their weight loss plan (meals like liver)3. How do vampires react to passive UV light sources?Vampires are fictional creatures. In the stories I have read some are sensitive to garlic, some to holy water (and were mocked by non christian influenced vampires for this), some to light, some to silver, some to wooden stakes. To cut it short: it is your story, you are free to set up any reaction to UV light that suits your plot needs.By the way, being non living creatures they would be "cold", so IR vision would not spot them from the background as it does with living beings.4. In replacement of a UV light, can I use a black light for my bearded dragon? ?This Site Might Help You. RE: In replacement of a UV light, can I use a black light for my bearded dragon? ? I am looking at the costs of UV lights and they are outrageous. From the research I've done on blacklights it is basically the same thing.. I'm assuming. If I can't use a blacklight what are some cheaper ways to go? Thanks so much, and please only answers from people who know what they...5. When a hot flame is white is it just made of all colors or just of UV-light or an other wavelength?What is Physics Good For?If it looks white then it is made up of a spectrum of all frequencies. Like much of physics colour is in the eye of the beholder, in this case literally;)The image above shows what 'black body' radiation looks like as a function of temperature. There is more beyond white, blue for example, but when I attempted to find a suitable image to display it Google produced inappropriate images;)When a hot flame is white is it just made of all colors or just of UV-light or an other wavelength?.6. UV light for Ball Pythons?no inderect sunlight will not work. I suggest getting a uva uvb light7. If UV light is not visible, then why are black lights purple?It may be possible to make one that produces pure UV but it would be dangerous. How would you know when it is ON? How would you avoid looking at a bright UV source that might be dangerous? So all UV lights also produce some visible light. It would have to be mandated for safety reasons even if we did not otherwise have to do it.8. Ethidium bromide and mutagenesis on cloningPurified DNA contains negligible amounts of ethidium bromide. PCR and gel clean-up kits remove it quite well. There is, though, a risk of mutation from the fact that you are visualizing the gel in UV light with ethidium bromide. The risk of mutation from UV is minimized by exposing the gel as little as possible, and by using "preparative" transilluminators that come with a low-light setting for cloning purposes. If you work well and quickly, the chance of mutagenesis is not higher than the chance of a polymerase incorporating the wrong nucleotide
So, I Just Got a Hot Tub & I Want to Look into Using Something Besides Chemicals. Any Idea's?
Congrads on your new hot tub purchase! Now, do realize you are always going to have to use a sanitizer, besides balancing your water's pH, Alkalinity and Calcium Hardness level. With that said you can cut down on the amount of Bromine or chlorine you are going to use. Personally in my hot tub I use a Corona Discharge gas plasma ozonator. It creates ozone that destroys bacteria. I use the Frog mineral cartridge that contains Copper to also clean the water. The shock I use is a non-chlorine shock, commonly referred to as MPS (peroxymonosulfate). That is my oxidizer so I do not have to use Bromine or chlorine concentrate. One of the newest things to start happening in Hot tubs and pools are UV systems like what are used in hospitals. That are a bit pricey but in time will come down. They are installed in a pipe's line and as the water passes a high dose of UV light hits it directly and kills everything bad. Make sure you take the time to learn about the basic chemistry you need to use for whatever sanitizer system your using.1. I am having a serious problem with my cat urinating everywhere?The problem with your situation is this.. cats have SUPER smelling abilities and if there is a TINY trace of urine smell, they will keep peeing there, even when their urinary infection is gone.. SO the only option if your not getting rid of the cat is to invest in some expensive urine remover chemicals that are specifically for cat urine. Walmart sells this and its probably the cheapest you will find it, I like the brand "Out". SO you've got to start cleaning cleaning cleaning and if you really want to be sure, get a mini UV light (black light) and it will show you where the cat has peed so you can clean it up. Not to be vulgar but just in case you did not know, the UV lights show human bodily fluids like semen as well so if your looking on a bed and have a boyfriend it may not be pee. Again not trying to be vulgar, just informing you in case you did not know. SO if your keeping the cat, cleaning is your best option to be honest. ALSO I would not rush out to buy brand new replacement furniture but instead buy some from the thrift stores maybe until you get it figured out. EITHER way if you get a new bed, best investment ever- waterproof matress protectors! They make cheap plastic ones but the best are the cloth ones because they do not make you sweat and do not crinkle. But in a pinch you can get cheap plastic ones for like $3-5 at dollar general or walmart. Also they make couch covers. Cover your stuff up, it will make future clean up sooo much easier. Also rule of thumb is 2 litter boxes for first cat and one extra for every cat after. SO on one end of your building you need one and one on the other end. Hope i've helped.2. I have psoriasis and nothing seems to work. What can I do?Psoriasis requires general treatment, phototherapy, and drug therapy: General Treatment: Avoiding trigger factors Counseling and stress management Healthy diet Proper rest Regular use of skin moisturizers to prevent drying of your skin Take a daily multi-vitamin Vitamins E and C: talk to your doctor first Keep your skin clean Avoid skin injury and scratching Use a moisturizer to avoid skin dryness Expose yourself to sunlight: be sure to use sunscreen protection Consider moving to a warmer climate Aveeno oatmeal baths can to loosen scales Phototherapy Phototherapy exposes your skin to ultraviolet (UV) light. UV light is a normal part of sunlight that causes sunburn. Phototherapy is divided into two types: UVA and UVB light. Both forms of UV light help treat psoriasis. The treatments are usually combined with drug therapy (psoralen) to improve results. You may be exposed to sunlight for periods of time, or your doctor may expose you to special UV lights. Drug Therapy The type of drug therapy will depend on you and your condition. Not all people respond in the same way to the drugs used to treat psoriasis. Medications include: Anthralin (dithranol) Calcipotriene (Dovonex) and many others. have you seen a dermatologists?
Special UV Lights Could Kill Coronavirus on Surfaces
Researchers are developing ultraviolet LED lights that can decontaminate surfaces - and potentially air and water - that have come in contact with the SARS-CoV-2 virus.As COVID-19 continues to ravage global populations, the world is singularly focused on finding ways to battle the novel coronavirus."One major application is in medical situations - the disinfection of personal protective equipment, surfaces, floors, within the HVAC systems, etc.," says materials doctoral researcher Christian Zollner, a materials doctoral researcher at the University of California, Santa Barbara whose work centers on advancing deep ultraviolet light LED technology for sanitation and purification purposes. He adds that a small market already exists for UV-C disinfection products in medical contexts.As a technology, ultraviolet light disinfection has been around for a while. But now in light of the COVID-19 pandemic, attention has turned to the power of ultraviolet light to inactivate the coronavirus that causes the disease.While practical, large-scale efficacy against the spread of the SARS-CoV-2 virus has yet to be shown, UV light shows a lot of promise: Seoul Semiconductor in early April reported a "99.9% sterilization of coronavirus (COVID-19) in 30 seconds" with their UV LED products. Their technology currently is being adopted for automotive use, in UV LED lamps that sterilize the interior of unoccupied vehicles.It's worth noting that not all UV wavelengths are alike. UV-A and UV-B - the types we get a lot of here on Earth courtesy of the Sun - have important uses, but the rare UV-C is the ultraviolet light of choice for purifying air and water and for inactivating microbes. These can be generated only via man-made processes."UV-C light in the 260-285 nm range most relevant for current disinfection technologies is also harmful to human skin, so for now it is mostly used in applications where no one is present at the time of disinfection," Zollner says. In fact, the World Health Organization warns against using ultraviolet disinfection lamps to sanitize hands or other areas of the skin - even brief exposure to UV-C light can cause burns and eye damage.Before the COVID-19 pandemic gained global momentum, materials scientists at SSLEEC were already at work advancing UV-C LED technology. This area of the electromagnetic spectrum is a relatively new frontier for solid-state lighting; UV-C light is more commonly generated via mercury vapor lamps and, according to Zollner, "many technological advances are needed for the UV LED to reach its potential in terms of efficiency, cost, reliability, and lifetime."In a letter published in the journal ACS Photonics, the researchers report a more elegant method for fabricating high-quality deep-ultraviolet (UV-C) LEDs that involves depositing a film of the semiconductor alloy aluminum gallium nitride (AlGaN) on a substrate of silicon carbide (SiC) - a departure from the more widely used sapphire substrate.According to Zollner, using silicon carbide as a substrate allows for more efficient and cost-effective growth of high-quality UV-C semiconductor material than using sapphire. This, he explains, is due to how closely the materials' atomic structures match up."As a general rule of thumb, the more structurally similar (in terms of atomic crystal structure) the substrate and the film are to each other, the easier it is to achieve high material quality," he says. The better the quality, the better the LED's efficiency and performance.Sapphire is dissimilar structurally, and producing material without flaws and misalignments often requires complicated additional steps. Silicon carbide is not a perfect match, Zollner says, but it enables a high quality without the need for costly, additional methods.In addition, silicon carbide is far less expensive than the "ideal" aluminum nitride substrate, making it more mass production-friendly, according to Zollner.Portable, fast-acting water disinfection was among the primary applications the researchers had in mind as they were developing their UV-C LED technology; the diodes' durability, reliability, and small form factor would be a game changer in less developed areas of the world where clean water is not available.Related: Bleach not vinegar: How to clean to kill coronavirusThe emergence of the COVID-19 pandemic has added another dimension. As the world races to find vaccines, therapies, and cures for the disease, disinfection, decontamination, and isolation are the few weapons we have to defend ourselves, and the solutions will need to be deployed worldwide. In addition to UV-C for water sanitation purposes, UV-C light could be integrated into systems that turn on when no one is present, Zollner says."This would provide a low-cost, chemical-free, and convenient way to sanitize public, retail, personal, and medical spaces," he says.For the moment, however, it's a game of patience, as Zollner and colleagues wait out the pandemic. Research at UC Santa Barbara has slowed to a trickle to minimize person-to-person contact."Our next steps, once research activities resume at UCSB, is to continue our work on improving our AlGaN/SiC platform to hopefully produce the world's most efficient UV-C light emitters," he says.Source: Sonia Fernandez for UC Santa BarbaraOriginal Study DOI: 10.1021/acsphotonics.9b00600Find more research news at Futurity.org·RELATED QUESTIONWere can I get quality outdoor LED lighting for my landscape project?If short maintenance, eco friendly landscape lighting is a precedence for you, outdoor LED lighting is a ideal option for your landscape lighting design.

Some do not want to spend the money, others do not want the chemical taste that they can bring and some just do not like the idea of adding anything to their drinking water. For these folks there are options. Those options are: • Boiling water - This method has been used for thousands of years (10). Even before people understood what it was in the water that was sometimes making them sick they nonetheless realized that if they boiled water before drinking it that they would not get sick. Today, boiling water remains just as viable and effective a way of purifying water as it was during the days of ancient Egypt. If you arrive at your campsite to discover you forgot your water purification tablets you can just spark up the stove and boil your water before drinking it. It's also a pretty fast method of purifying water, since you only have to keep it boiling vigorously for a minute or two. The downside is that you have to wait for the water to cool down to drink it. And you will be burning up precious stove fuel. • Water filters - The typical water purification filter passes water through a cartridge that removes bacteria and other microbial life from the water. While today's commercially available water filters for camping and such are not able to remove some contaminants, they will often be sufficient to protect you from the major microbial players. Filters for home use are typically more involved and may use certain chemicals as well as UV light that kills off a wider array of nasty microbes (11). The downside of filters, especially for hiking and camping, is that they add weight to, and take up space in your pack.Biosynthesis of Flower-Shaped CuO Nanostructures and Their Photocatalytic and Antibacterial ActivitiesMethylene blue (MB, C H N SCl) dye degradation was carried using the as-prepared flower-shaped CuO-NSs. The setup and testing are provided in ESI. MB is a thiazine cationic dye which has an absorption peak at λ ≈ 663 nm (π π*) (Fig. 3a). Additionally, the absorption spectra of an MB solution photocatalyzed through H O (alone) and flower-shaped CuO (alone) are shown in Fig. S3. The H O was used to improve the degradation rate of the MB dye . The absorbance depends on the number of molecules reacted with it. The photocatalytic activity (absorption spectra) of the flower-shaped CuO peroxide (H O ) was observed when it is used as a photo-catalyzer of the methylene blue dye (MB) solution under UV light. It is seen from Fig. 3b that the intensity of absorption peak at λ decreases from 0.66 to 0.04 a.u. as reaction time increases from 0 min to 120 min and had no new absorption peak during the entire reaction process. This exhibits the comprehensive photodegradation of MB. Also, the histogram (Fig. 3c) shows that around 90% degradation was reached after 120 min of exposure of light which have a strong proof that the flower-shaped CuO effectively degraded the MB dye molecules. The graph of radiation time against ln(C /C) (Fig. 3d) shows kinetics ,65, of green synthesized flower-shaped CuO-NSs photocatalyst based on the model reaction. It follows pseudo-first-order kinetics. (A straight line in the slope is equal to the rate of degradation.) The rate constant of MB dye degradation by the photocatalyst flower-shaped CuO peroxide (H O ) is 0.05321 min−1. The possible proposed main reaction involved in photocatalytic degradation can be simply described as Eqs. 3-10:How do scientist produce genetic variations not found in natureSeveral different ways depending on the application.. .In genetic engineering such as with GM cotton, a gene from a soil bacterium that killed moths was inserted into cotton cells (gene was isolated, coated on a gold particle and shot into the cell). By doing it many times and screening the growths the plants where the gene successfully embedded in the Plant genome could be grown and bred from. In this case they have taken a gene from another species and placed it in a new species to infer a genetic advantage it did not previously posess.. .Another method, such as used in the controlled evolution of Green Flourescent Protein (an important protein for lab research that glows green when in presence of UV light; it was isolated from jellyfish and the gene expressed in bacteria.. It has also been used to map neuron growth and many other applications).. .As nature had evolved it it was only green. Researchers desired different colours so they copied the gene many times using Polymerase Chain Reaction (PCR). They let the copied DNA be degraded and broken up by special enzymes; they then added a different enzyme that reassembled the broken segments. These reassembled genes (with often very different sequences from the original due to degredation) were then placed into bacteria and expressed. By looking at the bacterial cultures with UV light they were able to select those beneficial mutations that had led to different colours of flourescence, grow them and isolate this evolved gene.. .Recently scientists have begun experimenting with simulating this kind of lab-based evolution on computers - research is still progressing.8 Best Air Purifiers with Washable Filters in 2021 - Reviews & RatingsThis futuristic-looking purifier stands at 26.1 inches tall.

This helps keep your skin soft, moisturized, and smooth. Bitter cold temperatures can affect the condition of your skin. Cold air, low humidity, and high winds outdoors strip your skin of much-needed moisture. Turning up the heat and taking hot showers indoors do the same. These harsh conditions cause your skin to lose its natural oils. This allows moisture to escape, leading to dry skin and potentially a winter rash. Other possible causes of a winter rash include: • sensitivity to antibacterial soaps, deodorizing soaps, detergents, or other chemicals • skin conditions, such as psoriasis or eczema Sunburns can also lead to a winter rash. The sun's ultraviolet (UV) rays can be potent, even in winter. In fact, according to The Skin Cancer Foundation, snow reflects up to 80 percent of UV light, which means can be hit by the same rays twice. UV rays are also more intense at higher altitudes. This is important to remember if you enjoy snowboarding, skiing, or other alpine sports.2012 Breakthrough AwardsWhat is it? An engineered metal mesh that is 100 times lighter than Styrofoam packing peanuts. It can be compressed by up to 50 per cent and bounce perfectly back into shape. The technology was developed by a team from Malibu-based HRL Laboratories, along with researchers from Caltech and the University of California, Irvine. How is it made? The basic structure is made when beams of UV light are shot into a light-sensitive liquid resin that hardens into a lattice structure. This is similar to the two-dimensional photolithographic process used to create microchips, but done in three dimensions. The resin lattice is then dipped into liquid metal, and, once the metal cools into a solid, the resin is dissolved away. What can it do? The resulting metal mesh is hollow and light, like bird bones, yet structurally robust. It can be used as a cushioning or insulating material in cars or aircraft, and it has potential applications in the medical field as a possible scaffold for new bone growth.The Magic MolekuleConsumers turned to Wirecutter with good reason: The purifier industry has been a swamp of misinformation and specious claims since long before there was a pandemic fortune to be made. There are now purifiers for your home, your office, and your car as well as ones you can carry like a clutch or wear as a necklace. Many manufacturers crow about their patented technologies, backed by studies of sometimes dubious quality. Beyond HEPA filters, which remain the industry standard, you can buy plasma generators, electrostatic precipitators, germicidal irradiators, needle-point bipolar ionizers, activated-carbon filters, dry-hydrogen-peroxide systems, ultraviolet lights, and a Kickstarter product made of "13 carefully selected plants known for their ability to purify the air" (never mind that experts estimate an 800-square-foot apartment would need more than a thousand plants to make any meaningful difference in air quality). Start a Google Alert for "air purifiers," and headlines like "Estonian Tech Firm Says Wearable Air Purifier Can Kill Virus With UV Light" will arrive in your in-box every day.Guidelines for Canadian Drinking Water Quality: Guideline Technical Document - Total Coliforms - Canada.caSimilar to ozone, UV light is highly effective at the point of treatment, but an additional disinfectant (usually chlorine or chloramine) needs to be added to supply a residual. When using UV light for the inactivation of E. coli (and other bacteria), the bacteria can undergo photo repair (i.e., photoreactivation) (Harris et al., 1987; Schoenen and Kolch, 1992; Zimmer and Slawson, 2002) and, to a lesser extent, dark repair. However, the amount of repair is not considered significant in drinking water treatment and distribution.
Does UV Light Kill Mold?
When you use UV light correctly, it will kill mold, mildew, and a range of additional pathogens. While this light can be placed anywhere in your home or facility, UV light is commonly used to kill mold within air conditioning units. While UV light is used by many industries for the purpose of killing mold, its primary application is microbial decontamination for air purification, water treatment, and medical purposes. When used at short wavelength frequencies, ultraviolet light is germicidal, which means that it can destroy and eliminate germs. The short wavelengths of UV light allow for mold to be destroyed as well.• You May Also Want to KnowCan a red uv light be on at night and not cause a stress on a snake?Snakes need a photo period light cycle;provide 8-12 hours of light daily;do not leave white light on at all times; to view snakes at night use a black or infrared light. If you use incandescent bulbs over a basking area to provide a heat gradient, you should use red incandescent bulbsWhere can I buy unfiltered uv light bulbs about 24" long?Do not know what you want it for.....but you can find UV lights that long from pond supply storesIs it okay to switch uvb and uv light?I would only use the heat lamp during the day until you can get a new lamp. They can go a week safely without UVB but they need heat to digest their food. Do not turn on the UVB at night as this will disrupt their day/night cycle which is more harmful than going without UVB for a day or two.So I just bought a uv light and found splatters of s 3 men all over my bedroom wall and sheets? How do I clean?In order to establish dominance, you must first urinate on the inseminated spots. After urination is complete, grab your nearest toothbrush and scream at the top of your lungs. This will frighten any timid sperm foolish enough to face you. Decimate the rest of them with your toothbrush of plaque-ridden doomWhy don’t commercial bread-baking plant use uv light & cold treatment to inhibit growth of bread mould?The bread is not in the plant for long enough to matter. It's almost immediately shipped out to retailers, where it sits on the shelf. That's where the mold starts growing, but no retailer is going to go to the expense of installing complicated controls like that. They rely instead on the bread being sold and eaten very quicklyPlease HELP! really easy..what does uv do to fabric???!!!!AND does uv light break up the molecular bonds?help!apparently it's not “really easy“!Does uv light for bearded dragon stay on at nightNo - it's not necessary at night. The UV light is simply replacing the natural UV radiation the lizard would get from basking in direct sunlight. We have to provide artificial UV sources, as UV light cannot pass through glass - which is why you cannot get sunburned indoors !PLEASE HELP ME can i use a fish tank light for my bearded dragon uv light source?If it is a fluorescent fixture you can use the fixture and just put a reptile rated UVB bulb into it. But if you are talking about just using a fish tank light as is, then, no, it will not be sufficient for use with a reptile.Can you put a bearded dragon in a different vivarium with just a uv light and basking light with no heatpadNo - you NEED to maintain the correct temperature range for the species ! The heat-pad provides general 'background' heat, while the basking light offers a localised 'hot-spot' and the UV light provides necessary ultra-violet spectrum.is it possible to make a home made uv light?sure - just get a “UV lamp“... this kind of thing is used to cure some kinds of glues...What property allows ozone to absorb uv lightThis is not some intrinsic property of ozone. In fact, any molecule would absorb a range of frequencies of photons. It just so happens that O3 covers the very range that is not covered by other components of our atmosphere, and thus saves us from the detrimental effects of UV rays of that range.What uv light should i buy for a russian tortoise?you will no longer even want thoes if he can get organic solar for approximately 4 to 6 hours an afternoon. my pink eared slider turtle lives exterior and he seems healthful with no longer something for warmth yet a water heater(confident he has a basking dock)does frosted glass block uv light?It depends on the plexiglass. Most will allow the UVA through, with the cutoff (blocking) happening in or beyond the UVB range. Some is made to cut off even UVA, so it depends on what kind of “Plexiglass“ you are using. Usually, the plexiglass that does filter most or all UV will be marked as that, because that is its selling point (if it does not say, it probably does not do it). Plexiglass is not “glass“ in the traditional sense. A different material. Regular glass will block much of the UV.uv light 253,4 nm safety?UV light has many of the properties of visible(red to blue to violet) light. It can be blocked by non-transparent objects, and can be reflected, and refracted. UV light can cause fluorescent materials to glow. If the fluorescent material is not glowing, there is no UV light. Compare fluorescent material glowing inside the lab, to not glowing in the dark hall way. UV light can go through solids like transparent glass, but not some kinds of transparent plastic like plexiglas plastic windows. Plastic Plexiglas just happens to absorb UV light, unlike transparent glass.uv light dc current [closed]You can take the circuit that powers a fluorescent lamp from DC (eg. a camping light) and replace the lamp with a germicidal one. The two types of lamps are electrically the same- the difference is that the one designed for visible light is coated with phosphor that emits white light and it has an envelope made of glass that tends to block UV-C 253. 7 nm light from the mercury discharge. UV-C LEDs are available now, but tend to be quite expensiveIf I bleach my facial hair won't it light up in black/uv light party for eg?Chemicals can enter the body through the skin. NEVER bleach facial hair.patches of skin glowing under uv light?You might have a common skin condition called : Tinea Versicolor. It is a superficial fungus infection, causing little to no symptoms. Primarily found on the trunk, it will glow under the Wood's lamp, or black light. That is one way to diagnose this condition. It can be self treated, if needed, with Selsun shampoo, or any other type of anti-fungal cream.I need help uv light I put my hand?Question for you: Did you pass the first grade? Your grammar could use some workdo you keep a snakes heating uv light on all day-night?Snakes do not require UV lighting, so if you mean their heat lamp, then no. They need to sleep. Think of lighting like the sun... on during the day, off at nightIf a substance absorbs infrared light does this mean it reflects uv light?A star does not reflect light, it emits light. Our eyes cannot see in the infrared but as the name suggests it is wavelengths beyond the red we can see. So if the star were emitting any visible light at all we would see it as a dull red.in regard to reptiles that require uvb light, would a HID HPS light hung4 ft. off floor provide uv light?The sodium HID's do not produce light in the correct spectral range for reptiles. Because they are sodium based they produce little UV.You need to use the mercury HID bulbs for the production of UVB . The ones marketed for reptiles are designed to emit the UV. The sodium bulb could still be used for general lighting in the enclosureWhat are examples of radiation and uv lightRadiation is a broad term since there are a lot of different types of "radiation." Example of Radiation include (but not limited to): Radiowaves, Microwaves, Infared, Visible light spectrum, Ultra Violet, X-Ray, Gammy Ray, and Cosmic Rays.. .Examples of UV light are UVA, UVB, and UVC. UVC does not penetrate the earth, but UVA and UVB do. UVA is responsible for sunburns and. skin cancer. after prolonged exposure, while UVB is tans for skin.. .A more popular UV example would be black lights.is there any other way than a uv light to make sure promise uv nail gel set?Well, if they are real UV gels, you need a UV lamp to cure them. However, it can be done without a UV lamp. This is NOT typically done and I would never do this with my clients but....UV gels cure by way of exposure to UV light, right? The sun is a great source of UV light. Soooo, the next time the sun is shining bright, try curing a very thin layer of UV gel by exposing it to the sunlight for a while - maybe like 10 minutes or so. I won't guarantee it, but it should work. Just sit at a picnic table or something comfy like that and hold out your hands so the sunlight falls directly on the gel. Give it a try! You might be surprised!can turtles get uv light through a window?yes they can get UV light through the glass!!Did UV light will help the electrolysis process?okay No UV light wouldn't increase the efficiency .. do make a better electrolysis cell you need a) a solution with ions when i did a project i used lemon juice its acidic and it worksb) i used the graffite which i.e is the lead inside a pencil i wrapped around 5 together to ensure a result .. c) you'll of course need crocodile clips to conduct electicity from and to the battrey ** you could choose the electrolyte of your choice =D experiment with different solutions like seawater which would release chlorine gas well hope that helped youWhat is the difference between spar urethane and spar varnish?Spar urethenes and spar varnish are different formulations. Urethene, naturally is a urethene based product, whereas varnish in the traditional formulas had linseed oil as well as various hardeners. On the old formulation the varnish never completely dried. This was so it would not dry hard and crack when exposed to great heat, UV light and salt water. (Try putting a hand on a wood rail or spar that has been exposed to several houirs of direct sun.) So it is a bit soft. If you use spar varnish on lawn furniture for instance, and sit on a sun warmed bench for a while, you will have to peel yourself off, and will see a print of the fabric pattern on the bench. I think the urethene product performe better in this last example, but it is also formulated to be very stretchy and flexible as well as resisting UV light which destroys most paint and varnish finishes. It sacrifices hardness in this same way as the spar varnish. Both types need to be sanded and re coated fairly often to retain their protective properties. Linseed oil (a component of spar varnish) turns dark in exposure to UV - which is why many antiques are much darker now than when they were first sold.Is UV light safe for household usage?You didn't say WHY you want to do this.......what are you trying to accomplish. UV damage takes time. Somebody can ripoff you home and not be affected by the light in such a short exposure. The level needed to damage someone would like ruin all the fabric in your home including the carpet. No, I think you need to come up with a different deterrent.What is the best treatment for psoriasis on the eyelidsI hear that natural olive oil and UV light can be very helpful for psoriasis and I do not think it will be to dangerous if a little get in the eyes.
