I have no idea, I put them in a line of lights on my ceiling. They are not as bright as the ones I took out and I don't think they are hot.

I was thinking the same thing. I am thinking about buying a reptile light they make uvb

From tech support at Hydrofarm: Thank you for your inquiry. The bulbs emit an extremely small amount of UV. I suggest getting bulbs specifically for UV light. Feel free to reply with any further questions.

Hi! My own experience: bought the duck 2 days ago. I have a screen-enclosed pool like you do. Exposed the animal 5-6 hours in full light/sun exposure yesterday. The LED light turned on at dusk, as expected. Very nice. Am ordering a second unit today! I really don't see why the screen would prevent the sun to activate the solar cells, it does not prevent my wife to get a beautiful suntan... Nothing to do with the screen, provided you have direct sunlight. Unless you have big trees or some other reason preventing the sun to go through. Enjoy it, or return it to Amazon, if you're not happy! Hi! My own experience: bought the duck 2 days ago. I have a screen-enclosed pool like you do.

Uvb 5.0 is what I used for my turtles, the 10.0 may burn their eyes. Remember this only provides daylight, its not hot. You need an extra source of heat so they bask in the sun. Also new uvb lights give off a higher intensity in the beginning, so I suggest keeping it at a further distance for the first two weeks of use.

Theoretically a little over 3. I have not seen over2.2 usually just under2. 2.2 was ideal sun exposure and cleaned panel.

UV-B is the UV you need to worry about, but it's in the 280nm - 315nm range. UV-A is essentially what's known as blacklight, in the 315nm - 400nm range. Starting at 400nm, we get violet, of the visible and non-ultra kind. So this 395nm light is at the safe end of blacklight. No need to worry. It's OK for lighting up phosphorescent material, but not even close to the kind of UV you get at the tanning salon.

My turtles died after 3 months due to MBD (lack of UVB exposure for calcium uptake) even though the product claims UVA, UVB & heat are present in this 1 bulb. For UVB source for your pet, please provide a second dedicated lamp for UVB and/or take pet outside regularly to bask under the sun. Also, some have referenced that UVB bulbs should be replaced every 6 months. So if you buy this product just use as heat & UVA source, but please get a 2nd lamp for UVB source (do this for your pet's health).

It doesn't say anything about UV on the package. The graph shows little output below 400nm, <5% daylight. It's equivalent to a 10w fluorescent and a 50w incandescent.

This flashlight puts out near UVA light, at about 400 nm. Humans can see down to 385 nm. Bright Sunlight has more radiation at this wavelength than this flashlight so our eyes get exposed to this level of near UV light for hours at a time if you don't wear sunglasses. UVA is hardly filtered by the ozone layer so almost all UVA reaches us and this flashlight produces light at the very edge of UVA and visible light.People fear UV but it is the deep UV that harms you. Turn the light on and put it on your arm. Do you get sunburn that is caused by UV? No way. Put your arm under a DEEP UV light and it will cause redness. Just use a regular pair of sunglasses if you want but it is unnecessary. This flashlight puts out near UVA light, at about 400 nm. Humans can see down to 385 nm.

I have a timer on my tank so the sterilizer cuts off when the hood light goes out after 10 hours each day. My bulb lasted a year. Home Depot sells replacement uv bulbs for about 10 dollars.

Yes it has UV protection! It blocks out more sun than it looks like it would! I absolutely love this cover!! Don't know the weight but it's not really heavy! We covered our percula with it! Love it!

This pdf seems to answer your question. Seems like the lamp uses a halogen lamp? http://www.public.health.wa.gov.au/cproot/1391/2/Ultraviolet_Radiation_from_Quartz_Halogen_Light_Sources.pdf

I have two Sunsun filters. In order to see any color (and it is very faint blue) you must get your eye directly over the top of the small lens. Don't stare for long. UV can cause eye damage. The fact that you see any light tells you that the bulb is lit. Don't run it continuously. Only when you seem to have a clarity problem. Otherwise, you are wasting the life of the bulb. Also, do not turn on the light when you are cycling the tank. It will kill the nitrifying bacteria in the water column. This permits it to be seeded on various surfaces in your tank including your filter media, gravel, rocks, etc. I have two Sunsun filters.

Yes, there is one switch for the heat and one for the UV light. You can turn off the UV at night with its switch and keep the heat on. That is what I do and my beardie loves it. Just as a side note, my beardie loves it:)

The one I bought was not UV, although Tetra does have the ability to use one with it. I'm not really an authority, but if you are interested, you can go to their website to see the different models and what they include.

I believe you meant a 55 gallons barrel, anyway it would work. Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses ultraviolet (UV) light at sufficiently short wavelength to kill microorganisms. It is used in a variety of applications, such as food, air, and water purification. UVGI utilises short-wavelength ultraviolet radiation (UV-C) that is harmful to microorganisms. It is effective in destroying the nucleic acids in these organisms so that their DNA is disrupted by the UV radiation, leaving them unable to perform vital cellular functions.
