Does the light give off dangerous UV rays?

No. This light projects light at Light Spectrum: 460nm, 610nm, 630nm, 730nm;(according to the manufacturer), which is ideal for plant growth. Ultra violet light is lower on the spectrum, 10-400nm (according to wikipedia).

Yes I can see the UV light . My room is 13' x 15'. I turn the UV light off at night

HI There....I believe no UV rays are emitted. RV I am not sure about. I would call Phillips lighting 1-800-555-0050 to see if they can answer your questions. I hope that helps.

Yes, it is my understanding that it has everything to do withe the intensity of the light. It is not providing any UVA or UVB rays which might be filtered out by glasses. I wear my glasses while I sit next to my Happy Light and read or work on my computer. So does my mother.

Yes, but you have to cover everything with a towel to block the UV light inside.

No UV light is emitted from the RedMD. We include goggles which must be used with each treatment.

it is possible... problem is accessibility to surface that needs to be exposed to this light. UV light acts on the surface... mold and mildew are often below the surface as well as on top and in crevices. this light is not designed for continuous exposure to a surface, which is what mold and mildew control would require.

Perfectly safe. The amount of UVA/UVB is vanishingly small more than 2 feet away from the bulb, and even at very close range is much less than from the afternoon sun. I think getting a slight burn from touching it after it has been on for a while is a more serious hazard, though its heat output is only in the 40W incandescent range. One should remember, though, that these are flourescent bulbs, and all the warnings about breaking this kind of bulb apply.

Yes, all UV-C products produce dangerous amounts of ozone! See: http://www.newton.dep.anl.gov/askasci/chem03/chem03323.htm

Yes. There is a button on the top surface labeled UV. That button contols the uv light being on/off.

Black light, also referred to as a UV-A light, Wood's light, or simply ultraviolet light, has been linked to the development of skin cancer in humans.It does have the potential to accelerate skin aging and cause wrinkles. Although with the relatively low power of bug zappers, the risk is fairly low, it is still advisable to place it as far from humans as practical, and use the lowest power that will do the job.

There is a little door on the side of the unit that opens up. You will see the light from the UV bulb shining through if it is on. (Read your manual!)

Yes these LED lights will produce UV Light. That is how it works. You need the UV to dry the nails.

The effective range of this style of UV-C lamp is quite small and the bulb can cause eye irritation. This is why the lamps all have fans to intake air then irradiates bacteria within the sealed chamber.

Hello. The UV Light is what creates the reaction with the Titanium Dioxode that gives off the CO2, so you can't have one without the other. Thank you

I believe the answer is "yes" due the wavelength of the UV light (it doesn't matter what you're looking at - it's the light that's harmful). The glasses are cheap protection for your eyes.

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.
