UV-C: Aren't UV-C rays, the skin cancer-producing rays?

you aren't being exposed to the light in these units, only the germs in the air that passes inside it are, and you are thinking of UVA and UVB rays

My thought was yes. UVC is a short wavelength and that is why it is blocked by our atmosphere. So it is easily blocked by glasses and probably plastic as well, especially plastic that we know blocks UVA and UVB rays. Here something from Wikipedia: Ordinary glass is partially transparent to UVA but is opaque to shorter wavelengths, whereas silica or quartz glass, depending on quality, can be transparent even to vacuum UV wavelengths. Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm. So with resonable confidence yes they block UVC, which is what germicidal lamps put out. Watch out for your exposed skin though.

If you are worried about this sort of thing, you had better stop using your microwave, unplug your wifi router (oh yeah, and all of your neighbors' wifi routers, too), stop using your cell phone, and don't ever expose yourself to sunlight! Seriously, though this article that you cite (and yet don't link to it) is probably in a popular magazine and has not been peer-reviewed by members of the scientific community. Don't believe everything that you read!

I know what UV sun rays are but I have no idea what RV rays are. I thought an RV was some kind of a vehicle. I haven't got a tan from the bulb or burn so I would say no, however I've only had it a short time. There might be better sources than other customers though. Sorry. trin.

That is just a sunblock. The title is wrong, it's not a moisturizer and sun screen. It's just sunscreen. See the actual product packaging. That one is also thicker in consistency if I remember correctly.

The manufacturer doesn't have a bulb replacement and that is one reason why its a UVA and not UVC bulb. The latter needs to be changed every 6 months or so as indicated by their other products and is also more effective against germs.

Regarding the "ozone" concern.....the company states the following:"No ozoneA specially designed UV-C light bulb is used so no ozone is produced. The UV-C light bulb (model LB1000) needs to be replaced every six to eight months depending on use."I personally had one and loved it. Ran smoothly!

No or very little. UV rays are what make you tan, tanning in itself is a bad idea (even though I do it lol) that's why you hear about people developing sun damage or skin cancer.

yes,that might happen. Especially if when you go outside,you don't protect your skin and wear sunscreen.

I'm not a molecular scientist but i do believe the exposure to the uv light is extremely minimal.Need notworry about sunburn.

No it isnt. If you want vitamin c for its skin brightening properties then this isn't for you ( per say ) This is for moisture only. I hope this helps.

This one specifically doesn't, but in it's label says: "for daytime sun exposure, use Avalon Organics Vitamin C Renewal Moisture Plus SPF 15"... maybe Amazon sells that one too :)

Hi....I don't see it listed. The main ingredient is pure vitamin C. I know it worked for me. It's not an over night cure. Must have patience.

No, 99.3% of the UV produced by the bulbs is blocked for safety. Vitamin D from Sun exposure is due to the UV and bright light therapy is believed to work through the bright light hitting the retina and causing changes in the actions of the pineal gland. Please make sure to check legitimate medical sources for more detail and authorative information.

I am not totally sure of that answer, I just figured it was like clothes, if its covering up you aren't getting the full impact of the UV light, just like when you are out in the sun, your clothes protect your body. I think its better than not using them at all.

You can see a slight glow from the back of the unit. I use it in my bedroom at night, and it's not bright enough to keep me awake. I certainly wouldn't worry about the UV radiation.
