Just received this from a family member and wondered if anyone has looked into it? http://www.globaltv.com/globaltv/globalshows/16x9/video.html?maven_playerId=16x9extralargeplayer&maven_referralPlayl
Well, I'm not going to watch a video, but here's a link to the FDA's page of information on CFLs: http://www.fda.gov/CDRH/radhealth/products/cfl.html " Do CFLs emit UV? All fluorescent lamps emit som
Some more than others. I use them around the house and can't say that I have noticed any difference. "A slip of the foot you may soon recover, but a slip of the tongue you may never get over." Ben Fr
All fuoroescents generate UV; CFLs are no exception. The UV hitting the inside coating of the glass causes it to glow (fluoresce) with visible light; and that's how they generate light. The glass hop
The claim of the researchers is 10x+ the UV radiation of a typical incandescent. I had trouble with the audio so could not make out a lot of the details. -- Thanks! & 73, doc, KD4E FS/Swap/Wanted: ht
I was hoping for someone more qualified than me to evaluate the efficacy of the competing claims. -- Thanks! & 73, doc, KD4E FS/Swap/Wanted: http://kd4e.com/swapn.html Free OS : http://www.PuppyLinux
At the heart of all fluorescent bulbs (tubular, miniature, or CFL) is a low pressure mercury discharge. When excited, a mercury discharge will emit copious amounts of UV energy at 254 nanometers (nm
Sure, I buy that. There's basically a vanishingly small amount of UV radiation in the thermal light distribution coming off an incandescent. Check out the Wikipedia graph of thermal emission spectra:
Jeff, W3KI, shared some interesting perspective. Others have noted that we often may have a CFL in much closer proximity than a common florescent tube - so even if the CFL UV level is similar the con
If it's 10 the average incandescent it'd take some very sensitive equipment to even know it's there. IOW, just scare tactics. Even the big tubes close up give off very little. I have 22 8' tubes in m
That wouldn't surprise me. Incandescents emit light by way of what physicists call "blackbody radiation," which everything in the universe emits, proportional to its temperature above absolute zero.
