The curlicue compact fluorescent lamps (CFLs) oft touted as an Earth-friendly alternative to standard incandescent bulbs may cause skin damage, according to a new study by researchers at Stony Brook University.
The bulbs are already known to pose hazards from using mercury, a toxic element, though in very small quantities, as lighting manufacturers are quick to point out. Regulations in parts of the United States and in the European Union limit mercury to 3.5 milligrams per bulb, with the limit dropping to 2.5 mg next year.
Now researchers have found that ultraviolet radiation seeping through CFLs may damage skin cells. Miriam Rafailovich, a professor of materials science and engineering at Stony Brook, led the research after reading an article in an Israeli newspaper that reported a spike in skin cancer on a communal farm when residents switched to fluorescent bulbs.
“In the past two years some disturbing reports have surfaced mostly in the European Union literature, which indicate that exposure to CFL bulbs might be responsible for exacerbating certain skin conditions, such as photodermatoses and skin cancer in humans,” says the paper, published last month in the journal Photochemistry and Photobiology.

Hmm. Which type of UV? UVB is what your skin uses to produce vitamin d that your body converts to powerful cancer fighting hormone Calcitriol. UVA is much stronger, capable of penetrating deeper except for sunblock lotion. I’ve read that too much UVA exposure can breack down vitamin d in the body. I haven’t really looked into it though.
Low ballast bulbs emit UVB and that’s what doctors sometime recommend to treat skin disorders. Of course, most dermatologists are against that. They are just as bad as hansen, etc when it comes to actual science behind sun and it’s effect on health. Oh well.
My hired hand used a cfl in a light holder when painting a room. He actually got a “sun burn”
Brilliant title. Says it all in a nutshell.
