I’ve never really been a fan of compact fluorescent bulbs because of the mercury, though I certainly love to save energy. Now there’s a new concern: harmful ultraviolet radiation. What?

A Stony Brook University study says that the University “has proven that CFLs do emit ultraviolet (UV) light rays that can harm human skin cells.” Oh my. The issue seems to be in the milky white phosphor coating inside the glass. If it’s cracked, it releases harmful radiation from prolonged exposure at short ranges.

And, the news gets worse.  All of the CFL light bulbs that Stony Brook University studied had cracks in the phosphor coating.

I think that LED lights are preferred, until further notice.
