Compact, fluorescent, dangerous

Just minutes apart come two tweets about compact fluorescent lightbulbs. First this from Revkin:

Edward Hammer, inventor of helical CFL bulb, has died, age 80.

And then this from Ken Green.

Besides being expensive, undimmable, slow-to-brighten, giving off ugly light, and containing mercury, compact fluorescent bulbs apparently give off UV radiation that will damage your skin.

One assumes the close proximity of the tweets is coincidence.
