You would be right on there.



Potential fire danger too:

Did I mention these Turdcoil bulbs leak out UV radiation !

CFLs actually leak out fairly high levels of UV radiation. It has to do with how they work. The inside of the tube contains mercury vapor. When an electric discharge is passed through, it causes the mercury to give off UV radiation. This radiation hits the phosphor coating on the inside of the tube, causing it to glow. However, some of the UV radiation leaks out. Spiral CFL tubes emit several times more UV than regular fluorescent tubes because during the manufacturing process, when the tube is twisted into a spiral shape, small cracks are formed in the phosphor coating inside, allowing more UV to get through. Because of this, CFL bulbs are NOT an option for me, since I am one of the small number of individuals very sensitive to this. The radiation emitted from CFLs makes my skin feel sore after about 15-20 minutes, and they also strain my eyes. It feels like "snow blindness", and my eyes continue to ache for many hours afterwards.

Although I am more sensitive than most, I cannot imagine all this extra UV exposure is good for everyone else either.
