"CFL's are fluorescent. Some people get headaches from the light, or they see the 60 cycle flicker and can't read by them, or they hate the color of the light, or they hear a faint buzz."

When I worked in Power Plants in the Control Room this was a problem for some of the operators. We used to disable or shade some of the lights. I was never sure if the glare off the gages and instruments caused it or the frequency of the lights. I've been reading for hours using one of the energy saver bulbs and it hasn't bothered me. Just the normal eye tireness I've been getting the last few years.
