Are my eyes deceiving me? I bought some Reveal CFLs from Target yesterday, and I think I actually like the light they produce more than light produced by the Reveal incandescent bulbs.

Are you not supposed to use a CFL in a ceiling fan fixture unless it says you can on the package?

Daylight CFL's have been available for as long as CFL's have been available.
These are nothing special or nothing new, AFAIK.
I've experimented with daylight CFL's. The Reveals produce light that feels warmer and a lot less sterile.
Lumens is for brightness Color Temperature is the quality of the light. Most fluorescent bulbs run toward the green/blue end of the scale while the so called "warm white" shifts it toward the red end.

The eye is most sensitive in the yellow area of the spectrum, so the warmer phosphors also appear brighter for the same actual lumens. They claim that CFLs only degrade (lumens) about 20-30% over their lifetime (about one f-stop) which is barely noticeable. Most CFL ratings are initial lumens.
I like halogen bulbs for some applications and there are technologies in development to bring efficiency to near CFL levels.

I'm not so sure about these GE Reveal CFLs anymore. The past two days I had a persistent headache. I reverted back to incandescent bulbs, and now I feel better. Of course, correlation doesn't imply causation, but I think I'm giving up on CFLs.
I prefer the light from CFLs over incads. It's a brighter whiter light I find, illumunates the room with better quality. I installed some in my basement, thinking of putting more.
Actually, I believe the eye is most sensitive to the color green.
