There is a push today to phase out incandescent light bulbs in favor of Compact Fluorescent Lamps (CFLs). Supposedly, incandescents convert most of their electricity to heat, don't last long, and cost a lot to operate. CFLs, on the other hand, operate on less power and lasted forever. Sure, they couldn't be operated on dimmers, for the most part, and they contained mercury, but those were reasonable trade-offs.
If your experience has been like mine, you've seen that CFLs generally don't last as long as promised, unless they're in special locations where they are left on for extended periods, and they remain expensive and provide generally inconsistent light. Incandescents seem to be a better buy in many situations, even if they gulp more power. I thought maybe I was doing something wrong until I read this article from a former Bell Labs engineer about some of the problems with CFLs. There are more problems than I was aware of. Looks like we better just wait until we can buy LEDs.
