The enthusiasm over LEDs is misguided. Nobody's demonstrated an LED lamp for general lighting that outperforms a CFL. Some get close, but close is still inferior. The efficiency and price have to improve a great deal before LEDs make an impact on the amount of energy we use for lighting.

Meanwhile, fluorescent isn't sitting still. The 28W GE WattMiser T5 lamp is available with up to 108lm/W - 70% more efficient than my CFLs. If they scale that technology down for a residential application without losing too much efficiency, that will set the bar even higher for LED lighting.

I'm not convinced LED is the wave of the future, in terms of efficiency.
