The reason that there aren't white LED lamps is the same reason that
there aren't battery-electric airplanes. Right now, for "white"
light, fluorescent lamps are just about the most efficient thing
around. To make money, LEDs have to beat fluorescents and they aren't
quite there yet - but probably will get there within the next few years.

Matt,

Actually, that's not quite true. LEDs have just hit efficiencies of
90 lumens per watt, which is comparable to compact fluorescent. The
biggest barrier to LED light bulbs right now is cost, but that should
also change soon.
