In a few years, LEDs will be ready for general purpose lighting.
THAT’s what I’m waiting for. LEDs. Those are the true lighting revolution.
“But you are starting to see LED lights more and more.”
OMG an LED contains gallium and arsenic and lanthanum! Run! < /s
LED's make an excellent light source. You see them now in many car brake lights and flashlights. I've read notebook computers as well as LCD TV's will be switching from fluorescent backlights to LED's. LED's seem to have all the advantages of low energy consumption, long life, and no heat production. The only downside is cost, but that will come down as usage ramps up.
