When these get cheaper...

LED Lights vs Incandescent - CFL vs LED Lights - Popular Mechanics: "Solid-state lighting has long been touted as the next generation of efficient bulbs, but technical challenges have so far limited product offerings to 40-watt equivalents—and consumers haven't exactly rushed shelves to purchase bulbs to read by. Developing light-emitting diodes (LEDs) that generate full-spectrum color—white light—is particularly difficult. Another hurdle has been finding a way to efficiently manage LED temperature: If the bulb gets too hot, it fails. Now, the first LED bulbs to rival the 60-watt, screw-in incandescent are finally poised to hit the market."
