LEDs Find Their Way Home

A study published yesterday by Osram, a German Lighting company, proves once and for all that LED bulbs and lamps require less energy to manufacture than incandescent bulbs. And the differences don't stop there: While incandescent bulbs last 1000-2000 hours, LEDs have a lifespan of 25,000 hours, and can reduce energy bills by as much as 80 percent.

So why doesn't everyone own an LED lamp?
