CFLs vs LEDs
http://money.cnn.com/2007/02/13/magazines/fortune/gunther_pluggedin_lightbulb.fortune/index.htm
CFLs, as they're known, cost more than old-style incandescent bulbs, but they last longer, use far less electricity, save consumers' money in the long run and reduce greenhouse gases.
All of which is well and good. But the next, next big thing in lighting could turn out to be the technology known as LEDs, or light emitting diodes, which are a whole lot "greener" than CFLs. The newest LEDs use even less energy than CFLs. They last for as long as a decade. And, unlike CFLs, they are mercury-free.
LEDs are being rolled out as the technology has improved and costs have dropped. LEDs have a lifespan of up to 10,000 hours, or 11 years. That's why they are now in more than half the traffic lights in the U.S.
California says discarded CFL bulbs must be treated as toxic waste because they contain mercury; this year, believe it or not, state legislators have introduced bills that would eventually ban incandescent light bulbs.
