BoingX2 - LED's Throwing Some Light on the Hype
 An LED light that can replace the incandescent bulbs and/or CFLs you have  lighting up your home right now. To do it right, you don't just need a single  LED that works, you need an array of them...and you need them to produce enough  light, and the right color of light, reliably enough that people can buy an LED  bulb and know what they're getting into.That ain't easy. But it is  getting easier.

There Are Good LED Lights Out There; But You Probably Can't Afford  Them
See, the LED industry is kind of in this awkward teenage phase  right now... There's a lot of misrepresentation and a lot of flat-out lies, and  just because a box says something that doesn't mean you can believe it (more so  than boxes of other things). In fact, up until last year, there weren't really  any useful standards to compare LED lights. Anybody could make any claim  they wanted to and even the professionals had nothing to judge it by. That's  changing, but for now, assume you're dealing with the early 20th-century patent  medicine industry. 
Again, yes, there are good products and there are honest companies. But finding them takes a LOT of research.
The DOE is trying to fix that,  though. One way they're fighting back is with CALiPER,  basically a secret-shopper program with a lab experiment twist. Researchers from  the Pacific Northwest National Laboratory (and other labs) purchase LED bulbs  and fixtures anonymously (often via third-parties) and run them through an  extensive testing process to see whether they live up to the claims on the box.  The majority still don't, though it's getting better. More than 175 products  have been tested since 2006.
