LED’s Good Housekeeping Seal, by Eric A. Taub, in the New York Times’ “Bits” technology blog –

“Some LED products are only delivering 30 percent of the illumination that they claim,” said James Brodrick, the Department of Energy’s solid state lighting head.

To stem the disaster of a potential consumer backlash against a
technology that, done right, could have major positive environmental
impacts, the D.O.E. is bringing LED lighting products into its Energy
Star program.

Those products that get Energy Star certification
will have to perform according to a set of Energy Department
guidelines, as to the amount of light they produce and their effective
life.

A handful (but just a handful) of products have received the Energy
Star imprimatur. But Mr. Brodrick thinks he’ll have up to 300 LED
certified products by the end of the year.
