Philips won the 60W A19 L-Prize, with a 9.7W bulb that puts out 940 lumens. They’re available commercially now, and someone’s posted a great technical teardown of it, including its emissions spectra.
Philips has won the DOE’s L-Prize
The US DoE set up the L-Prize, modeled after the X-Prize, for durable, high quality, low power lighting. Philips just won it, with a remote-phosphor LED bulb. Warm white light, 900 lumens bright, for less than 10 Watts. Now if only they can get someone other than Home Despot to carry them!
