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!
Of course, the Republicans in congress will be attacking this light bulb in a future congressional session. This light sounds too good to let it live.
