RE: Lighting the world with LEDs
This is an exciting development. I presume this new light source also produces less residual heat. I that correct?
I've converted nearly all of our incandescent and compact florescent bulbs to LED bulbs and have been very pleased with the light they emit. The initial cost per bulb is high, but the operating costs are much lower. Unfortunately, the local power company, PSE, is still pushing compact florescents, despite the fact they contain mercury, so there has been no program of replacement in the Seattle area. It is strictly voluntary.
