Better, cheaper LED's

Too bad Dalton. The days of the mercury-laden compact flourescent light (CFL) may be numbered...

The incandescent lightbulb that wastes 90% of the electricity as heat is dying, we all know that. But a new breakthrough in solid state lighting might also kill compact fluorescent lightbulbs (CFLs) faster than some expected. Scientists at Purdue University have figured out how to manufacture LED solid-state lights on regular metal-coated silicon wafers (more details below). What this means is: much lower costs.

I live in an old farmhouse in Nebraska. In the wintertime I use incandescent bulbs for both light and warmth.

Wow, a ten percent reduction over the old incandescent bulb. I would have thought it would be higher. But the LED lights should last infinitely longer. As an alternative to those damned CFL thingies, I'd use them in a heartbeat.
