Super-Efficient, Cheap LED Lightbulb Tech Near Production

Fuggeddabout the hazardous, if politically correct, compact fluorescent lightbulbs already. They'll soon be replaced.

Story here.

Now a team at Cambridge University may be close to having a winning design on their hands, perhaps for the L Prize, if they're eligible, and for the consumer market. The university has produced a new design which costs a mere $2.85 USD and despite being the size of a penny, produces similar light to a fluorescent bulb while lasting over four times as long with a lifetime of 60 years.

The new design triples fluorescent bulb efficiency and is 12 times more efficient than incandescent designs. Also, it’s capable of instantaneous illumination, so the light lag associated with fluorescent bulbs may soon be a thing of the past.

If installed across all of Britain, the researchers estimate that it could cut the country's lighting portion of the energy budget from 20 percent to 5 percent a year. The U.S. could muster a similar 10 percent drop with the design, according to recent DOE estimates. The new bulbs last 100,000 hours and unlike other "eco" bulbs, they contain no mercury, a substance that can cause brain damage in humans. They also don't flicker, while other green designs do, something that's been blamed for triggering epileptic fits.

Cool way to shave a few bucks off your electricity bill. And avoid the risk of toxic mercury contamination from broken fluorescent bulbs and so on...

I look forward to purchasing such new LED bulbs in the future when they're available.
