A Super-Efficient Light Bulb

[Science News]

Chroniton writes with news of a Silicon Valley company, Luxim, that has developed a tiny, full-spectrum light bulb, based on a plasma of argon gas, that gives off as much light as a streetlight while using less power. The Tic Tac-sized bulb operates at temperatures up to 6000K and produces 140 lumens/watt, almost ten times as efficient as standard incandescent lamps, and twice the efficiency of high-end LEDs. The new bulbs also have a lifetime of 20,000 hours. There's no mention of mercury or other heavy metals, which pose a problem for compact fluorescents.Read more of this story (http://hardware.slashdot.org/article.pl?sid=08/03/22/2049257&from=rss) at Slashdot.

Woo... very neat. All of the bulbs in my house are either CFL or LED. The LEDs are great for the kids night-lights - they're not too bright, don't get hot, and virtually cannot be broken (if my kids can't break them - I challenge anyone to try).
