Submission + - The Lightbulb of the Future (zdnet.com) 2

Chroniton writes: Using a tiny amount of argon gas plasma, a silicon valley company has developed a lightbulb the size of a Tic Tac that gives off as much light as a streetlight, but at full spectrum (CRI=91) and using less power. This new type of light burns at 6000K and gives off 140 lumens/watt, ten times as efficient as standard incandescent lamps, and twice the efficiency of LEDs. The new bulbs also have a 20,000 hour lifetime.

The Lightbulb of the Future

  • The company seems to be looking toward future long life projector bulbs. They need to step this up to 6500K for standard white temps. http://en.wikipedia.org/wiki/Color_temperature [wikipedia.org] Projector bulbs that last 10 times the current life are very interesting.

      I believe when the other poster referenced 6000K, he/she wasn't referring to a color temp, but the hot spot at the center of the plasma (i.e. the same temp as the sun's surface). Their CRI = 91.
