One THOUUUUSAND lumens, baby.]]>Sep 21st 2007 12:20PMhttp://www.engadget.com/2007/09/21/seoul-semiconductors-420-lumen-led-puts-the-sun-to-shame/http://www.engadget.com/2007/09/21/seoul-semiconductors-420-lumen-led-puts-the-sun-to-shame/
That's not truly an amazing feat anyways. I could hook up 1000 standard 100 lumen LEDs and have a theoretical output of 100,000 lumens. That's why this LED is amazing, it is so powerful in a single package.]]>Sep 21st 2007 12:34PMhttp://www.engadget.com/2007/09/21/seoul-semiconductors-420-lumen-led-puts-the-sun-to-shame/http://www.engadget.com/2007/09/21/seoul-semiconductors-420-lumen-led-puts-the-sun-to-shame/
And that article is relatively old about the 1000lm LED, so I would say Seoul is a little behind.

Read the link. You can't see the six individual LEDs because of the "light" being emitted from them in the picture, but according to the article, there are six.]]>Sep 21st 2007 1:48PMhttp://www.engadget.com/2007/09/21/seoul-semiconductors-420-lumen-led-puts-the-sun-to-shame/http://www.engadget.com/2007/09/21/seoul-semiconductors-420-lumen-led-puts-the-sun-to-shame/
But it's all about lumens per watt for general purpose and residential lighting, so while the output is remarkable for a small package, the energy consumption is still relatively high compared to many other technologies, including fluorescent.

Earlier this year some were celebrating the supposed rush of LEDs in the consumer space for general lighting. Sorry, not going to happen for quite a few years. Efficiency is not there and production costs are certainly not there yet. I still predict at least 5-10 years until LEDs make for a viable residential lighting solution.

1) smaller. Lights that have to fit into small spaces without creating huge amounts of heat.

2) dimmable. You can dim an array of LEDs but cannot dim a CFL. (although some CFLs have a 3-stage light ability.)

3) lifespan. These little buggers can be turned on and left on for a decade. If you have can lights in a vaulted ceiling, you may never have to change the light as long as you live in the house (assuming average homeownership, blah blah blah.)

CFLs cannot fill all the niches incandescent lights do, but LEDs and CFLs together get darned close.
