World Record Brightest LED

today Osram (yes, the lightbulb people) has news that they've pushed white LEDs to world-record brightness. By optimizing the diode, light converter and the package, their lab test squeezed 500 lumens out of a single LED at 1.4A. That's bright enough for projector tech, and certainly makes the single unit good for car lighting and even interior lights. At a lower, more optimal, current the 1mm-square white LED had an efficiency of 136 lumens/W which makes it about twice as efficient as standard fluorescent lamps and 10 times a normal bulb.

Hmm wonders how much the bulb or an array will cost?
