Seoul semiconductor has created a light emitting diode that emits roughly 240 lumens and claims the highest efficiency (amount of electricity to amount of light) of any light source. Fluorescents hit 70 lumens per watt, incandescents max out at 15, but this new LED emits roughly 100 lumens per watt. The results, if and when this technology gets cheap enough for the mass market, will be smaller, more efficient light sources, and lights that can exist in far different form factors than the current bulb or tube shapes. The devices also have applications in consumer electronics, specifically LCD back lights and projectors.LEDs with similar efficiencies have been produced at universities, but this is the first time a corporation has begun creating these superefficient LEDs. Seoul Semiconductor says that, while this advancement is significant, they're moving forward with even more efficient LEDs. They expect, for example, a 145 lumen per watt LED by 2008, which would double the efficiency of standard compact fluorescents. We just have to wait and see how expensive they are.
