The DOE also set up an L Prize contest, a competition to make a 60-watt-equivalent light bulb that uses only 10 watts. Philips was the first to submit an entry, pictured here. The company said it plans to bring a 60-watt-equivalent LED, which is set to go on sale by the end of this year. Dispersing light evenly from an LED can be done in different ways, including optics inside the bulb. Philips will have a phosphor coating on the bulb itself.
