Light-emitting diodes, or LEDs, are the most efficient and environmentally friendly light bulbs on the market. But they come at a higher up-front price than other bulbs, especially the ones with warmer and more appealing hues. Researchers at the University of Washington have created a material they say would make LED bulbs cheaper and greener to manufacture, driving down the price. Their silicon-based nanoparticles soften the blue light emitted by LEDs, creating white light that more closely resembles sunlight. The company, LumiSands, started as a graduate student pr...

LEDs are extremely efficient, and when it comes to single colors such as red or green commonly used in traffic lights or toys, they can’t be beat. But those aren’t the colors we want to light up our homes and offices. Our eyes prefer the warm, white light produced by the sun, and when it’s not available, we’ll take the similar glow produced by CFLs and incandescent bulbs. Soon, however, those traditional options won’t be available, and good riddance. They suck up way more energy than should be necessary to light a room. Scientists have been worki...
