LED lights are very cool. They efficiently emit bright light, for a long time, and stay cool to the touch. But why stop at nifty head lamps and Christmas tree strings? Dutch carpet manufacturer Desso is teaming up with Philips lighting giant to produce glowing LED carpets. The big idea is to create safer walkways and exits, but there’s also a major that’s-just-cool factor to it. Desso is worth learning about because its mission is to only design products that are 100 percent biodegradable or can be entirely recycled for new products.
