This lightbulb is officially the greenest replacement for a 60-watt bulb. It’s a light-emitting diode—commonly known as an LED—bulb made by the Dutch company Philips, it clocks in at under 10 watts, and it’s a bright, Big Bird yellow when it’s not illuminated. It also won its makers $10 million in the Department of Energy’s L Prize competition, which sought “high performance, energy-saving replacements” for the incandescents most of us still use. —via GOOD
