Graphene—everyone’s favorite super-strong carbon material—might just revolutionize the LED. A dimmable bulb is set to be launched in UK stores later this year that contains a filament-shaped LED that is coated in graphene, and promises to cut energy usage by a further 10 percent, sell at a lower price point than many LEDs, and all the while extend the life of the bulb. This all due to the fact that graphene can conduct heat and electricity more effectively than the materials currently used in LEDs. Designed by researchers at the “Home of Graphene,” The University of Manchester, the bulb will also be the first commercially-viable product to contain graphene.
