California Adopts First Energy Standards for Household LEDs

California became the first state to set energy efficiency standards for household LEDs and smaller track-lighting-style light bulbs — a move that could save consumers billions in utility bills and prompt lawmakers and manufacturers to adopt them nationwide. The California Energy Commission approved new requirements for general purpose light-emitting diodes — the LEDs used in household lamps and chandeliers — and directional lamps that have a diameter of 2.25 inches or less. They often are used in track lighting by stores, hotels and museums.
