California has become the first state to set energy standards for household LEDs and track-lighting bulbs — a move that could save consumers billions in utility bills and prompt nationwide adoption of the requirements.

The California Energy Commission on Wednesday approved standards for energy efficiency, color and minimum lifetime for general purpose light-emitting diodes — the kind used in household lamps. Requirements also were set for directional lamps of about 2 inches or smaller.

Bulbs sold in California must meet the standards as of 2018.

LEDs last far longer than incandescent or halogen bulbs, but they cost more. So consumers have been slower to adopt them.

The commission says the energy-efficient, longer-lasting bulbs could save Californians $4 billion in utility costs and conserve enough electricity to power 400,000 homes.
