California Adopts New Light Bulb Efficiency Standard

California is again showing the U.S. government and the world how to take bold steps to reduce greenhouse-gas emissions.

California Adopts New Light Bulb Efficiency Standard

On January 1 this year, California banned the sale of inefficient light bulbs. This action was needed because the Federal Department of Energy (DOE) was attempting to overturn the complete phase-out of inefficient light bulbs. The Energy Independence and Security Act (EISA), passed in 2007, laid out a 12-year plan to end the sale of energy-wasting incandescent and halogen bulbs and transition to dramatically more efficient alternatives. Per the law, the completion of this changeover was to take place on January 1, 2020.

This past fall, the DOE attacked the new standards by 1) deciding to keep the 2012 standards unchanged, and 2) withdrawing the updated efficiency definitions. These standards impact the bulbs that go into 2.7 billion lighting sockets in the U.S. Since these changes are illegal under the provision of EISA, the California Energy Commission (CEC) voted to adopt the higher efficiency federal draft regulations ​— ​the ones that the DOE is trying to eliminate. Thus, as of January 1, 2020, it is illegal to sell light bulbs in California that fail to meet the minimum efficiency standard of 45 lumens per watt. Lumens measure the amount of light delivered per watt of power consumed by a bulb.

There is a wide range of LED light bulbs that meet the new high efficiency standard. Replacing an old-fashioned 60-watt incandescent bulb with an LED of equivalent light output will use 10 watts of power or less. Moreover, the LED bulb will last at least 10 times longer, saving the cost and inconvenience of annual bulb replacement.
