U.S. Department of Energy (DOE) has announced an update to its energy conservation standards for general service lamps marking a significant leap in minimum efficacy requirements for lighting. The new regulations, known as the final rule, mandate that all general service lamps must achieve at least 83.3 lumens per watt for the most common lamps, a stark rise from the current standard of 45 lumens per watt.

The revised standards are part of the DOE's ongoing efforts under the Energy Policy and Conservation Act (EPCA), which mandates regular updates to ensure that energy conservation standards for consumer products remain in step with technological advancements. The new rule stipulates that all general service lamps manufactured in or imported into the U.S. must meet these heightened efficacy criteria starting on July 25,2028.
