"The Biden administration on Friday finalized lightbulb efficiency rules first proposed in late 2022.
The final rule will more than double the required efficiency level for the most common lightbulbs, from 45 lumens (the unit of measurement for light intensity) per watt to over 120 lumens per watt
The rule won praise from energy efficiency lobbying groups, with the American Council for an Energy-Efficient Economy’s (ACEEE) Appliance Standards Awareness Project (ASAP) citing Energy Department estimates that it will cut American utility bills by up to $27 billion while preventing the release of 70 million metric tons of carbon emissions over three decades."
