Administration Finalizes Light Bulb Rules: 120 LpW

WASHINGTON, D.C. — The U.S. Department of Energy (DOE) today finalized Congressionally-mandated energy efficiency standards for general service lamps (GSLs), which include the most common types of residential and commercial lightbulbs. These standards— which will go into effect in July of 2028 for newly produced bulbs—are expected to save American families $1.6 billion annually on household energy costs, significantly cut energy waste, and slash harmful greenhouse gas pollution. Over 30 years, DOE projects these updated standards will save Americans more than $27 billion on their utility bills and cut 70 million metric tons of dangerous carbon dioxide emissions—equivalent to the combined annual emissions of over 9 million homes. Today’s announcement represents the Biden-Harris Administration’s latest steps in delivering savings through appliance efficiency, as directed by Congress.

“Making common household appliances more efficient is one of the most effective ways to slash energy costs and cut harmful carbon emissions,” said U.S. Secretary of Energy Jennifer M. Granholm. “Under President Biden and as directed by Congress, DOE is following the lead of lightbulb manufacturers, helping American families flip the switch on massive energy savings through strengthened energy efficiency standards.”

DOE continues to carry out Congressional direction for energy savings that maintain reliability and performance across household appliances and commercial and industrial equipment. Today’s actions are part of a suite of energy efficiency standards advanced by the Biden-Harris Administration this term that DOE projects will together provide nearly $1 trillion in consumer savings over 30 years and save the average family at least $100 a year through lower utility bills. DOE also estimates that the full set of standards, once finalized, will cumulatively reduce greenhouse gas emissions by 2.5 billion metric tons or more—an amount roughly equivalent to the emissions of 18 million gas-powered cars, 22 coal-fired power plants, or 10.5 million homes over 30 years.

These actions reinforce the trajectory of consumer savings that form a key pillar of President Biden’s Investing in America agenda. They also highlight the opportunities to lower costs for American families and businesses in ways that also cut climate pollution.

General Service Lamps 
Today’s final rule will raise the efficiency level from 45 lumens per watt to more than 120 lumens per watt for the most common lightbulbs, in line with the ongoing transition toward more efficient and long-lasting LED bulbs that the lighting industry and consumers are already embracing. Manufacturer compliance with the efficiency standards being adopted today will be required from July 25, 2028, and will apply to newly produced or imported general service lamps—not affecting continued consumer use and purchase of bulbs already manufactured. The energy savings from these standards over 30 years of shipments is approximately 4 quadrillion British thermal units, which represents a savings of 17% relative to the status quo of lightbulb energy use.

DOE already implemented minimum lightbulb efficiency levels that were specifically directed by Congress in the bipartisan Energy Independence and Security Act of 2007, which set levels that cannot be met by energy-inefficient incandescent bulbs. Today’s standards—which reflect Congressional direction for DOE to regularly review efficiency standards to ensure consumers benefit from technological advances that provide savings—set efficiency levels that can be met by a broad variety of widely available LED bulbs but not by compact fluorescent bulbs (CFLs), which the market is already transitioning away from. LEDs provide longer lifespans and lower electricity usage, and unlike CFLs do not contain mercury.

Lowering Energy Costs for American Families and Businesses
