Energy Department Announces Efficiency Standards for GSL Light Bulbs

Updated regulation for most common lightbulb type to go into effect July 2028.

This month, the Department of Energy (DOE) finalized its energy efficiency requirements for general service lamp (GSL) lightbulbs. These are the most common type of light bulbs used in homes and businesses in the U.S. 

This new standard, which will go into effect in July 2028, will require lightbulbs to emit more than 120 lumens per watt, significantly increasing the department’s previous standard of 45 lumens per watt. The DOE estimates that this change will help consumers save over $1.6 billion annually through reduced energy costs. 

“Making common household appliances more efficient is one of the most effective ways to slash energy costs and cut harmful carbon emissions,” said Secretary of Energy Jennifer 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.” 

As the Lord Leads, Pray with Us…

  • For Secretary Granholm and Energy Department officials as they seek to increase energy efficiency in consumer items.
  • For the president and members of his administration to be discerning as they pursue climate and energy goals.
