The U.S. Department of Energy (DOE) has published a Federal Register notice re-evaluating its prior determination that the Secretary of Energy was not required to implement the statutory backstop requirement for general service lamps (GSLs).

Under the Energy Policy and Conservation Act, as amended, if DOE fails to complete a rulemaking in accordance with certain statutory criteria, or if a final rule for GSLs does not produce savings that are greater than or equal to the savings from a minimum efficacy standard of 45 lumens/W, the Secretary must prohibit the sale of any GSL that does not meet a minimum efficacy standard of 45 lumens/W.

This request for information (RFI) solicits information from the public regarding the availability of lamps that would satisfy a minimum efficacy standard of 45 lumens/W, as well other information that may be relevant to a possible implementation of the statutory backstop.

• DOE will accept comments, data, and information regarding this RFI until June 24, 2021.
• Interested persons may submit comments identified by docket number EERE–2021–BT–STD–0005, by email (, Federal eRulemaking portal, postal mail, or hand delivery/courier.
• Find product information for General Service Lamps including current standards and test procedures, statutory authority, waivers, exceptions and contact information.
