General Service Lamps (GSLs) include general service incandescent lamps (GSILs), compact fluorescent lamps (CFLs), general service light-emitting diode (LED) lamps, organic light-emitting diode (OLED) lamps, and any other lamps that are used to satisfy lighting applications traditionally served by GSILs. GSLs are used in general lighting applications and account for the majority of installed lighting in the residential sector.

Recent and Ongoing Activities

DOE has published a Federal register notice of proposed rulemaking (NOPR) pertaining to definitions for General Service Lamps (GSL). On January 19, 2017, DOE published two final rules adopting revised definitions of general service lamp (GSL) and general service incandescent lamp (GSIL), and other supplemental definitions, to go into effect January 1, 2020. Prior to that effective date, on September 5, 2019, DOE withdrew the revised definitions of GSL, GSIL, and the other supplemental definitions. Upon further review and consideration, in this  NOPR, DOE proposes to adopt the definitions of GSL and GSIL and the associated supplemental definitions set forth in the January 2017 final rules. This document also announces a public meeting to receive comment on these proposed definitions.

  • DOE will accept comments, data, and information regarding this NOPR until October 18, 2021.
  • Interested persons may submit comments identified by docket number EERE–2021–BT–STD-0012, by email ( or Federal eRulemaking portal ( 
  • The webinar will be held on Thursday, September 30, 2021, from 10:00 a.m. to 4:00 p.m.

DOE has published a Federal Register notice re-evaluating its prior determination that the Secretary of Energy (Secretary) 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 per watt (lm/W), the Secretary must prohibit the sale of any GSL that does not meet a minimum efficacy standard of 45 lm/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 lm/W, as well other information that may be relevant to a possible implementation of the statutory backstop. 


DOE has published a Federal Register notice withdrawing the revised definitions of general service lamp (GSL), general service incandescent lamp (GSIL) and other supplemental definitions, that were to go into effect on January 1, 2020.
