The US Department of Energy (DOE) published two final rules adopting revised definitions of general service lamp (GSL), general service incandescent lamp (GSIL) and other supplemental definitions, effective January 1, 2020 and is seeking public comment. DOE has since determined that the legal basis underlying those revisions misconstrued existing law. As a result, DOE is issuing this notice of proposed rulemaking (NOPR) proposing to withdraw the definitions established in the January 19, 2017, final rules.
DOE proposes to maintain the existing regulatory definitions of GSL and GSIL. This proposal would maintain the existing definitions of GSL and GSIL currently found in DOE's regulations, which are the same as the statutory definition of those terms. Specifically, the proposed withdrawal would maintain the statutory exclusions of specified lamps from the definition of GSIL, and thus, such lamps would not be GSLs.
