## Abstract

On February 11, 2019, the U.S. Department of Energy (DOE) published a notice of proposed rulemaking (NOPR) proposing to withdraw 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. DOE responds to comments received on the NOPR in this final rule and maintains the existing regulatory definitions of GSL and GSIL, which are the same as the statutory definitions of those terms.
