In this rule, DOE withdraws the revised definitions of GSL and GSIL established in the January 2017 definition final rules which would otherwise take effect on January 1, 2020. These definitions included certain GSILs as GSLs in a manner that is not consistent with the best reading of the statute. Additionally, DOE withdraws the supplemental definitions established in 8 the January 2017 definition final rules that are no longer necessary in light of the withdrawal of the revised definitions of GSL and GSIL. This rule maintains 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 rule maintains the statutory exclusions of specified lamps from the definition of GSIL, and thus, such lamps would not be GSLs. DOE does not make a determination in this rule whether standards for GSLs, including GSILs, should be amended. Rather, this rule establishes the scope of lamps to be considered in that determination. DOE will make that determination in a separate rulemaking.

In the February 2019 NOPR, DOE proposed to retain the existing statutory exclusions from the GSIL definition by withdrawing the revised definition of GSL, which, among other lamps, included as GSILs the five specialty incandescent lamps regulated under 42 U.S.C. 6295(l)(4), namely rough service lamps, vibration service lamps, 3-way incandescent lamps, high lumen lamps and shatter-resistant lamps.
