DOE Issues a Notice of Proposed Rulemaking on General Service Incandescent Lamps

The U.S. Department of Energy (DOE) has issued a pre-publication 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. Before that date, on September 5, 2019, DOE withdrew the revised definitions of GSL, GSIL, and the other supplemental definitions.

Upon further review and consideration, DOE now proposes to adopt the definitions of GSL and GSIL and the associated supplemental definitions set forth in the January 2017 final rules. This would effectively discontinue the regulatory exemptions for rough-service lamps; shatter-resistant lamps; three-way incandescent lamps; vibration-service lamps; reflector lamps; T-shape lamps of 40 W or less or length of 10 inches or more; and B, BA, CA, F, G16–1/2, G25, G30, S, M–14 lamps of 40 W or less.
