The U.S. Department of Energy (DOE) has issued a pre-publication Federal Register notice of proposed rulemaking (NOPR) pertaining to test procedures for general service lamps (GSLs) proposing several clarifications. Specifically, DOE proposes:
- to clarify that GSLs must not be tested as colored lamps,
- GSLs that can operate at multiple correlated color temperatures (CCTs) be tested at one specific CCT, and
- that lamps with additional components that do not affect light output must be turned off during testing.
The proposed clarifications specify that non-integrated lamps be tested with a fluorescent lamp ballast or external driver selected based on compatibility lists and availability; and provide specifications regarding the starting method, ballast factor, number of lamps and references to the relevant industry standards.
