Energy Conservation Program: Clarification of Test Procedures for Fluorescent Lamps Ballasts

On November 4, 2015, the U.S. Department of Energy (DOE) issued a notice of proposed rulemaking (NOPR) to clarify the test procedures for fluorescent lamp ballasts. That proposed rulemaking serves as the basis for the final rule. DOE is issuing a final rule to replace all instances of ballast efficacy factor (BEF) with ballast luminous efficiency (BLE) in its regulations concerning fluorescent lamps ballasts and to add rounding instructions to the same section for BLE and power factor. DOE is also clarifying the represented value instructions for power factor. Finally, DOE is amending Appendix Q to clarify the lamp-ballast pairings for testing.
