Energy Conservation Program: Test Procedures for Fluorescent Lamp Ballasts

On October 21, 2014, the U.S. Department of Energy (DOE) issued a notice of proposed rulemaking (NOPR) to amend the test procedures for fluorescent lamp ballasts. That NOPR serves as the basis for this action. This final rule amends DOE's regulations concerning the test procedures for the measurement of energy consumption for fluorescent lamp ballasts. Specifically, these amendments clarify the requirement to use the test procedures in Appendix Q1 to demonstrate compliance with the energy conservation standards that apply to fluorescent lamp ballasts manufactured on or after November 14, 2014. These revisions follow the intent of the fluorescent lamp ballast test procedure final rule to support any new or revised energy conservation standards at the time those standards require compliance. This final rule also corrects the formula for power factor, which contained a mathematical error as adopted in that final rule.
