Energy Conservation Program: Test Procedures for Integrated Light-Emitting Diode Lamps

This supplemental notice of proposed rulemaking (SNOPR) proposes a test procedure for light-emitting diode (LED) lamps (hereafter referred to as LED lamps) to support the implementation of labeling provisions by the Federal Trade Commission (FTC), as well as the ongoing general service lamps rulemaking, which includes LED lamps. The SNOPR proposes test procedures for determining the lumen output, input power, lamp efficacy, correlated color temperature (CCT), color rendering index (CRI), power factor, lifetime, and standby mode power for LED lamps. The SNOPR also proposes a definition for time to failure to support the definition of lifetime. This SNOPR revises the previous proposed test procedures for LED lamps by referencing two recently published industry standards that describe a process for taking lumen maintenance measurements and projecting those measurements for use in the lifetime test method.
