DOE Again Revises Proposed LED Lamp Test Procedures

The Energy Department is making revisions to a proposed rule on energy efficiency test procedures for LED lamps that it issued earlier this month. DOE originally issued its proposed rule on LED lamps in 2012 to add tests that would support new Federal Trade Commission labeling requirements that had been set two years prior. In a supplemental notice of proposed rulemaking issued June 3, DOE amended its proposal to revise methods for calculating the lifetime of LED lamps, and add calculations for lamp efficacy and color rendering index. DOE is now again issuing a supplemental proposed rule, this time revising the June 3 rule’s proposed definition of “lifetime” and adding a new definition for "time to failure" in light of the revised definition of lifetime. Comments are due Aug. 4.
