Last April, the U.S. Department of Energy (DOE) issued a Notice of Proposed Rulemaking (NOPR) for Test Procedures for LED Lamps. Since then, two supplemental notices (SNOPRs) have been published. Such rulemaking changes for test procedures could lay the groundwork for revisions to the country’s mandatory EISA efficiency requirements, which include lighting products sold in the U.S.
The initial NOPR addressed test procedures for the following metrics associated with lamps (light bulbs):
On June 3rd, the first SNOPR was issued. This revised the test procedure by supporting implementation of the Federal Trade Commission’s (FTC) labeling provisions and implementation of the DOE’s energy conservation standards for general service lamps. In addition, the June 3rd SNOPR included enhanced definitions for measuring lumen output, input power, relative spectral distribution, and for calculating lifetime. The SNOPR also added new calculations for lamp efficacy and color rendering index (CRI).
On June 26th a second SNOPR was issued, further defining calculations for determining lifetime and time to failure so that they better align with the U.S. Energy Policy and Conservation Act.
If the proposed test method changes are approved, other U.S. efficiency agencies such as ENERGY STAR will be required to use them in determining whether lamps comply with their requirements.
