ENERGY STAR's Lamp Program Revision Process Switches On

Mon, 04/13/2015 - 10:11 -- MrGreen

Recently, the U.S. Environmental Protection Agency (EPA) began the process of revising the current ENERGY STAR Lamp program specifications. It’s anticipated that the new version 2 specification will be completed in June of this year.

The program’s product scope is limited to lamp types that are intended to replace incandescent bulbs. Lamps must have integrated ballasts and drivers with rated nominal operating voltages of 120, 240, and 270 VAC, or 12 or 24 VAC or VDC. They should also conform to ANSI standard base types E26, E26d, E17, E11, E12, GU24, GU5.3, and GX5.3.

The version 2 proposal focuses on raising efficacy requirements, broadening the scope and features of newer technology lamps, utilizing the U.S. Department of Energy’s (DOE) proposed LED lamp test methods, and harmonizing with other ENERGY STAR lighting specifications. Included for the first time in any ENERGY STAR lighting program are requirements for connected lamps and color tunable lamps.

The EPA is proposing a single efficacy requirement for the three lamp types covered by the specification – directional, omnidirectional, and decorative.

Additionally, the EPA is proposing aligning with the requirements found in the first draft of the ENERGY STAR Luminaires version 2 specification (see Mr. Green blog EPA Shines Light On Luminaire Specification Revision) covering color rendering index (CRI), start time, run-up time, and correlated color temperature (CCT).

For a copy of the ENERGY STAR Lamp Program draft specification, EPA meeting presentations, and stakeholder comments, visit the ENERGY STAR lamp program webpage. A stakeholder meeting discussing the specification revisions to both the Luminaire program and Lamp program will be held in Washington, DC on April 20th.
