Late last month, the U.S. Environmental Protection Agency (EPA) released the first draft of a proposed revision to the current ENERGY STAR product specification for lamps (light bulbs). The EPA hopes to continue the market transformation of efficient lighting by incorporating spec changes that allow expanded product selection and increased production flexibility.

Key changes proposed for the new version include:

  • 15,000 hour lifetime for all lamps – The proposal reduces the minimum lifetime requirement of directional lamps (currently 25,000 hours) to align with the current lifetime requirement of 15,000 hours for non-directional lamps. The goal is to encourage lamp manufacturers to qualify more of their product families to ENERGY STAR performance requirements, broadening the availability of lower cost, and high quality products to consumers.
  • LED packaging as an allowable variation for family grouping – This will allow new lamps, based on certified products but in a modified package, to undergo a quicker, more limited testing and certification process.
  • New light flicker test method1 – The EPA is proposing a new test method to predict if consumers will perceive flicker with ENERGY STAR certified dimmable lamps.

Other updates include references to the Department of Energy’s lamp test procedures, clarification of noise measurement for dimmable lamps, and the addition of a filament style LED lamp definition.
