Lighting Sciences comments on test requirements for Energy Star for SSL
Jul 29, 2009
USA - The US Department of Energy (DOE) has issued Manufacturer Guidelines for qualifying both interior and exterior lighting products for the coveted Energy Star label. Very significantly, the program focuses on lighting quality as opposed to simple lumen output.
Marketable light quality in Energy Star for SSL is now defined by the photometric distribution, color characteristics, and efficacy of the lighting fixture. The reason for this focus on lighting quality is that a successful application of a lighting product will meet consumer’s expectations not just for lumen output, but for safety and comfort factors as well.
Procedurally, the DOE’s definition of light quality means to lighting product manufacturers that SSL products must be tested in both an Integrating Sphere and on a Moving Mirror Goniophotometer. The requirement that SSL fixtures be tested on a goniophotometer for intensity distribution represents an informed change in the DOE’s view on lighting products, which stems from its CALiPER program results.
Lighting Sciences facilitates Energy Star qualification for its clients by offering the most comprehensive photometric services in the industry, including tests for LM 79 and LM 80.
The DOE requires the following tests be performed by a CALiPER-approved laboratory:
Potentially required in the future:
