Developed in collaboration with the California Public Utilities Commission (CPUC), the California Energy Commission (CEC) has adopted a voluntary lighting quality specification for LED replacement lamps. The new standard requires that LED lamps meet certain performance criteria-such as light color, consistency of light output over time, and color rendering accuracy-to qualify for utility incentive programs and rebates. Dimming and flicker are also addressed in the specification requirements.

The original concept for this specification stemmed from research conducted by Michael Siminovitch and Konstantinos Papamichael of the California Lighting Technology Center. In turn, the CEC worked with technical experts, utilities, and industry entities to establish the performance level required for a lighting product to meet or exceed customer expectations for lighting in residential application. Residential lighting was selected as the focus because of this sector’s overwhelming use of incandescent lamps.

As the report’s abstract states, “This Voluntary California Quality LED Lamp Specification support[s] energy policy makers and the lighting industry in their collective goal to move consumers away from the inefficient incandescent lighting of the past century and toward more efficient light emitting diode (LED) lighting technology.” For more details go to:
