The California Advanced Homes Program (CAHP) scoring metric now allows participants to demonstrate improvement over the prescriptive lighting standards. The new high-efficacy lighting credit requires that all permanently installed lighting use high efficacy sources, such as LED or fluorescents, and no low efficacy sources such as incandescent or halogen.

This measure reflects the proposed revisions to the residential lighting requirements for the 2016 Standards, allowing LED screw-base lamps to be considered high efficacy, in addition to the other high efficacy lighting options defined in the current Standards. Homes installing all high-efficacy lighting receive 3 CAHP points, yielding a $300 to $600 incentive increase per home.


Screw-based LED lights must meet the following criteria from
the Voluntary California Quality LED Lamp Specification.
• ENERGY STAR® certified
• Color temperature between 2700K and 3000K
• Color Rendering Index (CRI) of at least 90, or higher
• Dimmable
