Joint Appendix JA8 provides the qualification requirements for high luminous efficacy light sources installed to comply with Section 150(k). For the purposes of this Section, high luminous efficacy light sources include ballasts or LED drivers if needed for operation of the light source: light sources shall be certified together with a driver or ballast. If the light source is inseparable from the luminaire the entire luminaire shall meet the requirements of this section. All qualifying light sources shall be certified to the Energy Commission according to all of the requirements in this Appendix.
The light source under test shall be tested at a testing laboratory accredited to ISO/IEC 17025:2017, by the National Voluntary Laboratory Accreditation Program (NVLAP) or other laboratory accreditation body operating in accordance with ISO/IEC 17011 and produced under an ongoing inspection program carried out by a Type A inspection body in accordance with ISO/IEC 17020.
Compliance with the requirements of this Appendix shall be determined by performance of the following test procedures, as applicable to the type of light source.
Sample group size shall be as specified in the referenced test procedures. Where a sample group is not specified for a test, a single unit shall be tested.
For federally regulated light sources, luminous efficacy shall be determined by the test procedures specified in 10 CFR 429 Subpart B and 10 CFR 430.23(gg).
For non-federally-regulated light sources, luminous efficacy at full light output shall be determined by the following test procedures, as applicable to the type of light source:
