The purpose of this section is to assemble all of the 2013 Title 24 Standards language related residential LED lighting into one place in this chapter.
To qualify as high efficacy for compliance with the residential lighting Standards, an LED luminaire or light engine must be certified to the Energy Commission by the manufacturer.
LEDs not certified in accordance with all of the requirements in the Standards shall be classified as low efficacy, regardless of their actual efficacy.
There are no requirements, opportunities, or provisions to certify nonresidential LED luminaires to the Energy Commission. Any LED luminaires which are not for residential applications, and which may have been certified to the Energy Commission, have been done so incorrectly by the manufacturer.
The following Standards language establishes that manufacturers are responsible to certify high efficacy LED light sources
Residential high efficacy LED light sources are required to be Certified to the Energy Commission, which requires them to be certified by the manufacturer in a declaration, executed under penalty of perjury under the laws of the State of California, that all the information provided pursuant to the certification is true, complete, accurate and in compliance with all applicable provisions of Part 6; and if applicable that the equipment, product, or device was tested under the applicable test method specified in Part 6.
To qualify as high efficacy for compliance with the residential lighting Standards in §150.0(k), a residential LED luminaire or LED light engine shall be certified to the Energy Commission according to Reference Joint Appendix JA-8. LED lighting not certified to the Energy Commission shall be classified as low efficacy for compliance with §150.0(k). Nonresidential LED lighting is not required to be certified to the Energy Commission.
The following definitions in the Standards are relevant to the certification of high efficacy LED lighting sources.
Certified to the Energy Commission, means, when used in association with appliances, certified under §1606 of Title 20 of the California Code of Regulations; and otherwise means certified by the manufacturer in a declaration, executed under penalty of perjury under the laws of the State of California, that all the information provided pursuant to the certification is true, complete, accurate and in compliance with all applicable provisions of Part 6; and if applicable that the equipment, product, or device was tested under the applicable test method specified in Part 6.
Light Emitting Diode (LED) definitions used in Part 6 are in section 6.8 of ANSI/IES RP-16-10.
The following Standards language regulates how to classify luminaires as LED and how to determine input wattage.
Luminaires and luminaire housings manufactured with incandescent screw base sockets shall be classified only as incandescent. Field modifications, including hard wiring of an LED module, shall not be recognized as converting an incandescent luminaire or luminaire housing to a non-incandescent technology for compliance with Part 6.
§130.0(c)6B
Replacement of lamps in a luminaire manufactured or rated for use with linear fluorescent lamps, with linear lamps of a different technology such as linear LED lamps, shall not be recognized as converting the fluorescent luminaire to a different technology for compliance with Part 6.
§130.0(c)9
Light emitting diode (LED) Luminaires and LED Light Engine.
A. The wattage of such luminaires shall be the maximum rated input wattage of the system when tested in accordance with IES LM-79-08.
B. The maximum rated input wattage shall be labeled in accordance with §130.0(c)1. See section 6.4.1 of this chapter for additional information on luminaire labeling requirements.
C. An LED lamp, integrated or non-integrated type in accordance with the definition in ANSI/IES RP-16-2010, shall not be classified as a LED lighting system for compliance with Part 6. LED modules having screw-bases including screw based pig-tails, screw-based sockets, or screw-based adaptors shall not be recognized as a LED lighting system for compliance with Part 6.
D. Luminaires and luminaire housings equipped with screw-base sockets shall not be classified as a LED lighting system for compliance with Part 6.
E. Luminaires manufactured or rated for use with low-voltage incandescent lamps, into which have been installed LED modules or LED lamps, shall not be recognized as a LED lighting system for compliance with Part 6.
F. For LED lighting systems which allow the 'addition of luminaires or light engines without rewiring, the wattage of such luminaires shall be the maximum rated input wattage of the power supply, labeled in accordance with §130.0(c)1 or published in the power supply manufacturer’s catalog.
Table 150.0 - A
Table 150.0-A is shown as Table 6-1 in this chapter. According to Table 150.0-A, some of the lighting systems classified as residential high efficacy include the following:
1. GU-24 sockets rated for LED lamps.
2. Luminaires using LED light sources which have been certified to the Commission as high efficacy in accordance with Reference Joint Appendix JA8.
3. Luminaire housings rated by the manufacturer for use with only LED light engines.
Also, according to Table 150.0-A, lighting systems classified as residential low efficacy include:
1. Line-voltage lamp holders (sockets) capable of operating incandescent lamps of any type.
2. Low-voltage lamp holders capable of operating incandescent lamps of any type.
3. High efficacy lamps installed in low-efficacy luminaires, including screw base compact fluorescent and screw base LED lamps.
4. Track lighting or other flexible lighting system which allows the 'addition or relocation of luminaires without altering the wiring of the system.
5. Luminaires using LED light sources which have not been certified by the manufacturer to the Commission as high efficacy.
6. Lighting systems which have modular components that allow conversion between high-efficacy and low-efficacy lighting without changing the luminaires’ housing or wiring.
Following is the language from Reference Joint Appendix JA8, which is required by manufacturers to qualify LEDs as residential high efficacy.
Reference Joint Appendix JA8
To qualify as a residential high efficacy luminaire using Light Emitting Diode (LED) as the light source (as defined in IES LM-80-2008), the LED light engine (as defined in ANSI/IES RP-16-2010) used in the luminaire shall be certified to the Energy Commission according to all of the following requirements, or by a method approved by the Executive Director.
If the LED light engine is inseparable from the luminaire (integral LED luminaire) then the entire luminaire shall meet the same requirements. LED light engine(s) and integral LED luminaire(s) are referred to as LED luminaire(s) below.
a. Shall be manufactured for use in residential applications.
LED luminaires not intended for use in residential applications, LED landscape luminaires, and luminaire housings not containing a light engine shall not be certified to the Energy Commission for the purpose of complying with Joint Appendix JA-8.

c. When designed or rated for indoor use shall be capable of providing a nominal Correlated Color Temperature (CCT) that includes at least one point within the range of 2700K to 4000K;
When designed or rated for outdoor use shall be capable of providing a nominal CCT that includes at least one point within the range of 2700K to 5000K. (With tolerance defined as in ANSI C78-377-2008)
Exception to subsection (c): Monochromatic LEDs that are only for decorative purposes
d. Shall be capable of providing a minimum Color Rendering Index (CRI) of 90.
Exception 1 to subsection (d): Monochromatic LEDs that are only for decorative purposes.
