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:

1. For incandescent and incandescent reflector lamps: 10CFR 430.23(r).
2. For medium base compact fluorescent lamps: 10CFR 430.23(w).
3. For general service fluorescent lamps: 10CFR 430.23(r).
4. For fluorescent lamps that are not Medium base compact fluorescent lamps and general service fluorescent lamps: IES LM-9.
5. For LED light sources, IES LM-79.
6. For high intensity discharge lamps, IES LM-51.
7. For induction lamps, IES LM-66.

The reported value shall be the minimum luminous efficacy of the tested units and be rounded to the nearest tenth.

Power factor shall be measured at full light output in accordance with ANSI C82.77, Section 6 and 7.

For lamps, the reported value shall be the average measured values of the tested units rounded to be the nearest tenth.

For all other sources, the reported value shall be the minimum power factor of the tested units rounded to the nearest tenth.

Start time shall be measured in accordance with the ENERGY STAR Program Requirements Product Specifications for Lamps 2.1: Start Time Test Method, notwithstanding the scope of the test, subject to the following modifications:

For lamps the reported value shall be the average start time of the tested units rounded to the nearest millisecond.

For all other light sources the reported value shall be the maximum start time of the tested units rounded to the nearest millisecond.

For light sources that provide a fade-in feature, the initial plateau shall be the point specified in the U.S. Environmental Protection Agency ENERGY STAR Program Requirements for Lamps and Luminaires Start Time Test Method dated October 2017.

For light sources with a standby mode consuming no more than 0.2 watts of power, the start time test may be performed with the product receiving power and in this mode. In this case, the start time shall be the time between the sending of an on signal to the device via an appropriate control and the initial plateau.

Correlated Color Temperature (CCT) and Color Rendering Index of federally-regulated light sources shall be determined by the test procedures specified in 10 CFR 429 Subpart B and 10 CFR 430.23(gg).

Correlated Color Temperature (CCT) and Color Rendering Index of non-federally-regulated light sources shall be determined by the following test procedures, as applicable to the type of light source:

1. Incandescent and halogen reflector lamps: IES LM-20.
2. Incandescent non-reflector lamps: IES LM-45.
3. Single ended compact fluorescent lamps: IES LM-66.
4. Fluorescent lamps that are not single ended compact fluorescent lamps: IES LM-9.
5. Induction lamps: IES LM-66.
6. LED light sources: IES LM 79.
7. High intensity discharge lamps: IES LM-51.
8. Other equipment: other applicable test procedure approved by the Executive Director

Nominal Correlated Color Temperature (CCT) shall be calculated in accordance with CIE 15 (reference document ANSI C78.377). Color Rendering Index (CRI) shall be calculated in accordance with CIE 13.3.

The reported value shall be the average measured values of units tested rounded to be the nearest whole number for CRI.

Light sources shall be tested for flicker using Joint Appendix 10.

The audible noise test shall be performed as specified in the ENERGY STAR Program Requirements Product Specification for Lamps Version 2.1: Test Method – Noise, notwithstanding scope.

Minimum dimming level is measured by comparing the stabilized light output of the light source with the dimming control set to full light output with the dimming control being set to the manufacturer’s minimum rated output. Full light output and minimum light output is measured after the light output has stabilized according to the test procedures specific to light source type in Section JA8.3.1.

In addition to the reporting of flicker results as described in Section JA8.6, flicker test data for each combination of light source, ballast or driver (if applicable), transformer type and dimmer type claiming compliance with JA8 shall be submitted to the California Energy Commission.

Testing for minimum dimming level, flicker, and audible noise is required for each combination of light source, ballast or driver (if applicable), transformer type and dimmer type as follows:

1. Low voltage light sources shall be tested with a representative transformer for each transformer type that the light source is claiming compatibility.
2. Light sources claimed as compatible with forward phase-cut dimmers shall be tested in combination with a NEMA SSL 7A compliant dimmer.
3. Light sources claimed as compatible with dimmers other than forward phase-cut dimmers, dimmability, low noise and low flicker operation shall be tested for each ballast or driver combination (if applicable) with at least one representative dimmer for each dimmer type for which compatibility is claimed.
