JA8.4 Qualification Requirements
The following qualification requirements must be met for the light source to be considered High Efficacy as specified in Section 150.0(k) and Table 150.0-A.
JA8.4.1 Luminous Efficacy
The light source shall meet the following requirements when measured in accordance with the test method of Section JA8.3.1:
The luminous efficacy of the light source shall be equal to or greater than 45 lumens/Watt when tested at its full light output.
JA8.4.2 Power Factor
The light source shall meet the following requirements when measured in accordance with the test method of Section JA8.3.2:
The light source shall have a power factor equal to or greater than 0.90 when tested at its full light output.
JA8.4.3 Start Time
The light source shall meet the following requirements when measured in accordance with the test method of Section JA8.3.3:
The light source shall have a start time no greater than 0.5 seconds.
JA8.4.4 Color Characteristics
The light source shall meet the following CCT, Duv, and color rendering requirements when measured in accordance with the test method of Section JA8.3.4:
(a) Inseparable SSL luminaires, LED light engines, and GU24-based LED lamps shall be capable of providing a nominal Correlated Color Temperature (CCT) that is 4000 Kelvin or less and within 0.0033 Duv of the black body locus in the 1976 CIE color space.
(b) All other light sources shall be capable of providing a nominal Correlated Color Temperature (CCT) that is 3000 Kelvin or less and within 0.0033 Duv of the black body locus in the 1976 CIE color space.
(c) All light sources shall provide a Color Rendering Index (CRI) of 90 or higher and color rendering R9 value of 50 or higher when measured at a correlated color temperature and Duv value that comply with Section JA8.4.4.
JA8.4.5 Lumen Maintenance, Rated Life and Survival Rate
The light source shall meet the lumen maintenance, rated life, and survival rate criteria when measured in accordance with the test method of Section JA8.3.5 and JA8.3.6.
(a) Lumen Maintenance: The percentage of initial light output after the 6,000 hour test must be equal to or greater than 86.7 percent. For inseparable SSL luminaires referencing the in-situ measurement temperature of the LED, complying products shall have IES LM-80 test results that produce an IES TM-21 projected L70 of at least 25,000 hours.
(b) Rated Life: The light source shall have a minimum rated lifetime of 15,000 hours.
(c) Survival Rate: 90 percent of tested units shall be operational at the completion of the 6,000 hour life test.
Exception to Section JA8.4.6(c): Inseparable SSL luminaires referencing the in-situ measurement temperature of the LED.
JA8.4.6 Dimming, Reduced Flicker Operation and Audible Noise
The light source shall meet the following dimming, reduced flicker operation, and audible noise requirements when measured in accordance with the test method of Section JA8.3.7:
(a) The light source shall be dimmable down to 10 percent light output where 100 percent full light output is defined as operating the light source at the maximum setting provided by the control.
(b) LED-based light sources shall meet the requirements of NEMA standard SSL 7A as Type 1 or Type 2 products.
EXCEPTION to JA8.4.6(b): LED based light sources designed to be dimmed by controls other than forward phase cut dimmers.
(a) Light source in combination with specified control shall provide “reduced flicker operation” when tested at 100 percent and 20 percent of full light output, where reduced flicker operation is defined as having percent amplitude modulation (percent flicker) less than 30 percent at frequencies less than 200Hz, tested according to the requirements in Joint Appendix JA-10.
(b) Light source shall not emit audible noise above 24dBA measured at 1 meter from the light source when tested at 100 percent and 20 percent of full light output.
