The following qualification requirements must be met for the light source to be considered High Luminous Efficacy as specified in Section 150(k) and Table 150.0-A.
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 either the applicable State or federal appliance efficiency standard or 45 lumens/Watt, whichever is higher, when tested at its full light output.
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.
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.
The light source shall meet the following CCT and color rendering requirements when measured in accordance with the test method of Section JA8.3.4:
- All other light sources shall provide a Color Rendering Index (CRI) of 90 or higher and color rendering R9 value of 50 or higher.
- All light sources shall be capable of providing a nominal Correlated Color Temperature (CCT) of 4000 Kelvin or less.
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:
- 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.
- LED-based light sources designed to be connected with or dimmed by forward phase cut dimmers shall meet the requirements of NEMA standard SSL 7A.
- Light source in combination with specified control shall provide “reduced flicker operation” when tested at full light output as specified in JA10, where reduced flicker operation is defined as having percent amplitude modulation (percent flicker) less than 30 percent at frequencies less than 200Hz.
- Light source shall not emit audible noise above 24dBA measured at 1 meter from the light source when tested at full light output.
- Light sources shall also be tested and shown to comply with (c) and (d) while at 20% light output.
