## 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 either the applicable State or federal appliance efficiency standard or 45 lumens/Watt, whichever is higher, 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 and color rendering requirements when measured in accordance with the test method of Section JA8.3.4:

(a) LED lamps regulated by the Title 20 Appliance Efficiency Regulations and subject to Color Rendering Index requirements under Title 20 shall comply with the Color Rendering Index requirements in Title 20.

(b) All other light sources shall provide a Color Rendering Index (CRI) of 90 or higher and color rendering R9 value of 50 or higher.

(c) All light sources shall be capable of providing a nominal Correlated Color Temperature (CCT) of 4000 Kelvin or less.

### 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 shall either be 86.7 percent after 6,000 hours or 93.1 percent after 3,000 hours, based on whether the product is reporting final or interim test data. Light sources tested using LM-80 and TM-21, as specified in the ENERGY STAR product specifications, may use the ENERGY STAR TM-21 calculator to determine lumen maintenance at 3,000 or 6,000 hours.

(b) Rated Life: The light source shall have a minimum rated lifetime of 15,000 hours.

(c) Survival Rate: For tests using a sample group of ten units, 90 percent of tested units shall be operational for the duration of the test. For tests using a sample size less than ten, all tested units shall be operational for the duration of the test.

Exception to Section JA8.4.6(c): For products reporting interim test data, the survival rate must be met at the time the interim data is recorded.

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 designed to be connected with or dimmed by forward phase cut dimmers shall meet the requirements of NEMA standard SSL 7A.

(c) 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.

(d) Light source shall not emit audible noise above 24dBA measured at 1 meter from the light source when tested at full light output.

e) Light sources shall also be tested and shown to comply with (c) and (d) while at 20% light output.
