b) Omnidirectional lamps labeled “not for use in enclosed fixtures” on the lamp ;
c) LED light engines and lamps labeled “not for use in recessed fixtures” on the product ; and
d) Inseparable SSL luminaire: Alternatively inseparable SSL luminaires may reference the in-situ measurement temperature of the LED, IES LM80 test results and TM21 projections for the light source used in the luminaire.
(j)
For lamps the reported value shall be the 9th highest measured lumen maintenance value measured (9 out of 10 units must pass life testing).
For all other sources (except those using the IES-LM80 test method and the IES-TM21 calculation method for projecting lumen maintenance) the reported value shall be the minimum measured lumen maintenance value of the 3 samples.
(k)
Inseparable SSL luminaires designed to be recessed, shall be ICAT (insulation contact air tight) rated in accordance with Section 150.0(k)1C and tested with sides and top of luminaire in direct contact of least 12" of R-38 fiberglass insulation.
For inseparable SSL luminaires referencing the in-situ measurement temperature of the LED, IES -LM80 test results and projecting lumen maintenance using the IES-TM21 calculation method for the light source used in the luminaire, ten samples for each TS and drive current combination (refer to IES TM-21, section 4.2) must be tested. Each sample set may be composed entirely of one nominal CCT, or may be split between no more than two adjacent nominal CCT values as outlined in ANSI C78.377 (e.g. 2700 and 3000K). Passing Test: all of the conditions below shall be met.
1. In the sample luminaire, the in situ TMPLED temperature is less than or equal to the temperature specified in the LM-80 test report for the corresponding or higher drive current, within the manufacturer’s specified operating current range.

JA8.3.7 Tests for Minimum Dimming Level, Flicker, and Audible Noise
The flicker test is performed for light sources as specified in Joint Appendix JA10 and the audible noise test as specified in the ENERGY STAR Program Requirements Product Specification for Lamps Version 1.1: Noise Recommended Practices, 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 JA 8.3.1.
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 in the format as defined in Joint Appendix JA10.
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.
