3.0 LM-79 Measurement and Test Results 3. Integrating Sphere Test for the lower CCT Model No. BLHE-62DU50 Sample ID. 628446-002 Opreate time Stabilization Driver No. N/A 80 70 (Min.) time (Min.) Test Method.The sample was tested according to the IES LM-79-2008. 2.Photometric paramters were measured using an integrating sphere, a spectroradiometer and software. The ambient temperature condition inside the sphere was maintained at 25º C ± º C.The reference standard lamp is rated current 2.6A omni-directional Incandescent lamp and was calibrated by china seprei laboratory. 3.The sample measurements were made using a spectroradiometer connected by a fiber optic cable and detector through the detector port of the integrating sphere. Coating reflectance of the integrating sphere was 90% to 98%.Photometric measurement conditions was using 4π geometry.the self-absorption factor is applied in the final test result.the sample was operated at rated voltage and was stabilized before measurement. Chromaticity coordinates, correlated color temperature and color rendering index were calculated from the spectral radiant flux measurements taken at nm intervals over the range of 380 to 780 nm.

Sample ID. 80 628446-002 Stabilization time (Min.) 70 Test Method.The sample was tested according to the IES LM-79-2008. 2.Photometric paramters were measured using a type C goniophotometer and software. 3.The ambient temperature shall be maintained at 25 C ± C, measured at a point not more than m from the sample and at the same height as the sample.the reference standard lamp is rated current 3.865A omni-directional Incandescent lamp and was calibrated by china seprei laboratory. 4.The samples were operated at rated voltage and was stabilized before measurement. Luminous flux, luminaire efficacy, zonal lumen were calculated from the software taken at 0.5 vertical intervals and 22.5 horizontal intervals..photometric distance was more than five times of the largest dimension of the test SSL product.
