The ambient temperature condition inside the sphere was maintained at 25º C ± 1º C.The reference standard lamp is 100W omnidirectional Incandescent lamp and was calibrated by China Ceprei 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 1 nm intervals over the range of 380 to 780 nm.
