Therefore, no seasoning was performed. Sphere-Spectroradiometer Method- Photometric and Electrical Measurements A Labsphere Model CDS 2100 Spectroradiometer and Two Meter Sphere was used to measure correlated color temperature, chromaticity coordinates, and the color rendering index for each SSL unit. The coating reflectance of each sphere is 98%. The measure geometry is 4π. Self-absorption correction is conducted in testing. Bandwidth of spectroradiometer is 350nm-1050nm. Ambient temperature was measured at a position inside the sphere. Each SSL unit was operated on the client provided driver at the rated input voltage in its designated orientation. The stabilization time typically ranges from 30 min (small integrated LED lamps) to 2 or more hours for large SSL luminaires). It can be judged that stability is reached when the variation (maximum minimum) of at least 3 readings of the light output and electrical power over a period of 30 min, taken 15 minutes apart, is less than 0.5 %. Electrical measurements including voltage, current, and power were measured using the Yokogawa Power Analyzer. The standard reference of the integrated sphere system is halogen incandescent lamp, the intensity distribution type is omni-directional, and is traceable to the National Institute of Standards and Technology. The uncertainty of integrating sphere system reported in this document is expended uncertainty is 1.06% with a coverage factor k=2. *** End of Report *** This report is considered invalidated without the Special Seal for Inspection of the LTL.
