4 7. Drive current of the LED light source during Lumen maintenance test. See tables. 8. Initial luminous flux and forward voltage at photometric measurement current See tables. 9. Lumen maintenance for data for each individual light source along with median value, standard deviation, minimum and maximum lumen maintenance value for all of the light sources See tables. 10. Observation of LED light source failures including the failure conditions and time of failure No failures observed. 11. LED light source monitoring interval See tables 12. Photometric measurement uncertainty Flux measurement: 1.06% (k=2) 13. Chromaticity shift reported over the measurement time See tables. 14. Sampling Method/Sample size IES LM80 tests require LED samples to be operated at drive current 60mA, two temperatures of 55C and 85C. 40 pieces of LED samples are selected randomly from different production date of products. These samples are picked to represent a wide parametric distribution. Prepared by: Leading Testing Laboratories Page 4 of 11 Tel:
