For long term reliability test, the case temperature was controlled by mounting several thermocouples on a sample reliability stress board at the designated thermal measurement point, as shown in APPENDIX. The ambient temperature T A was measured by several thermocouples at a distance of 5 mm above the reliability test board. The relative humidity within chamber was less than 65%. For photometry measurement, temperature was set to 25 C ± 2 C, RH <65%. 1.7 Photometry Measurement Uncertainty The uncertainty of the light output measurements is U=1.59% (K=2), at the 95% confidence level. The uncertainty of the correlated color temperature measurements is U=21K (K=2), at the 95% confidence level. This calibration results traceable to the NATIONAL INSTITUTE OF METROLOGY (NIM).

14 1.8 Sample Set Sampling Method: LED samples for IESNA LM-80 testing consist of units built from a minimum of three manufacturing lots with each manufacturing lot built from different wafer lots built on non-consecutive days. These manufacturing lots are picked to represent a wide parametric distribution. Each Sample is soldered to all of the reliability stress boards for a given set of IESNA LM-80 tests. Sample Size: Total 30Pcs; Each Ts test condition 15Pcs The samples tested at Ts 85 C and TS 105 C were received at and tested during to The samples were numbered from 1to 15 and 16 to 30.
