4 1.3 Test Facility The testing facility used by Bay Area Compliance Laboratories Corp. (Dongguan). is located at Pu Long Cun 69, Puxinghu Industrial Area, Tangxia Town, Dongguan, Guangdong, P.R.China. Bay Area Compliance Laboratories Corp. (Dongguan). is the International Accreditation Service (IAS) accredited laboratory. The IAS Lab Code is TL-460. Bay Area Compliance Laboratories Corp. (Dongguan) is recognized by EPA to test LED package, module or array (IES LM ) for the ENERGY STAR program. 1.4 Description of Auxiliary Equipment Device Manufacture Model No Serial No Test Range Integral Sphere Programmable Test Power for LEDs EVERFINE Diameter 0.3M nm, length:0.3m,0-1999lumen Calibration date Calibration due date EVERFINE LED300E V/2000mA Standard Light Source EVERFINE D N/A High accuracy array spectroradiometer 1.5 Operating Cycle EVERFINE HAAS T / Samples are driven with a constant direct current (DC) 1.6 Ambient conditions For lumen maintenance test, samples were operated in thermal chambers with minimal ambient airflow. for long term reliability test. The case temperature was controlled by 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 1.5 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=1.50% (K=2), at the 95% confidence level. The uncertainty of the correlated color temperature measurements is U=14K (K=2), at the 95% confidence level. This calibration results traceable to the NATIONAL INSTITUTE OF METROLOGY (NIM).
