TEST REPORT
Report # 20130325JR-LM79
Test Results –
The following results were obtained after stabilization of the sample in accordance with the requirements set forth
in section 5.0 of IES LM79-2008. Stability is achieved when the variation of 3 readings of light output and electrical
power over a period of 30 minutes, taken 15 minutes apart, is less than 0.5%.
