I have a Meanwell HLG-240H-C2100B power supply (119v, 2.1a, CC, powered by 240v AC)
powering 3 Bridgelux Vero29 LEDin series. The output from the PS reads 115v, 2.1a = 241.5w.
Shouldn't the AC Watts "in" measure 258w? (241.5/.935=258)
I get a reading of 271w in - which suggests an efficiency of 89% not 93.5%.
Should I be checking the test equipment or is this difference to be expected?
