First grow, lots of things to learn and figure out. These are purple kush seedlings in 60/40 Canna coco/perlite, inside a Sunblaster nanodome with an 18" T5 (17watts). For the first 10 days, they only received distilled water ( ph 5.8 ) On day 10, they got their first feeding with Canna Start...

Anyone know the efficiency of the CLU058-1825 COB at 120w? I'm assuming it's below 50%. I've also noticed the light engine with this COB comes with a LEDiL Angelina reflector, however I can't seem to find a part number that is designed for the CLU058. Is the CobKits light engine using a...

The same spec sheet seems to cover all versions; A, B and blank. Seeing that people run these drivers at max load makes me feel better, I'm still waiting for mine to run some tests, but if keeping Tc at a reasonable level isn't difficult (I can put a fan on the driver as well), max load...

I plan to power four CLU058-1825's with one driver. 100% load would give me 150watts (max 54V) each, 80% load = 120watts... These COBs can handle that easy, I'm just worried about driving the power supply at 100%.

Meanwell told me that running my drivers (HLG-600H-54B) at 90~100% will reduce lifetime from the expected 62K hours down to about 20K hours and if Tcase temps go above 75deg C, the 7 year warranty is void. I guess the question is, what kind of Tcase temps can I expect at any given load at room...

Does anyone actually run their HLG drivers at 100% load? Or do you all keep it to the recommended max of 80% load?
