I actually ordered 4 of the QB96, but I want to run them at 220 watts. Can you recommend drivers? I'd either like 2 drivers running 2 lights at 220 watts each, or all four on a single driver with each one at at least 220 watts.
Also, are the aftermarket reflectors for the QB96 worth the 12$ each? Do they actually make a difference?
220w is a bit high unless you are actively cooling them with fans. I know it says 4200ma is the max with the heat sink but I’m running 2 per 320w driver and they get pretty damn hot at 100%.
I also think running them that hard is unnecessary. They are designed to cover a 2x2 area each, 30-40w per sq ft is the sweet spot for LED’s which is 120-160w. They are powerful and require a decent height above the canopy so running them harder will just require you to hang them even further away and they will be less efficient.
I would run all 4 of them on an HLG-600h-54a driver. That way if one goes out the other 3 can still safely handle the excess current.
I would pass on the reflectors. Not needed IMO.
