I'm running 4 qb120 in series with a Meanwell hlg-240h-c2100b driver. check the hlg site for the qb120, you can see driver recommendations/options at the bottom.
I've visit the driver recommendation page daily .Two Meanwell HLG-240H-C2100As for two 4xQB120 fixtures.
I don't get the 2x240. These driver run the boards @ 50w each, right? All 4 boards would fit on one driver. Why use 2 drivers? Is this a redundancy thing?
My other fixtures are all wired in series. I wanted to run the boards @ 60w and max out the driver so I decided to try out CV. hlg-240h-c2100b240-24B should be here by the weekend.
The real problem is getting the boards..
