Are you talking aboput (Logic) growmau5's design. or Chiled's?
Or QB's with Samsungs?

You have COBs with a 36.6 voltage.
Well, that's what I found after a copy/paste of the part #.
We're going to need more information to get that driver question answered properly.
Let us begin.
What do you have for heatsinks?
2 x Meanwell xlg240-h-ab should work great aswell with a little less $$$My cobs are 90cri, 1800mA; 52V; 93,6W (I found this info on its catalog).
About heatsinks: I live in Brazil, which doesn't have a good passive heatsinks market, so I already bought six Alpine 11 GT coolers.
My initial idea was to use HLG-480H-54A. But now, with the high of dollar I've been thinking in another alternative.
2 x Meanwell xlg240-h-ab should work great aswell with a little less $$$
Yes it should work, but at around 50w each cob.
The more cobs per driver the better, running soft will increase efficiency.
Dont know, i usually dont use fuses.Do I have to assemble the three cobs by making parallel connections, right? In this case, one fuse per cob would give me the necessary security?
How can I choose the fuses?
