I wanna take my driver from my saber150 and put it with my two qb272 boards is this possible? Current boards run with a hlg-150h-54 I like the 150w just want to dim it.IMG_0991.jpeg

If you're not going to listen to people, then please – don't ask.

If what you have is a 56V driver, it WILL work with those boards. The fact HLG assumed it was a 36V driver tells me they gave you the wrong answer – probably by accident. If you were to ask them again – and point out that it is a 56V driver – then you would get a different answer.

But in all honesty, it sounds like you don't really know what you're doing anyway, so you probably shouldn't be playing around with electricity to begin with.

So keep them wired in parallel like they are and just swap the driver?!View attachment 5345894
I will be attempting the swap tomorrow!!!
That type of parallel connection is not ideal, its daisy chained which means that even though they are in parallel the full current passes thru the right hand boards traces in order to get to the left board, which means it would heat up a bit more. Its doable but not ideal. Id get some wagos and route the current separately into each board.

From all info given yes, the driver in orginal post should work as long as all info is good. Looks like you have a constant power driver (afaik); these will work with anything between 22-56V. The sabre is 36 so hlg rep must have supposed that you used a 36V driver for your sabre. No way for him to know; always send a pic of the driver label (as you did here) when asking for help.

So ideally I would want to get a driver to run them in series.

Ohh I’ve seen diagrams where a set of positive and negative come from the driver. R those split with wago connections
Basicly 2x 3way wagos, one connects to + driver and 2 separate wires to + on boards, and same thing for the negatives. As it is now the 2 boards share the current but in order to get to the second board the current has to travel thru the first boards traces. This causes a bit extra heating up in the first board. But it isnt the biggest of deals in the world.
