I'm no expert by any means, but maybe check out these delta lne drivers on arrow for just under $20 a piece.

I like the idea of being able to adjust both the Vo and Io to give a little more of a "safety" wiring them in parallel since you can limit the voltage in case one board went down. Four of these drivers would cost just a little more than one hlg-240-36 driver and would give you a bit more flexability in the long run since you would be able to pair up two boards to a single driver.
Again just to reiterate, I am no expert and this is just my thought process if I had 8 of these boards to play with.
Thanks for your input.
Those drivers are $71 CAD at mouser, a comparable (or better?) meanwell driver 'hlg-120h-36' is $74 CAD. So it's no real difference. A hlg-240 driver is $95 CAD, a hlg-320 is about $125 CAD, so it's gets cheaper with wattage increase. But I don't want more than 4 boards per driver, really. And 2 per driver would be considerably more expensive.
I'm not familiar with those delta drivers at all, cool.
Vo and Io is nice to have, but I wan't remote dimming options, and dim-to-off - or at least dim to 10%.
Yea, I like the CV drivers for that reason; you can add and remove boards at will (within specs/reason).
I'm going to assume you meant QB 132's.
The HLG-xxxH-36B, will work fine but, if you every plan to repurpose the driver, a constant current driver would have more options.
If you think there is a chance you might run 5 boards in the future get the hlg-320h-c1750b. If budget is tight or your pretty sure this driver will stay married to these boards, save a little money and get the hlg-240h-c1750b. My personal preference would be the hlg-320h-c2100b, because of the possible repurposing options.
If you plan on running your boards much over 1750mA, then the hlg-320h-c2100b is your only option.
Without using a controller like an arduino, there is no simple way to control the dimming of the lights as you described. You can have one potentiometer control both drivers, or two potentiometers, each controlling one driver.
As far as "left over" voltage or current, there is none per se. It's more a case of unused potential.
Yea, qb132. I confused the model with the price.
Ok, I kinda see what you mean. Though, I haven't messed with series-parallel or anything like that. I've like CV drivers so far due to the ability of adding or removing one or more of the
same board with ease.
I think the only reason I'd run an odd number like 5 would be if splitting 10 in half with two drivers, or some other specific setup/fixture. I like even numbers; pairs of two. When you say repurposing options, could you give me an example please?
Well, it's just that the qb132s, are rated up to 2000mA, so I wanted to have that capability "on tap" so to speak, with the driver.
Maybe I wasn't clear about dimming/pots. I mean: the drivers have dimmer leads, you can connect up to 4 of those to a single rapidled pot. So, 2 drivers of the same power on one dimmer, for example. They'll be dimmed evenly with one pot. But you can just disconnect one driver from the wago and connect it to it's own (second) rapidled pot, and now you have to separate halves/drivers both on their own dimmers, in seconds, if needed.
edit:
I have a couple hlg-240h-c2100 drivers, see. And initially, from memory, I was thinking that the qb132 was rated at 2100mA or a bit higher. I thought perfect, I could probably run four qb132 of one hlg-240h-c2100, but they only have enough voltage for three boards, and on top of that, they'd be a little bit overpowering (amperage) the boards...?
Yea.
edit2:
correction on the voltage range of the hlg-320h-c2100 that I posted; it's "76-
152v", not "76-
162v"
