So 250w is the best way to run it?

The drivers maximum output is 250w,If you had a bigger driver you could get them up to 300w. There have been people that have used the HLG-320h-c2800 and that would give you the maximum capabilities of the boards. I am not sure if the QBv2 boards can go up to 150w. If they are the same 18x16 boards then I come up with 140w using HLG's data.
I adjust based on how much heat I need and I set height with a par meter if you run at 250 or more make sure you have a good heatsink and lots of airflow

I'll go ahead and order (2) hlg-240h-c2100a - One for each dual board. When it comes to the dimming capabilities, is the 'A' the one I should go for? Is it easy to wire up a remote dimmer so I dont have to mess with the driver directly?
The a series will go a little over Max if you unscrew the dimming screw all the way
I prefer using the a series and adjusting on the driver

OK. I was going to put the driver on the ceiling...I'll just find an alternate location.
Last question: Wire in series or parallel?
I always put my driver on the back of the heatsink I'll let someone else answer the series or parallel question series would be easiest with those boards and that driver I think. My boards are 100v so it's a little different for me

Yea I know, I'm using 2 of them and am only getting 550w so up to 275w from each fixture, using 1 QB v1 3000k and 1 QB v2 4000k
Shows 2.44A output
You using the 288 in series? I have the 304 in parallel

Yea, I have 4 of the boards, 2 each on an HLG-240h-c2100A. I guess I just assumed you were using one too
I have the same driver just 3 304 boards per driver

Oh yea I got ya, cause the boards need to be wired in parallel. How do you like that setup?
Yeah they are double the voltage so series won't work. I love it it's super overkill for the space but works great I have 9 boards per 4x4 it allows me to set the wattage at whatever I want an still have the spread to cover the space

Has anyone received Slate 2 heatsinks that are not drilled for the QB288? I just got a 2 board kit last week that I had to drill and tap holes in the proper places for the QB288's. The only holes that matched up to the boards were the two center ones. That was a bit of a pain. I hope that doesn't happen next time I order from HLG.

That's something to take in account, seeing as that I was about to get a double combo board this week...

Just to be clear, what I got was 2 boards with 2 single heatsinks. I don't know anything about the double length heatsinks. My guess is that the sinks I got were drilled and tapped for some other configuration. Maybe 304 or 324? There were more mounting holes than are on the QB288's.
