Heatsink USA profile used here needs some airflow. Fins too close and not ideal for complete passive.

I have my room setup with 4ea) qb 288 & 4ea) qb 120's, and a 5 cob full spectrum fixture I built, I have a far red light bar that goes on at lights out for 20 min. I just added a solarcure fluorescent tube fixture for uvb. The room is 15 +- sq ft, 42" x 52". Also have a bunch of led tube fixtures on the walls for lower lighting.The whole ceiling is basically full but there is room to add 2 narrow fixtures, thinking about photo red but they would only be putting out 32w combined. Think this is even worth the effort, the components would cost about $148.00.
I think calling that overkill would be a bit modest.....lol! Great looking build!
What driver/s would run 4 qb 120s a just under 70w each max?
Hlg 320h-c2800? Im still super bad at driver selection.

HLG only gives one driver option for a 4 board set up in series. It's on the product page

Not correct. I have two 4xQB120 fixtures, each run off an HLG-240H-C2100A, and at 254w for one and 257w for the other, the drivers push the boards past HLG's recommended max of 60w per board.A 240-c2100 is under powered for 4 boards and went push them to full power.
The HLg-240h-C2100a will output near 2500ma per board in series.
The Hlg-240H-24A Will output near 2700ma per board in parallel.
Could I add 4 more qb120s onto the hlg-240h-24a (total of 8 ) if I want to up the efficiency down the road?
