Need Advice with a DIY mixed LED layout for a 4X4

Hi all :)

I could really use some help with the layout of a new light fixture I am putting together please.
Rather than go out and get more lights etc, I really would like to use some spare lights I have had laying around for far too long. My selection I have

2x HLG QB96 V2
1 x HLG-320H-C2800A

4x Samsung F-SERIES GEN3 3500K STRIPS
1x HLG-320H-48A

The strips wont be powered at more than 250w across all 4, the HLG's will be run at the full 320w for a total of more or less 570w across a 4x4 space (half of my 8x4 tent)

My main concern with my design is hot spots, and potentially different height requirements for each LED type. The HLG's alone wont do well enough for my needs in this space, so I figured the strips on the outskirts would do well to keep the PAR levels up where its needed.

In short - anyone got any layout suggestions, to make better use of these LEDs? I have not purchased the frame yet, which I make out of T-Slot aluminum (PG30) so still flexible on that.

I don't know. With those 96's you're going to be hanging for spread, so might be worth it, to give yourself some elbow room and pull the strips inward. As it is 100mm from tent side to strip seems tight.

Thanks for the reply,

Yeah I think you are right, its a bit tight up against the walls - will bring it in maybe another 50mm each side (900mm span)?

I'd bite the bullet and get 2 more 96s so you can corner them and split the current to 80w a piece. Then you can run your strips in the middle for your main spread. Corners need to be higher wattage for even spread which me and @fragileassassin have recently found out
