Finding different setups to play with HLG 320 and CXB 3590 36V on a 4x4.

Hey guys, I have a bunch of 320H 42B and a bunch of 3590s 36V.

I was wondering what configuration would be better for a 4x4.

I have CNC machinery so I can make pretty much any config when it comes to space between LEDS on a single piece of aluminium using passive or active heat sinks. I can mill the holes each LED and its heatsink would go in and make a square lamp or use bars.

I think 600W+ lamp would be the target here.

1 - What would be an ideal spread for the LEDS on a 4X4 matrix and how many per driver?

2- How many drivers should I use?

2- I have external dimmers on my drivers, at max I was shooting for 1200+ umoles per 4x4 block/lamp.

Can you suggest what would be the perfect setup using these parts?

I also have some 240H 42B laying around.

Thanks in advance for your help...

Just for the record, I tested two bars of 3x 3590s per HLG 320 on a 4x4 space.
Got descent numbers on my apogee... Not a great spread though.

there is no "ideal"

everything is a compromise in terms of cost vs. efficiency

Definitely going towards cost. I tend to build for my friends this setup. So cost is the most important. Using as less COBS as I can to achieve that. It is not my job, but all my friends want what i have build to test. And I don't want to build them something you think could be perfected. That is the purpose of this thread. I don't make money outta this.

As we have crazy import taxes in our country, less is MORE.

Another setup I was using for a 3x3 as two bars of 2x 3590 per 240 H 42.

I think 6x chips in a 2 foot square should light up a 4x4 pretty evenly at 16-18 inch height or so but it might be worth considering the par wattage difference running a lower current with more cobs. For instance, running 3 cobs on that driver will provide about 136 par watts. Running 4 cobs on the same driver will provide about 150 par watts. It's only 14 more, but for the same power use and will probably pay for itself the first run. Running 5 per driver will provide another 10-12 par watts for the same power so there are good reasons to use more cobs but like Bobby_G said it depends.

Thanks for the input. I'll do some tests.
