480 W should be plenty for that space. If you wanna go with 600 w i recomend putting them on a alusheet, maybe glue or thermaltape some u-channels on top for more dissipation.
But for a similar price you can get 3 fotop boards, same dimensions, 800 lm561c diodes each and run them without heatsink. 480w would be plenty of light. You would have much lower temps and begter coverage and would be able to almost completely cover your cannopy with light. I recently setup 5 of those boards at 750w total/150w per board over something like a 6.5'x4' and was very happy with it. No heatsink and no heat. Very even coverage. Good par reading both close and further away.

What driver setup do you have for them? And how thick of an alu sheet do you recommend?

I cant tell you what driver to use on that board, you havent given any specs.

The boards i use are 48V, i have 5 in a 8 way wago so 3 spaces for drivers. I attach 48v drivers until i reach desired level. 750w on 5 boards was very good, but 3 drivers in the same wago made the light slightly flickery. I will get a hlg480-48A (or B) and add another hlg240-48 if need a bit more oomph.

Wait, are you saying you add/remove drivers in parallel to the same set of lights and they work happily together?

I'm aware that you can have more than one power supply in an electrical circuit but wondered if Meanwell's fault detection circuitry would trip up when used like this.

2 seemed to work without a problem, 3 and the lights was subtly flickering.

I found this site, https://www.keysight.com/main/editorial.jspx?cc=RO&lc=eng&ckey=520808&nid=-11143.0.00&id=520808 which states:

"The output voltage controls of one power supply should be set to the desired output voltage (CV); the other power supplies should be set for a slightly higher output voltage. The supplies with the higher output voltage setting will provide constant current output, and will drop their output voltage until it equals the output of the CV supply."

Have you tried playing with the voltage dimmers when you had 3 connected and blinking?

@Moflow what's the lowest power the boards would run at, thinking side lighting and plants possibly touching the leds. Im not for doing it but just curious.

I'm still undecided as to what driver to get for them..
I hooked them up this afternoon and had them at around 30 watts each which was nice and a single board at -70 watts.
Just a quick test.
I've a 900mm x 146mm heatsink that they fit on and can slot inbetween the FOTOPs, which is handy so there is lots of options. In that scenario a hlg 150h or 185h in parallel would probably suit.

She says I can't wire 3 of them in series on a HLG-600

You would be able to run them in parallel on an hlg 600h 48a. Think i'm about to pull the trigger on some qb 800s and be a guinea pig for these ali boards, hell that many diodes for that price is nice and no heat sink is a blessing. Heatsinks cost more than Led strips here in canada

Getting ready for the chop.
I de-fanned the SS Original and a Royal Gorrilla yesterday and will do the other RG today in prep for trim jail either lamarra or Thursday.

The Sensi reeks to high dough but not too much pong offa the RG's... or so I thought.....
My missus sez I'm just immune to smell and it and it stinks lol
Enjoy
