Ideal Way of Filling 6.5' x 6.5' Tent with Quantum Boards? 240w, 320w, or 480w Boards?

Hello, I have a 6.5' x 6.5' grow tent to dedicate to flowering. I am in the process of buying the lighting which I want to be quantum boards. I was wondering if i should fill the tent with 240 watt boards, 320 watt boards, or 480 watt boards? and how many?

I was originally thinking of doing four 480 watt boards for a total of 1920 watts. Spanned over 42.25 square feet gives me about 45 watts per square foot. From what I read on this forum 45 watts of QB is likely overkill so i'd probably have to dim it down?

If I were to do 320 watt boards I am thinking I could do four 320 watt boards for a total of 1280 watts and 30 watts per square feet

If i were to do 240w boards I am thinking I could do eight boards for a total of 1920 watts which gives me 45 watts per square foot. So again, I'd probably dim the lights down in the tent.

I could also consider doing 6 320-watt boards (45 watts per sq ft) or 6 240-watt boards in the tent (34 watts per sq ft). In a square 6.5' tent would I be better off doing multiples of four with my lights to try to get an even coverage footprint though?

Would appreciate any feedback, tips, and advice! Thanks in advance!

It depends. Are you gonna pack the tent. Like literally no entry? Or you gonna leave an aisle you can crawl in?? How you arrange your light kind of depends on how you plant to grow.

I used to put my 4x8 tents up against two walls so I could lean on and post my arm in the wall while I watered the very back rows. I had that tent rammed door to door.

and if the price isn't much different 6x240s is good so you can spread how you want. Also 34W/sqft is with no CO2.
Edit: also that size of tent and watts you are gonna be spending like 5-6000 BTU in there. So careful with heat I hope you are planning a strong exhaust to outside or an AC or something.
