New Light Questions

Hey guys!
So I’ve been running an HLG 100v2, an unknown blurple, and 4 cfls rigged together (86w) in my 4x4 tent. Total wattage was like.. 250 or something. Watts/sqft was like 15.

Just got my new Meijiu 480w LED board today in the mail and set it up! It has a dimmer switch from 23w-480w. I put it at about 280w-300w for now. Should I just go ahead and run it at full power? It gives me 30w/sqft then.

The driver also doesn’t mount to the back. I have it hanging on a bent wire hanger from the ceiling of the tent because I need the heat. Could anyone suggest a better way to hang it or mount it to the board? There’s no damn screw holes..
Should I raise it? It’s 27” from the top of the plants.

I run one of those fixtures in my pheno tent(4x4).
My girls seemed happiest when the panel was about 20" above the canopy.
I would run them at 50% during veg and full power during flower.
I added an extension to the driver output(simple lamp cord) that allows me to leave the driver outside of the tent.
The fixture still; generates quite a bit of heat, so unless you need some heat in the tent, I would remote mount it.
You should see a HUGE increase in yield compared to your od setup.
Best of luck

So far it’s running great. I figured out how to mount the driver on three board finally. I was just a little too baked putting it together.
My tent isn’t getting over like 74f though. Gonna remount the driver properly tomorrow and see if that helps. Any ideas on getting that temp up though?
