New grower

[Dylanmark]

Anything HLG is pretty much held as the standard for LED panels right now. Cant go wrong with any of their stuff.
I saw you were on aliexpress. If you want to order from china, get on alibaba and go Shenzhen Meijiu Lighting or Shenzhen Kingbrite Electronics


Lot of people overlook them because theyre 561s and arent the newest best thing.
I still love my 561s. It would have cost me nearly an extra 1k to do what I wanted in 301s at the time.

Think this is what I will go with

I think those 120 qbs dont need a heatsink.

Correct. I run two 4xQB120 (v1) fixtures in 3000k, at 80-250w each (a little over 60w per board) - no heatsinks and they've been doing right by me for a couple of years now. I highly recommend them for full-cycle growing.

Flower tent has about 300 watts 3500k, 50 watts 5250k, 110 watts 4500k and 50 watts of Cree 620 diodes. These are running active cooling (purchased fixtures discreet and COBs.)

Then this driver is the wrong one, op u need 24A, or optimally 24AB

Good catch, I didn't even notice what driver he had linked. I actually use an HLG-240H-C2100A - with the boards wired in series - for each of my fixtures. Going parallel certainly has its upsides though.
