Amazon has 4 qb120s for $139... It just so happens that the drivers that i have will work with them... Would 8 of these be too much for a 4x4x8???
8 should work great in a square pattern leaving a hole in the center(think tic tac toe).... thats max of 560w which is a bit high but thats what dimming is for....i would probably dim your drivers down to 300-400w to start and slowly push up to 500w once/if your plants can handle itAmazon has 4 qb120s for $139...

Shouldnt need any with the 120's, although i would put an oscillating fan just above light height pointing down at the topside of the leds if you can .... this will help cool the boards drastically at the cost of heating your tent up a bit.... the faster you run the oscillating fan the hotter your tent will get but the cooler the leds will be sorta deal...What about heatsinks?
So basically im gonna need only the framework???Shouldnt need any with the 120's, although i would put an oscillating fan just above light height pointing down at the topside of the leds if you can .... this will help cool the boards drastically at the cost of heating your tent up a bit.... the faster you run the oscillating fan the hotter your tent will get but the cooler the leds will be sorta deal...
Yeah, i like to build mounting locations for my drivers into the frame, but thats up to you.... the center of the frame should have room for a coupleSo basically im gonna need only the framework???

qb288s can be run without heatsinks only up to 60w, and the qb120 v2s can be run up to 70w... also keep in mind that the qb120 uses a more efficient led than the QB288 V1.... with 6 288's he would be maxed out a 360w which just isnt enough, and he already has drivers for qb120 i believeQB 120's are better in a small space. look at it like this, 4 QB 120's have 192 fewer LEDs than 2 QB 288. it would take 11 QB 120s to equal the output of 4 QB 288. I'd go with 6-8 QB 288. They too can be run without heatsinks up to I believe 70 watts. The QB 120 maxes at 60 - 65 watts. Yes its a bit more cost but not much. And you can get QB 288 V1 right now for $45 each on sale at HLG. Hell you can start with 6 and add 2 more later if budget demands! Six 288s produce a hell of a lot more light than eight 120s. The difference is psread with 6 is more than made up for by the increase in photons.

Yes I do!!! 2 of them!!!qb288s can be run without heatsinks only up to 60w, and the qb120 v2s can be run up to 70w... also keep in mind that the qb120 uses a more efficient led than the QB288 V1.... with 6 288's he would be maxed out a 360w which just isnt enough, and he already has drivers for qb120 i believe
Well @pop22,I'm gonna take your advice cause I love the 288s!!!If I had the money to spare, I'd buy 9 QB 288 v1 and run them at 45- 50 watts per board in a 4x4. High PAR, high efficiency, would make a good SCROG light!
Im trippin,I wasn't even paying attention to the light back there!!! 9 of those in a 4x4??? Can that even be done??? SHOULD IT??? Yeah,I'm looking for the BIG BANG FOR MY BUCKS!!!
You could get 10 F Series strips each with 288 of the same diodes for a heck of a lot less.
That looks like something I would be interested in!!!View attachment 4392461
Add two 480 drivers and this is what it looks like, not that hard to diy
