I'm looking on Amazon. HLG QB120 v2 vs QB132 v2. What exactly is the difference? And how big a space will these 4 panels light?
And is there any benefit of going with a Spider Farmer SF XXXX instead of the HLG set? Other than pre built. And what size SF XXXX is equivalent to these HLG kits?
Educate me please.

Posted similar question days ago. Daze ago.
So the SF 2000 is twice the light amount that the HLG kits are power wise. So the SF is cheaper and pre built. So what about the differences between the 2 HLG boards and the SF boards?
Thanks everybody. There is a lot to digest all at once when you start into it.

Qbs have 120/132 less on each board. SFs have somewhere probably closer to 180-250. Really not sure. Qb 132's don't require any heatsinks up to 60W so a 240w light using 4 boards gives you a very nice spread. 8 can do a 4X4 like a beast.

@Hust17 the MW 240h 1400 has a voltage range of 89 - 179v
QB 120 runs at 22v at 1400mA
22v x 4 QBs = 88v....... min volts on driver 89 so ~ possibly
Definitely not 3 boards.

8 QB 120S would be a good fit to fill that driver up.

Ya you'd wanna utilize the ability they have to run at 75w passively without a heatsink though and run them at 2100MA, and get the 65-75watts of each board using the 132's.
Or if you're set on 120's hit the 2800MA they can handle for the 70watts each board

Thank you! Do you think that would be a penetration issue running boards at that low power?

Ive a qb 288 running around 50 watts and it gives decent light.
it's still 240 watts of photons. Youd need to have them close to the canopy.
1 x board at 30 watts per sq ft. Run them soft, run them closer to canopy, less light losses to the walls, the lights' spread out, or put them very close and raise the light.
Found a Migro test on one... in a 4 x 4! Lol 18" distance


Do you have a spare 240h 1400A driver lying around and you're trying to think of the best way of using it?

Well it’s hooked up to COBs and eventually I’d like to move into boards. Likely not for another year though I was just curious. And thank you guys for the answers I really appreciate it!!

Dang he said he’d do it again in a 2x2 maybe it’s in a different video. Thanks though that’s great!! It would likely be for veg too
