Been creeping the threads for some time now and am finally looking into these three lovely HLG kits/builds and was looking for opinions for a 4x4 tent after I move here shortly in the next month or so.
They all seem rather similar to me, obviously using the same V2 boards from what I can tell. Not super enlightened on the whole process of leds but have been reading up a lot of par, ppfd, and umol/j. Not so much on applying driver strengths, mA, etc applied to to various boards which is why I'm leaning these 3 instead of easily picking one or building from scratch I suppose.
I decided to qb due to simplicity for now although one day in the short future maybe I'll get a little more hands on with strips.


Anyhow, the first 2 prebuilts, the difference is only the driver essentially? One up to 480w, one to 600w with Bluetooth?

The last xl kit (x2) would be 6 boards total instead of 4, at 640w total. Figured could be dimmed when applicable but with more of a spread and more effeciency?
I also like how these 2 rows of 3 boards could be more versatile and if I wanted to use them elsewhere in a smaller tent or something later, i could split them up if need be (without breaking them down) with them not being built 4 into one frame like the first 2.

Its a pretty big chunk of change for me so I figured I'd ask for opinions, hell, maybe I'll learn a lil bit while I'm asking. I am trying to learn as much as I can about it but I'm gonna order the lights soon.(or else ill spend the money)
Sooner than I can probably wrap my head around it all which is why I'm here.

Leaning toward the 3rd option right now being a little more versatile. However it's almost 640w across 6 boards, as opposed to 600w across 4 in the hlg600 and correct me if I'm wrong but it'd probably be better to have something with more power, running dimmed, to be more efficient, on top of the 2 extra boards increasing spread. Idk, maybe there's something I don't know, am misinformed on, or am overlooking.

I thank you all in advance and any constructive input is much much appreciated.

I would opt for the two 320s. More boards means more coverage, and at a wattage equivalent to one of your other options, more efficiency as well. You would also gain the advantage of more adjustability where height and placement are concerned.

Hey man, cool thread. I was recently thinking of upping my setup to a 4x4 and because I wanted to run a split harvest, I wanted two individual lamps myself, so for me versatility prevailed and in your scenario, I'd say the same applies because, and to vaguely answer your one general question about how they'd all compare, you're correct in that they're all functionally the same. Regarding dimming them for efficiency, yeah on the constant current driver in that setup, dialing it down reduces the current to the boards, running the diodes more efficiently, and allowing you to keep them closer to the plants. You'll lose uniformity as you get closer though, so you shouldn't go crazy.
