Actually I plan on building something similar to that but I will use 12 qb 120 and 4 qb 132.I have 12 qb 120 tuned with deep red and 8 qb 132. I will have 4 qb 132 left to do a grow in a small tent and try new strains. I will also add Uva and far red for quick sleep times.

Cool! I'm sure I'll expand on the lights as I go. Seems like a good starting point

Im +1 for qb96: 9 of them with sep drrivers for the corners. This waay you can get perfect even spread and you already get the red sup included. What would the red sup cost at a later date, especially with a qb132 build which would most likely mean monos for proper spread?
The key to the qb96 is the futureability: youll be running them at around 80w each but they could be taken way way higher if you ever changed the space. Efficiency will be fine at 80w.
Qb120/132 are nice but you kinda build them for one space only aand if in a tent the frame can be a real hassle to hang/raise /lower.
9x qb96 comes in around 560$.

@Rocket Soul is right about 9 qb96 I kept thinking and planning if I ever did a 5x5 that would probably give the best layout, 3 hlg-320h-54a would give you an amazing amount of light.

Id probably go for a different driver configuration: ideally you would have all corner qbs on a (or 2) separate drivers: corners allways have a little bit weaker coverage due to cross lighting in the rest of the grow space so it makes sense to have separate control and maybe a bit more power than the other qbs.

It can be difficult to hang the frame the fist time. But lowering or raising the light is super easy.

Maybe it is better because in the future you could use the 9 qb 96 for a bigger tent but 9 qb 96 elite will not give the same spread as 16 qb132. When running high ppfd even spread is key because otherwise you end up with some bad hot spots that go above the maximum that can be useful for plants.

To match the 660nm content of qb96 elite you would need to add like 5% 660nm deep red. For 750 watts that would be like 37.5 watts. Rapidled sells solderless red diodes that make it very easy to build supplemental strips. You could make 3 rows of 5 660nm cree xpg3 diodes and have more deep red than the qb 96 elite. Those diodes run at 4umoles/joule so they would bring the efficiency of the qb 132 to a similar efficiency that the 650R.

I’ve found that my yields have no changed in my 2x4 tent, 320 watts of 4x qb132 and 2x qb96 have yeilded almost the exact same.

At what wattage do you run the qb96 ?
X6xsilverx6X

320 as well, both same wattage.
I had switched the qb132 for the qb96 a while ago, and use the qb132 for veg area.

The only explanation I can find is that you are reaching the light saturation point. Do you use co2 ?
320 watts of qb132 in a 4x2 tent gives an average ppfd of 1223, 320 watts of qb 96 elite gives 1042 ppfd.

And if both yield the same I would still buy the qb 132 because the are cheaper !!!

There is evidence that at ambient co2 more light than 1000ppfd is not useful anymore.
