I use x4 @ 636w over a 4x4 & that's plenty.
The Covers over the diodes come factory stocked on prebuilt units & are important to me. Although a defective one may slide by & fade.
I would not run them harder then 160w each. That keeps you around 2.0+ umol/j. Anything higher then that & your getting into lower efficiency then 2020 has to offer.
Personally, i like the 96's over the 288's.
Added IR strips would be a nice touch.
If your leds lack ir & your room is cold in the winter then an hps bulb wouldn't hurt.
I'm about 75% completed on putting together my 4x QB96 setup, and have been trying to decide what to do as far as IR. I've thought about adding 150w hps to the 4x 96's, OR adding 4 of the small HLG IR strips. My space is somewhat cold in winter, but pretty perfect in the summer. Maybe I need both options for different seasons.
