Straight swap from COB to QB

So it looks like the elites are out. They recommend 320-2800n rather than 320-2100 on the elites. The 240-2100 would be ok though?

Honestly, your beat bet might be the cobs mixed with some strips/boards? Get some red in there and use white strips/boards to supplement around the "hot spots" created with cobs?

What are white strips?

Why dont you keep your cobs and add some strips between them to improve coverage? I am not sure how old your cobs are and although cobs are actually pretty cheap the set up and heatsinks and work you had to do to put it all together adds up. If you let people know the drivers you are using it maybe possible to add strips in and use the drivers you are using now, this will up the efficiency of the cobs and cost fuck all while giving you better coverage.

I believe thats what we came to about a week ago. Admittedly, i don't know much about strips and their power reqs, but iirc hes running an hlg 320 2100? Again, i don't know a heck of a lot regarding COBs, their efficiency ranges, etc, and as far as i understood, i thought mixing even the same qb boards, but from different batches, was not recommended on the same circuit. Then again, i have seen numerous people making custom fixtures here, and other sites, that use various strips of varying spectrum (mainly whites w/ red/far reds) to achieve something similar to what hlg has going on with the qb96. Maybe it "isnt recommended," but is doable, and fairly safe? Maybe this degrades life expectancy or efficiency of the end product (in this case fixture, not the plant!)?

In any case, I added what i could. If the discussion is going to continue, someone would have to jump in and pick up the slack for me. My suggestion would be a smaller driver specifically for the strips. Then you have the cob driver dedicated to them, and the supplemental whatever has a driver committed as well. This allows far more flexibility down the line (either replacing drivers to use drivers with something else, arrangement flexibility with more or less seperate "fixtures," or two parts to be used with x y or z addition in the future to cover more area). This is what i was trying to keep in mind when they released the 96s. I saw the spectrum and knew id be jumping on em, added one to the 288s last run and im sold. Plan on picking up at least 3 more here soon, and putting up a few walls so i can lose the tent, or relegate it to permanent vegging...

Nothing special about that new HLG thing. You could have just got some 660nm strips to run with your old quantum boards. Efficiency will be higher that way and spread will be better.

Better penetration on the 96. Thinking of mixing 4 of em with the 288s to run a 4x8. The 288s solo didnt do it for me. So i went for more light and some red to boot. I dont have a ton of time to be putting together strips, build a frame, etc. So the hlg board+hangable heat sink were a simple "diy"-if you can call running a few wires diy...
