16 Cobs per 4x4 for max efficiency I believe is what most are doing
Solid options for pre-fab led that wont break the bank

then that's wayyy worse.
cobs is not a good "warehouse" lighting I guess. you could cover every inch with DE 1100's for a faction of what it would cost to do cobs.
there is spydr, and vyprx, and stuff would be a better option.

Oh, FUCK NO. MH lamps belong on the scrap heap of history. Use CMH lights with square wave ballasts instead, as they're far more efficient and the spectrum emitted is better, too. As a bonus, CMH lamps last a lot longer than MH as well.

Cxa 3070 the same as cxb??? Why is the maximizer at Johnson lights so much more expensive? Furthermore all the other light site had poor interface or market price for what it is?? I understand pricing in the cost of labor but holy shit

Lulz at COB LED being unsuitable for commercial use.
Do you have any data to back up that claim or did you just pull it out of the pot forum wind machine and take it for granted?

you're not gonna cover a room that size with units like that.
look at stuff like this https://www.fluence.science/technology/vypr/
its not much cheaper, but you will have less units.

just price wise, Id love to see a 100x100 light up by 3590's
id make a raise and lowerable celling, or sections.

If led can be used in a 16x16x10 the same way in my house it will be not only worth the over head cost but ridiculous not too...ive seen yield and grow time efficiency when used properly even resin increases..im not here too argue led, cmh,mh. I tryna find the best led system for cost in bulk

12'x10'? You want 15 of these. 20 on the high side.

16' x 16'?
32 of these. 48 on the high side.

Email for the bulk pricing. ~2.2umol/j at the wall for right at $2/watt.
Gravitas are ~1.5-1.6umol/j on the canopy? 1.42x more wattage needed for the same above performance, round up to 1.5x for the better spread of multiple light sources from cobs over HID. $2/watt for led vs $.50/watt for gavita, adjusts to $.75/watt(50% more watts needed). Cost per watt hour adjusted at $.00012 vs $.00018, and another $.00001 to the gavita for added maint costs. The $1.25 more per watt in startup has an ROI at 16,666hours. Right under 4 years with 12/12 at us average of $.12/kWh. The cxb3590 will still be above 90% at this point.

I'm running 144 sq ft lit exclusively by CXB3590.

and how many panels and cobs?

24 modules, each of which consists of four CXB3590 3500K CD BIN 72V chips driven by a Meanwell HLG-185H - C700B. Each module is responsible for lighting 6 sq ft.
All this is on my thread, link in my signature line.

I'm just getting by with what I've got. This one is getting rewired.
These old ballasts work surprisingly well. Almost zero noise & they don't generate much heat. The bulbs I like are $20 but there are cheaper alternatives.
