Why? Run them at 1750 on 2 240h-c1750b's.I
am in the process of building two of these in an H-shape configuration with 8 cxb3590, 36v on 2 c1400's.

for someone that burns out their cobs I wouldn't be giving adviceWhy? Run them at 1750 on 2 240h-c1750b's.
I am designing the fixtures to operate at a 56% efficiency. More photons is better growth, not more watts. I also remotely mount the LED Driver, as well to further reduce heat gain. I will be setting up a two CoB CXA3590 36v, 5000k, 145w, CD bin with a 240H-C2100, 2.1 Amps vs 1.4 Amps to see if I can drive the CoB's a little harder and still get good photon's as well. But that is another issue. I have two CXA3590's 72v, 135w, 5000k CD bin with a C1400, 1.4 Amps and I expect two hundred watts and some nice growth potential with another 56% efficiency.Why?

I run the same 4 CXB3590 @50W apiece as many others here do, to get the same 56% efficiency. My drivers don't get appreciably warm. I'm running 24 modules like this vertically in front of 144sq ft, to maximize production per square foot.I am designing the fixtures to operate at a 56% efficiency.

How much space are you trying to cover?I am designing the fixtures to operate at a 56% efficiency. More photons is better growth, not more watts.

I am learning fast. thanksI run the same 4 CXB3590 @50W apiece as many others here do, to get the same 56% efficiency. My drivers don't get appreciably warm. I'm running 24 modules like this vertically in front of 144sq ft, to maximize production per square foot.
That's a badass setup for off the grid growing, brother.I have also modified my veg light to 4-CXA3590, 72v, 135w, 5000K and C700B for the same effect and an efficiency of 64% from a 2-CXA3590, 72v, 135w, 5000K and C1400.. should be great for vegging. I increased my heat sink to double and mount them side by side for a 12x12 footprint in a 2x2 tent. should be excellent coverage. also have reflectors lidel angelinna's to increase lumens with the same wattage by 15%. Adding reflector's to the 8-CXB3590's as well. in a 2x3 tent
On what?late april early may on that
The answer is yes, they're working their way down the spectrum. No word on availability as yet.i musta wrong threaded
somebody was asking about availability of hlg-320c drivers
stoked for the DB 3500s
you should ask them if 3000 is getting a bump from CB to CD
there it was. fast moving thread, glad i wasnt going crazyHavent been able to find anywhere to buy it yet.... Someone told me it was coming out this spring on some forum so ive been keeping an eye out for it and finally pulled the spec sheet the other day
3x3How much space are you trying to cover?
4000k DB bins have been out for some time nowOn what?
STRAIGHT FROM CREE TODAY:
DB BIN 4000K CXB3590 are available now
DB BIN 3500K CXB3590 have no part number assigned as yet. Once they do, a prepaid order will be filled in about 5 weeks or less.
I'M stoked! I wanna use them at 75W each, I bet the efficiency would basically match the CD bin at 50W.yes i got some from cutter a month ago.
DB 3500k is exciting
The bin jump happens when AVERAGE chip specifications increase by 1000 lumens. Therefore the bin jump is over 8%, from 12k to 13k lumens/watt. This is how it was explained to me, at least.more like @ 60W the DB would be as efficient on lumens/w as 50W CD. same DB run at 50W would be ~5% more efficient than CD
im assuming current CDs are toward the top half of their bin spec and the new DBs are toward the bottom half of their bin spec for now
even a "full" bin jump would be about 7-8% going from say 12500 to 13500 lumens
