for the cxa's I will be using 2 185-1400 to power the 6.........3 per driveryeah it will still be 4 cxbs. 3590 or 3070
4 cxas wont light up at 143V per datasheet, but it might work
It doesnt work like that. forget about watts for a moment. volts are your concern if you want the chips to light upHi! im setting a 16 cxb3070 3000k or 3500k in a 4x4 tent they would be running at 0,7a equals 403,2w.
One question about the driver HLG-185H-C700A ,could run 8 led runing at 0,7a? that would be:
Each led 36v * 0,7 = 25,2w *8= 201,6w
Total voltage is 36 * 8= 288v
HLG-185H-C700A 200.2W 700mA143-286V CC
So, by real maths, but not real cause not counting the loosing watts, its seem that i would top both W and V.

If the answer to the question is not, what would be the apropiate driver?
Maybe 4 HLG-185H-C1400B?
Thanks!
I run my cobs at 500ma and I get great rsults so 700 will be great as well.Hi!! thanks , looking at the characterization tool i see the cxb3070 at 0,7a the voltage is 33,72 so 33,72*8=269,76V and the driver HLG-185H-C700A 200.2W 700mA143-286V CC is up to 286V, so now yes i can run 8 cobs cxb 3070 at 0,7a.
So now with that been told, 16 cob cxb3070 running at 0,7a with 2 drivers is the setup.
But before ordering, is a great setup? am i having any mistake?Could be a better setup for 4x4, i rather the efficiency more than watts thats why im running at 0,7.I know that 3590 are better but they are more expensive.Maybe for the second setup
But still with open mind to any change that any of you, masters, can give me.
Thanks again,and thanks again to CobKits.
This isn't incredible. Your setup might match the output of the one type over the other better, or maybe it's how they're wired. It happens, there are a lot of variables.I run my cobs at 500ma and I get great rsults so 700 will be great as well.
I have CXA3070, CXB3070, and CXB3590s.
Honestly I think maybe the 3590s yield less for me.
I know this makes no sense, but 3 grows in a row the lower prices Cree cobs are yielding more
I think that 2100 will output around 75 watts each to the cobsHlg 320-2100 will drive 4 cxb3590's at how many watts? Also is it a good idea to add this driver if my other 4 cob bars are running on 1400 meanwells? 4x4 tent. I have two bars in the tent with plans to build a third for a total of 12 cobs in the 4x4 if that helps.
yes even if they were 3070 that driver should fire all 3 cobs.I got a problem I'm trying to get 3 cxa 3590 to fire up on and HLG 185-1400 and no dice on two will light up when I try and wire the 3rd no dice. What give I'm pretty sure they are 3590 maybe they are 3070's but still 3 should light up right?
gen7 didnt exist when these threads were made. theres at least a half a dozen chips out that are both more efficient and cheaper than cxb3590 at this pointwere does the data come from on the vero's? based on everything I could extrapolate from the datasheets the Gen 7 vero 29 seems to be on par with the cxb 3590 atleast when it comes to running on low current and temperature. It has substantially better performance then the gen 6. a lot of the information ive found comparing the vero to the cxb they used the Gen 6 not the Gen 7. can anyone confirm which generation of vero these spreadsheets are using ?
