Running 2 cobs per driver will be fine, but you won't be pushing the driver as hard as you could. You'll only get 8 cobs working like that,
4 cobs with 2 x 2 in parallel is possible, but probably not too bright. I wouldn't wire like that unless I had an individual fuse for at least each pair of cobs. Efficiency will be high though !
Don't mix 36V and 70V cobs, I suppose it's possible but you'd have to work out how the current would be shared between the cobs, and then how bright they would each be. Headache. Much easier to use all the same cobs.
To get all 16 cobs working you'll need to buy another 4 drivers, or return the drivers you have and get different ones. Not sure which driver you need but I'll go have a look.
EDIT*
HLG-480H-C2100B should work I think, you'd need 4 of them I've never used the Vero's so I'd wait for someone who has to confirm it'll work ;)
Thank you, this is what im looking for, the driver chunky posted is ideal because the voltage almost matches perfect but at 2100ma i believe these veros will run too hot.Okay, you have 32 sq. ft x 50 watt/ft=1600 watt.
And the 16 COBs need 100 watts each to reach that.
72Vdc COB x 1.4 Amp= 100.8 Watt...you need a 1.4 amp constant current driver .
You can run a 4 x 72Vdc COBs = 288Vdc at 1.4 Amps on this Mean Well driver.
You need 4 of them. Build 4 separate bars, if you want any control over them.
Or just mount the whole rack to the top and leave it there.
HLG-480H-C1400B
Output Voltage (DC) :
171-343V ( 4 x 72Vdc Cobs = 288V)
Max Output Current :
1400mA
Input Voltage (AC) :
90-305VAC
Dimming Signal :
0-10V Analog, 10V PWM, Resistance
Or get the "A" non-dimming version for $10 lesss

Hey, what about running 6 of the veros on that driver? (68v) because it says it has an open circuit limited of 420v. i would get 80watts per cob? ThanksOkay, you have 32 sq. ft x 50 watt/ft=1600 watt.

Ok i did want ti use my drivers in parrallel series of 2 strings, to get a 700ma current. But, the drivers say 089-179v so i believe these 70v chios would blow up if i did that?
The HLG-480H-C1400B (171-343V ) is 343 maxHey, what about running 6 of the veros on that driver? (68v) because it says it has an open circuit limited of 420v. i would get 80watts per cob? Thanks
when in series, the voltage is divided across the cobs. Your only option is to run 2 cobs in series (140V)
1 cob would be 70V, so below the 89V minimum. It might work but the driver would not be able to operate in constant current mode. 3 cobs in series would be 210V so outside the maximum voltage the driver can supply.
When in parallel the current is divided. 1 cob would get full current (1400mA), 2 cobs would share the current, so 700mA each.
To run them like that you would wire 2 cobs in series 8 times. Then each driver would run 2 of those strings wired in parallel. It would get you up and running, but I still don't think it would be bright enough.

Output Voltage-Channel 1: 171 V to 343 Vok thanks guys! yea when looking at the data sheet for that driver it has a max of 420v...
You would be better off to push plants down from a veg box to 800 watt end of tent, to 1350 watt finish. The light mover sounds klunky if you don't have overhead space, like a tent.Also if i need 50w per sq ft in a 4 by 8. would providing 100w per sq ft on a light mover be the same interms of growth and yield? Thanks, that way i can run two tents instead of one =)
