we ended up ordering 56 vero 29's and 14 meanwell HLG-240-H-42-C.
Vero29 with Osram Drivers

use 4000k vero29 NOT 3500k..and those drivers look very nice, especially if you get a good price, they are OSRAM??? says it's made in Taiwan, that's good!
but you went with meanwell.. cheaper?

They suppliers that bragged with their very good pricing is now out of stock. So we decided to go for the mean-well.
Why do you say i should go 4000k?

So i should rather take the one with a lower Vout?
Also, because there is like 5 people involved in this bulk order the oakes cant make up their minds, and on top of that the local driver supplier just phoned and he can find the driver we originaly wanted to use.
here is a link to the one that we will probably end up buying.

that would also make the thread tittle correct.

Yeah those will work for 1 COB each. Nice that they have three selectable output currents. It runs on 220 AC so a little less flexible than 110 but maybe you have a 220 system in mind. They do look very compact, width-wise.

its better for veg, works for flower,and i'm using the 3500k now, it's OK for veg kinda of slow growth to be honest, something is missing from the 3500k, the blue... sucks about the other drivers, those looked promising, and one per light is better, you get better adjustability, each LED is not exactly the same. 7% Tolerance for those leds... those leds also work great at 79w ea.. seems like you grow is not worried about power consumption like most of us.
also get the pigtails connectors to simplify your install for the vero. Molex,-LLC 0688014229
18" long will work perfectly, saves times not money though.

BobCajun- The HLG240-42 will work fine and yes you have to run them in parallel with this driver. This driver is a constant current driver until you hit 42v, then it locks it down at 42v and runs as a constant voltage driver. I would run no less than 4 Veros on that driver incase of a loose wire or a burnt out COB, the rest of the COBs will still be running at a safe wattage.

I see, okay thanks. Apparently series is a little safer than parallel, which is prone to thermal runaway. Anyway, he got the original ones so it doesn't matter now, at least not for him.

Yeah i just made payment! 17 cobs and 17 drivers are mine to play with. Now i must get the coolers and start drawing so i can get everything lazercut in time.

I have a few questions. I come from a vert growing style with dwc.
I am planing to do a scrog. How many plants under the screen?
What is the spacing for the cobs with my given setup?
Big rectangular room so rectangular scrog dimensions would be cool.
@SupraSPL would you pretty please calculate my effietcy?

1 plant per 4 sq ft is a good starting point. Space your cobs evenly. You haven't given room dimensions so it's hard to say much more. Might be crazy amounts of light or not nearly enough.
I'm not Supra, but he made spreadsheets. Your cobs will be running at 43% efficiency at 1400ma, making about 22 par watts. But that driver is only 86% efficient or so, which drops overall efficiency down to about 35%, about the same as a good HPS setup.

fucking customs just charged me $270 for import taxes!! fml!
At least the cobs are here.
I bought 20 x alpine m1 passive cpu coolers
23 cobs vero 29 4000k
and 20 osram drivers

When buying Vero 29s it may be worth considering paying a few bucks more for the "Decor" version. It has the spike at 640 nm instead of in the yellow zone like all the standard white COBs. You'll be running them for years so might as well get the best spectrum. It's less than $5 extra and you get at least 50% more usable red, by visual estimate comparing the spectrums. The spike is actually pretty much perfect for plant growth. It also has more far red. If you don't want the stretching effect of far red you can counter it with 5 minutes of low intensity red light after the main light turns off. It's called EOD red if you want to look it up. Sort of the opposite of EOD far red.

if u go with the original drivers why not the 1600mA ones?
I dunno the exact numbers but the veros use less volts than cree from memory so you would be running them at less than 50w each at 1400mA- hence a lot of wasted space on those drivers
also you should do a search and find this info(its on here somewhere
