Vero 29 selection

Are you talking aboput (Logic) growmau5's design. or Chiled's?
Or QB's with Samsungs?

took out 1200W of HPS and 1400W of AC. and put in 760W dimmed down 75% ... hundred less a month.

and growmau5

I owe growmau a lot. Learned from his "how to" vids. I also found out, building them is "addicting" lol I have 6 of the QB 360's I haven't used yet. They will be my next project.

jussayin tho. my qb savings save me 1400 a year, which pays for another 765W light setup. I can double my output year over year now for the same cost. 2600W replaced by 750W. I do have about 400W of other pumps/ fans stuff running but. thats using a little under a third of the power I was before. whoever says this isnt scaleable to commercial levels is a weiner.

10k per 20x20 for qb roughly. maybe more. but if you build yourself you can easily do it. who doesn't pull at least $10k profit per run that big shouldn't be growing that big in the first place.

Hi guys

I've already have six VERO297GEN BXRC-35G10K0-B-7X.

How can I choose the driver?
Will a HLG-320H work?

@Pedro Mello
You have COBs with a 36.6 voltage.
Well, that's what I found after a copy/paste of the part #.
We're going to need more information to get that driver question answered properly.
Let us begin.
What do you have for heatsinks?

Aren't the 'B' versions 51 volts?

My cobs are 90cri, 1800mA; 52V; 93,6W (I found this info on its catalog).
About heatsinks: I live in Brazil, which doesn't have a good passive heatsinks market, so I already bought six Alpine 11 GT coolers.

My initial idea was to use HLG-480H-54A. But now, with the high of dollar I've been thinking in another alternative.

2 x Meanwell xlg240-h-ab should work great aswell with a little less $$$

Thanks, Rocket!

In this case, should I build two circuits with 3 cobs parallely connected?

What about fuses? One per cob? How can I choose it?

And the coolers' circuit is apart? How do I proceed?

Does the XLG-150-H-A would work for 3 cobs which are 90cri, 1800mA; 52V; 93,6W (vero 29 BXRC-35G10K0-B-7X)?

It's the only driver that I found in Brazil and think that might works.

Yes it should work, but at around 50w each cob.

How bad would be that? Do you recommend two cobs per driver (instead of 3)?

The more cobs per driver the better, running soft will increase efficiency.

Do I have to assemble the three cobs by making parallel connections, right? In this case, one fuse per cob would give me the necessary security?
How can I choose the fuses?

Dont know, i usually dont use fuses.
