Qb v2 288 power source

Ok trying to nail down my setup and not sure if it'll all work out properly so looking here for advice.

I want to run 6* qb 288 v2's at 3000k for a veg/flowerb light

My question is what is the best way to power it.

Can one 600hlg-54b power all 6? To my understanding it can if wired in parallel.

Or am I better off running two 320hlg-54b in result getting sightly more wattage?

Or should I run two 320hlg-c1750 or c2100s

I want to be able to dim these down so a potentiometer will be added for sure to any setup.

And reason why I just don't get a hlg550 is because with the v2 288s and slate 1 hs sale you can get more coverage, aka 6 vs 4 for the equivalent pricing if I build a rack myself.

Or do I totally abandon 6 and still build my own rack with 4 QBs and the hlg-600 and call it a day?

With the new qb 288 v2. You can actually run six boards on two hlg-320h-48 at about 109w per board. That would run them at about 2230mA a piece. The 320h-54 might not run them as it's a 49-58v driver. On the website the boards are rated 45.72-49.86v.

Running 6 boards on an hlg-600h-48 would run them about 2083mA a piece for about 100w per board.

Running 4 boards on an hlg-600h-54b would max the boards out at 2.8a for about 140w per board. I would recommend getting a digital display, or multimeter because some b version drivers output more than the rated amps.

If 6 boards is the same price, I'd go with two hlg-320h-48b as you would get slightly more power per board, and about 650w max for about $20 cheaper. The hlg-600h-48 would give you about 600w max for $20 more, and the Hlg-600h-54b would run 4 boards at 560w max for $20 cheaper, and run quite hotter.

Ok that makes sense. Thanks!

= ) glad to help.

Any other insight?

Also can I wire both diming circuits from two power supplies to one dimmer... Instead of a 10kohm up to 20kohm?

If you want to run 2 drivers on 1 meanwell hlg driver. You need a 50k ohm linear taper potentiometer instead of a 100k ohm linear taper potentiometer.

How about three hlg-240h-c2100a. That way can run 2,4, or all 6 as needed and price wise is good option.

If you go 1 driver per 2 boards, I would go with the hlg-240h-48a or b. With the B you could get 2.5a per board, and slightly more with the a model. The more you max out a driver the more effecient it is. So if you need all that power, go for it.

If you don't need all that power step down a driver if need be and try to max it out. That is if a little efficiency means a lot on your electricity bill.

3* 240 would be a bit much I think. That's a little over 700watts... This is going in a 4*4. Most already dial back the be 550 a bit. I was just trying to get similar power with better coverage.

Hence going with 6 boards vs the 4.

Then I compared the 320xl as being good for a 2*4 then ideally I'd need tot setups for a 4*4.

I think I'm going to stay with 3 boards on a 320-48b.

I want to wire the dimmer lines from both drivers to one potentiometer so they'll all be at similar drive levels, not have one brighter side per se.

I'd go up to the three 240 drivers but I plan on adding in some far red after a first grow is successful so I find it a bit overkill considering I'm already going beyond a hlg550 setup and that Vegs a 5*5 and flowers a 4*4 according to hlgs website. Also with the 3 drivers id be more limited on how low I can dim.

I've never grown before so it's all new to me but trying to make sense on where it's wise to spend now vs over doing it.

If I can put in a little of my diy skills and get more bang for my buck than that's what I'll do.
