So I am thinking of building a new light for my 2x4. Currently im running two qb96's on an HLG 320h 54a driver. Its not a bad light at all, but I'm just itching for something better. My question is could I use my current driver to power two qb648's? Or should I scratch this idea and go with something else. It seems the quantum bars are gaining popularity, maybe I I should go with those instead? Any help or advice is greatly appreciated

I have a single Diablo board in a 3x3, I'll have to see what driver it is using, not sure if that will help you at all though. I know it's 200 watts and turned down to 138 for a veg light.

Ya you can use your driver. But you would need a minimum of two boards or you can run your driver dimmed down to no more than 5amps. And of course the boards need to be heatsinked appropriately.

You can get the 648's here hlg doesnt sell them diy style anymore.
The 2 board assembly would do well in your tent https://cobkits.com/product/double-diablo-assembly/
That's where I was planning on getting them. Do you think this would be a worthwhile upgrade?

I have two at 320w and they work good. Definitely an upgrade from a qb 96
Mine is in a 3x3
Cool, thank you!

I have mine in series with a 2.8a cc driver.
You should have no problems with the driver you have and the boards wired parallel.
I do run mine dimmed in veg though. They are very bright at 320w.
I've run pairs of 648 diablos on that same driver. Works well. Definitely an upgrade. The 648 Diablos need a slightly higher voltage than the rest of their 54V qbs (which is why this driver is able to run them). If you get the 648s be mindful of the polarity, they're sensitive to correct polarity. You'll probably see a note saying as much on cobkits site.
