Hello everyone, I just noticed that HLG has the QB 96 Elite V2 Engines back in stock today. I guess they finally received some more thermal pads.

I just bought four complete with the SSTX heatsink and thermal pad.
What driver/drivers to push them to the limit ?

I think with the splayed heatsinks they're capable of r ecco mended Max 224watts at 4amps with an absolute Max of 350watts at 6amps. So if you have 4, you need to run them at whatever your growing space will allow. What's your area dimensions?

The space is as large as I want it to be. I’m going to use a dimmable driver. I’m thinking HLG-600-54a in series for 4

You'll want to wire those 4 QB 96 in parallel.

I’d rather wire in series. What driver do you recommend?

If you want to use a 600 watt driver, Inventronics is a common choice.

wiring 4 in series will put you in the above 200v DC range, which to me begins to feel dangerous.

Ok then let’s use two drivers. What do you recommend?

If you want to stick with passive cooling, 2 QB 96 per HLG-320H-C2800 (A,B, or AB) wired in series.

Ok, I promise one more question.
Let’s say I wanted to use active cooling. What would you recommend then for 2 96’s in series ?
My plans are to dim the fixture if not using fans. Options are my goal

Something like the HLG-480H-54 (or theoretically an HLG-600H-54). You'll need to wire in parallel. The Mean Well HLG constant current drivers don't output enough current to drive the QB 96's that hard.
Or you could wire each QB 96 to an XLG-240-H-A (or AB) if you wanted to.

You won't be able to get a lot of power out of them if you run them in series. Highest constant current(series) driver is like 2800-3200mA. Just use a 54V Constant Voltage driver for parallel.
But realistically, what's an estimate of your space you're gonna use and just as important, how much ceiling height you gonna have?

Directly from the QB96 page on HLGs website...

You said you wanted to really get some power to them and in this case, these qb96s are one of the only boards that can realistically be driven fairly hard. So if you have enough vertical space to hang them high enough, at least 30" above your canopy, you could run each one at 200+ watts. But if you don't have that option, driving them hard isn't going to work for you.
So just give us an estimate on your sq footage and vertical space and we can suggest some driver options for ya.

The size space is unlimited.

From what I’ve seen the recommendations on the website are not always the only or best options.

Then just run 2 per HLG-480H-54A for 240w a piece .

I decided to go with 2 HLG-
I can always dim them down when not needed or I’m not running fans.
I agree, I’m about to order them. Thanks !
