Anyone still using HLG QB96v2 Elites

That’s awesome! What size space are you running them in? I just need to source and plug and 18 gauge wire and I’m g2g.

I have two 3'x3.5' trays. One tray currently has two 240w 3500k Kingbright QB's and the other tray has a 600w HPS.

Can't decide if I'll replace one of the 240w QB's with the 2 96's and keep the 600w HPS for the other tray. Or get rid of the HPS and go all LED with the 96's in between the two 240w QB's.

What wires do you all use to wire on the DC side, from the driver to the board? I’m using an HLG 186h-54A. I’ve read various things and am up in the air about what to get. I was going to originally use 18/3 thermostat wire rates for 150v. I was going to use The third wire as a ground and attach it to the heat sink and run it back to the driver. I have read that some people recommend using 18 gauge 300v rated wire instead. Any thoughts? I have placed an email to HLG To hear it from the source so to speak but haven’t heard anything back yet and wanted to ask.

Thanks for that link! I’ll go ahead and grab a roll of that. Is there any particular reason I don’t need a ground running from the fixture to the driver? Again I’ve read various things just want to make sure.

The board only has a positive and negative molex connector and the heatsink it is connected to is anodized aluminum which is non-conductive. The driver output side (DC) is also just a positive & negative wire. If you build a frame out of conductive material and mount the driver to it then it will act as a ground.

The driver input side is AC (altern

The driver input side is AC (alternating current) and is grounded.

Hopefully somebody can chime in on spacing.

I built a frame last night for two QB 96 with a 320h driver and mounted them 18” apart from center to center. I left the frame with some extra length in case I need to space them further. 18-24” seems to be the most common spacing, but is that center to center?

I will say, these suckers are bright!

Each QB96 will cover a 2'x2' space plus some overlap, so unless you are planning on dimming them down lower than 120watts each, I'd put them 24" apart (center to center). Personally I don't have mine on a frame, just wire hangers. I prefer that because I can move and raise/lower each one individually to find the sweet spot of each grow.

Good to know, I’ll spread them a bit further. I’ll be driving them around 160w/ea. Going to put them between my 240w QB 288’s.

I was going to just hang them individually as I do have hangers for them but didn’t want to deal with the wires when trying to raise/lower them separately since they’re both running from one driver.
