Congrats! The way you have them wired is fine. If you are running them full power on the A version, you are about 94% of max recommended power. I would suggest putting some air to them. At least a 6" clip fan blowing across both. Thanks a lot for all the support!!! Perfect, I had one here just did ...

Hello to all, Just concluded my build of 2x HLG QB324 , with slate 2 heat sink, 90 degree custom optics, mounted on a simple aluminium frame I have built. I have wired in parallel with the HLG-320H-54A driver, using a 3 slots wago directly from the driver, insted os using the boards conector to pass...

The 324 runs about 1.5v higher than the 288. At similar current. This results in a small increase in overall watts. However given that do offer a slight increase off wattage at similar efficiency and they off ER the 3500k spectrum is what sold me on the board. That and the price point. $79 with hea...

There’s nothing special about the QB324. That’s why I suggest learning the fundamentals. You’ll then be able to answer a lot of the questions you have and actually understand the concepts. We have all been in your shoes. Problem is, there’s no perfect option for any build. There’s millions of parts...

These boards run about 140w at 2800mA. On the hlg-320h-54 driver you can get a few more mA of current vs the 320h-c2800. The base current of the -54 is 5.95, that is split between the boards resulting in 2.975 amps per board roughly. That brings total wattage closer to 150w per board. Thanks a lot!...

If you are here because HLG doesn't respond to emails, I feel you pain. A1- parrallel wiring is connecting the positive driver lead to the positive board lead of every board. Then connecting the negative lead to the negative terminal of every board. Series is connecting the driver + to first board ...

Hello! Hope is all good! I’m new to the forum, have read, and see a lot of content from the LEDGARDNER which inspired me to make my first Quantum board build. I’m setting up a 3.3x.3.3(100cm x 100cm x 200cm), that’s around 10,89 sqf. Initially i was thinking in the 4x QB 120, then i have got the sug...
