4x QB120 - HLG-240H-C3100B

I purchased the HLG 120 4 board package directly from their site, they never seem to be available on amazon.

I also purchased the recommended driver, the HLG-240H-C3100 from Arrow, link contained in the above link
This gives me 240 watts of max power out of my 4 boards.
So far I haven't soldered on a potentiometer.
Very simple to wire up, wired all four in series which basically means you're just stringing them all together.

Lovely looking ladies. So you got that LED setup for barely under 200$?...Damn you're making me want to follow suit lol...but I'm horrible at DIY projects, I would likely end up electricuting myself to death lol.

Thanks, I'm swapping my 2x4 veg tent to these lights too. save myself 360 watts


Disclaimer: I am not an electrician, at all

I've never wired for AC, so that required a couple minutes of research, however it was pretty easy to figure out. There's a chart for your country and normal colors for ground neutral and hot, it's hard to mess up.


Basically the LED driver comes with 3 bare wires, so all I had to do was solder the three wires to a thrift store 6 ft extension cord I found for $3
The driver itself tells you how to connect the wires

Then all you need to do is connect the boards together, I chose to do series for simplicity

It would save me tons considering the fact that I'm using a 1000w HPS and it's not far from summer time over here. I appreciate your input!
