[JPinkPaw]

I recently purchased and installed a HLG QB288 V2 RSpec DIY light set

To Wall Power AC:

Husky 9 ft. 14/3 Medium Duty Tool Replacement Cord, Black HD#342-576 - The Home Depot

Acquire the HUSKY 9 ft. Black 14/3 Medium-Duty Tool Replacement Cord HD#342-576, UL certified is medium duty with a kink-free cord from The Home Depot

www.homedepot.com

The setup works; as advertised the light is very intense. Am running 12/12 over 6 plants in hydro.

Issue 1: Heat
As the kit nor the driver came with an AC power cord to the wall OR the wires for the DC lights-driver. I sacrificed an extension cord for DC side and because I had the extra length located the driver outside the 4x4 tent; As noted I had pre-emptively purchased a heavy duty "replacement" cord with ground for driver to wall.

I was very surprised at how hot the driver gets. I put it on a ceramic plate rather than leave it on the wood shelf. For context I can put my hand on it for just a few seconds. Probably not hot enough to burst into flames, but still...
>Is this normal?
>Might the driver be cranked too high?

Note the lights can go to 350W, The driver rates at 320W and the wiring I used should be capable at both the DC and AC sides. I have it plugged into a normal 120v/20amp wall plug.

Issue 2: Caveat Emptor

As a heads up this set is sparse and only included the screws to attach the boards to the heat sink. No wires, spacer feet, hangers, or wire.
Its a great product but was left me scrambling to get it operational.
Always good to know what is in the box

Thank you for any input to the heat issue.

Issue 2: Caveat Emptor
Before I purchased the kit I did a good deal of diligence. I reviewed many videos showing how to assemble the device. The kits were showed as having wires, hangers, spacer feet, WAGO connectors; unclear if the AC power cord was included with the Driver.
The kit I purchased showed the 3 panels and heat sink...driver to be purchased separately.

Anyway, The kit I bought was ummm....sparse. Long story short it only included the screws to attach the boards to the heat sink. No wires, spacer feet, hangers, Nothing.
Its a great product but this kit left me scrambling to get it operational.

Hey man, according to your HLG link, you didn't buy a kit. You bought a Slate 2 triple heatsink and three QB 288 V2 R-Spec boards. This is plainly written under specifications on the HLG link you provided.


Here is a link to the 320 watt kit.

320W XL QB® V2 Rspec® LED Kit

Ultra High Efficiency LED Boards for DIY. QB288 has 288pcs Samsung LM301H LED. 320 Watt Lamp Kit suited for main light and supplement lighting. 3 ft. long heatsink for a wider spread.

With regards to the "missing" components, would you mind amending your OP to show that you did not buy the actual kit as you originally thought?

I thought the same thing when I got mine. I was like “this is going to melt itself” hot. If you lower the amplitude just slightly it helps a ton

No, you didn't.

Not quite enough, unfortunately. It seems you didn't fully read the information on the page of the product you ordered.

You got everything the product you bought listed in its contents, you bought the 'wrong' item, and then had to go get the additional parts that are included in the kit you meant to get.

I was very surprised at how hot the driver gets. I put it on a ceramic plate rather than leave it on the wood shelf. For context I can put my hand on it for just a few seconds. Probably not hot enough to burst into flames, but still...

Good idea not leaving it on wood. Depending how hot it is, yes. They get surprisingly hot, especially on max. 50-55* C from what I remember. Do you have an IR thermometer?

I agree with @Barristan Whitebeard, you should correct your original post.

 

[JPinkPaw]

I will amend for clarity. I appreciate the feedback.
The issue however was that items like the spacer feet and the hangers are pretty important and can't possibly be costly. It almost looked like they forgot to throw in the second hardware bag. I 'did' get two bags of screws which was total overkill...perhaps this helps lend some perspective to my OP.
<<<>>.
There appears to be an adjustment screw on top of the driver...if I nudge that down maybe it would help mitigate some of the heat.

Thanks for the responses.

Shouldn’t there be two?

 

[Barristan Whitebeard]

Shouldn’t there be two?

The OP bought an HLG-320H-C1750A , which is a constant current driver with internal current adjustment (no voltage adjustment on HLG CC drivers).
