Quick DIY Build 2x QB132 150W

Finally got around to pulling apart the 4x fixture and converting it to a 2x. The previous setup was four qb132 boards w/a meanwell lrs-350-36. This new build is a two board setup running an hlg-150h-36a. I'm adding this board to the 5x3 flower room to run perpendicular to the 350R on one end. Just the corners in the room were kinda lacking. I think 500w total should fill this space nicely.

New driver vs. old driver. The hlg series driver is definitely nicer. Doesn't need an internal fan like the LRS series which is a nice upgrade. That internal fan was noisy af.

Those boards are bulletproof! 75 watts each. Good shit. I still run 8 of them in a 4x4 for 3 years straight now ?
Your right about the fan on the lrs drivers, But the price is on point for a 350 watter

Heck yeah the price was right on the driver AND the four pack of boards for $99 delivered Amazon prime lol.

I can imagine what they want for the new hlg blackbirds 730 watts. 6 "boards" they are sharp. But black?

They do look nice and I'd kill to have one, but you're right the black is a bit odd to see on a grow light. Guess they didn't want to confuse it w/the Diablo line?

Hey M.R. Dog,
I run all DIY LED lights, but I run strip lights and I don't have any experience this QR boards.
I have a couple of questions, if ya don't mind...
1) Do the QB boards run ok with no other heatsinks used? Is a passive fan needed for cooling them?
It looked like you were just able to use angle as a framework and go. Is that the deal?
2) It looks like you are using a Constant Voltage drive with the boards. Is that the way the boards are rated?
Just match the required voltage for the board with the voltage output of the driver, and make sure your driver is big enough to handle the amp draw?
(With strip lights it's kind of the opposite, you use a constant amperage driver and number your strips to the voltage window of the driver.)

Everyone I know that has used the QB boards has really liked them. Seems like you are pleased with them also.
What color temp of boards did you choose? You don't by chance have a link to the ones you got do you?

Thanks for letting me pester you.
Cheers,
WillieP

Constant current is good in series. Constant current is parallel.
No heatsinks needed for running them full blast.
I'm using a lrs 350-36 and I turn it right up til it blinks then down a touch. Shiuld be running right around 300+.
They dont sell an anymore but I'd be willing to part ways with a setup or 2 ?

These particular boards don’t require a heatsink which makes them very DIY friendly. Unfortunately HLG no longer sells these QB132 boards.

They can be wired for either series or parallel. The driver I chose was recommended from ledgardner.com for running two of the boards. I’m not sure if they make a higher voltage driver @150w to wire these in series.

Mine are 3000K. I ran four of them for about a year in a 4x2 tent and I can’t tell a difference in the results between them and my new 350R. So yes, I think they work great!

@TerpyTyrone @MtRainDog
Thank you both for your replies.
I did a little digging after I dropped my questions, and I came up with these on Amazon...
Amazon product

Those with the recommended driver...

Looks like you would have a ballpark figure of $125.00 in a 240 watt, full spectrum LED, dimmable light.
Seems like a pretty good deal to me.

I don't really 'need' a new light...But it's not like I 'need' more seeds either... :ROFLMAO:

Thanks again,

Nice find. Although it looks like you need a heat sink for those boards. The seller shows them attached to heat sinks in their example wiring diagrams. Makes sense given they're 120w each.

Good catch, I did see that as well.
They sell these on Amazon as well...
Amazon product

That would add about $60.00 to the build.
So, $46.00 for the two QB boards, $58.00 for heat sinks, and around $86.00 for the driver.
That puts it to around $190.00 for a DIY light. True 240 watts, multi spectrum, dimmable...
Is that a deal, or can you just buy a DIY kit for that?
I'm completely a Newb to QB lights, I honestly don't know.

Sorry for high jacking your thread.
I think I would like to try one of those style of lights, and was just curious.
Thanks,
WillieP

That's a great deal for great tech IMHO ?

I used stainless steel cookie sheets for heat sinks on my pair of QB120s (120 watt driver so they are only running at 60 watts each).

Heat sinks are not required but dissipating the heat makes them last forever...and the seed starter feature is a bonus.

The ones i got were 12 x 16 and i put 2 together with 3/4 X 1/8 angle aluminum. Works like a champ.
