In my defense, I purchased the fixture this most recent black friday, prior to finding this wonderful community.
And full disclosure, it came out of the box like 40 days ago lol.

Cool.
The fixtures I built on the idea that I wanted to be “modular”, for lack of a better term. So they’re almost like the equivalent of a “bar” style except they use premade boards - in this case HLG Quantum Boards, with the matching heatsinks from HLG.
The “fixtures” are 32" “long”, by whatever the “width” the heatsink needs to fit into the frame (8.5"), and then one would just use multiple of these “fixtures” to cover whatever area their grow/canopy is. Eg: One QB 288 fixture would easily cover a 2x4 (probably easily a 2.5x4), so if one’s canopy was 4x4 they would use two “fixtures” (hung independently). If the canopy was 4x8, then one could use four fixtures (each one basically covering it’s own 2x4 foot area), etc. Depending on height from canopy the “4 foot” canopy dimension could be probably be stretched out to at least 4.5 foot. Originally when I started assembling these, I used 240w drivers, then I moved mostly to 320w drivers.
I basically used HLG kits like this: LINK, to make fixtures of a similar form factor to HLG fixtures like this: LINK. Two board fixtures. One could use a piece of aluminum/steel angle or similar to attach these fixtures to at a set spacing to make them like one single piece, though.
I really like(d) the diy aspect.
Two of the fixtures with r-spec boards would be similar to this product: LINK (“Flowering Footprint 5’ x 5’ at 28"”, from specifications). You’d have a bit more wattage available too (2x320w drivers).
Two of the fixtures with diablo boards would be similar to this product: LINK (“Flowering Footprint 5’ x 5’ at 30"”). Or two of these: LINK (“Flowering Footprint 3’ x 5’ at 15”).
So, this HLG 350R is a good comparison of what I’m talking about as far as the fixtures I have that’d each use two QB 648 Diablo Boards powered by a 320h-54A driver. Two of which should cover a 5x5 canopy just fine.
Hope that helps.
I couldn’t find pics of my fixtures in the ocean of terabytes on my HDD’s. I know they’re there, I detailed my builds and assembly often. I’ll snap some new pics of stuff asap, hopefully have them up tonight.
I have some QB 288 r-spec boards too. Brand new, voltage tested. Not assembled.
Thanks.
@HeadyBearAdventures too, just in case.

Hey man, no problem at all. It’s all good.
Oh - just saw this. Ok.

Those Diablo boards are really wide spectrum iirc, way more blue and blue adjacent spectrum than, say, spider farmer or the like

Note: I should mention I’m in canada.
Note to self: I should check the estimated cost of shipping a parcel that is at least 34" by 10" by maybe 6", and the weight, before I get ahead of myself, haha. I might already be there.
I’m doing too many things at once today.
Yea, they have more blue than their r-spec boards. They have 648 diodes versus 288 diodes (not including the red diodes. HLG didn’t want to call them “QB 666”, so they didn’t include the reds in the number. Haha!).

Ah okay… yeah the Canadian shipping might kill any discount.
@Nitt if that doesn’t work out, what would it cost me to get the parts and leds you’re talking about, and build one out on my own?
I’m handy, just haven’t messed with electricity much. Relatively simple?

Hmm, I’m not sure off the top what it would cost you. But it’s relatively easy, I think.
You’d need:
-LEDs; Quantum Boards (if going the HLG route). Can be bought with or without heatsinks from them (should come with small hardware to attach to the heatsinks).
-Power Supply(ies); Drivers.
-Wire.
-Wire connectors (Wago Lever Nuts are commonly used, and better than wire nuts.).
-Something for a frame material.
-Hardware for the frame construction, and to attach boards.
Tools, to cut frame material, drive screws, cut and strip wire, etc.
I might be forgetting something, and there’s always more you can add in (like water proof connectors, and potentiometers ie: dimmer - depending on the driver and desired setup).
HLG used to have a page for selecting drivers for certain amounts of boards, for either series or parallel wiring.
LEDgardener did videos on some of this, as did some other places.
EDIT: I’m likely forgetting a couple things. And depending how nice you want things to look, there’s a little big more to it and probably required tools. Eg: a hacksaw isn’t going to make “beautiful” cuts in frame material, like the metal cutting mitre saw I got will. I’ve got small totes full of connectors, cables, spools of wire, solder, etc. around from this “hobby”. Haha.
I don’t wanna derail this “sale/trade” thread though, with diy info and stuff. But if you want you can pm me and I can maybe help out a little. Also, if you wanted to go the “diy” route, I could still sell you a driver or two if you needed. That wouldn’t be as big/long and awkward an item to ship.
There are definitely write-ups and videos on some diy stuff that should still be around.

That’s good to hear! If you do a round let me know how you make out. My only concern was that it was some no name brand but it looks legit.
