    Moving up from regular LED light bulbs(will still use them to supplement if needed on the corners). Im from a less than legal state so I dont plan to show picks of plants but i just wanted to let you guys know that you converted a lurker from light bulbs to QB's. :)

    That's a fucking cool light.

    The engineering on these fixtures is nicer than the HLG kits. Aboot time someone started competing in this segment.

    In what way do you mean? Are you referring to the frame? It's my understanding that Timber is using HLG boards in these fixtures...

    As for this particular unit - it definitely looks nice, but I wonder why they didn't spread the boards out a little more. I'm not seeing anything about this unit that would make it a better option than the HLG600.

    Blah blah! Are you fixed on black?
    There is a 4040 profile where all 4 slates are mounted to. For my taste thats much too close together and will cause a hotspot.
    Two 24SAMS fixtures with at least 1' in between would be much better. That's the same problem I see with the HLG550/600.
    You need at least something like a frame to mounts the boards further apart from the next. @welight from Cutter also used such profiles(smaller 2020) but to make a frame for 4 boards, 1' spacings and he got much better uniformity, less center hotspot and corner brightness of ~80% of the center readings!
    Less hotspot means also you can hang the hole fixture closer to your plants without getting bleaching, less light loss on the walls is another benefit.
    Untill I see something similar I would rather build my own frame and take only the boards and slate heatsinks and maybe the drivers. These profiles are pretty cheap and it's realy easy to work with. You can get them also in black if you want, btw.

    Right on. I love my QBs, and I think HLG is awesome, but I really think they need to update their fixtures to spread those boards out more. Same goes for Timber.

    Pretty much this. HLG has great PCB, diodes and customer service. Their controls and fixture options are their areas for improvement and iirc they are fixing the former. If I were famous like Ledgardener and had Robin's ear at HLG, I'd be pointing that out as Timber is taking advantage of it. All the power to them for responding to a market need faster.

    Yea, I see the problem with the shipment of pre-assembled lamps, because with the size of a 36x 36" frame they would probably have to assign a forwarding company. However, you could disassemble a preassembled frame from 2020 profiles into 4 parts with only loosening 4 screws and the inner profiles are smaller anyway.

    I am pretty sure that such a frame would sell well and he would significantly improve the lamps uniformity.
