20171021_160213.jpg @robincnn, I appreciate your insight. Are you saying that this issue is only on the 288 side and not the 304 side? Turned down, I temp'd the side that hangs off the heatsink at 105-109° the side that is on the heatsink at 103-107° usually only 2° higher. I turned on rig up all the way to 300 watts and the temps go from 135 to 125, If that is too hot, or just the non support issue is an issue,what do you suggest to cut them in half? Would a bandsaw and jig be ok? I have the boards turned down right now but could run them as high as 230 watts. I also thought of adding a piece of flat aluminum that would cover both the exposed boards and act as a heatsink...? It could evolve to be similar to growmau5 quantum canopy. Reds, blues, UVs...oh my, Lol.

If you want to drive those boards any harder, you'd want to make sure the heat sink covers the entire back of them. The easiest and least expensive way to do that would be to cut your best sinks in half and mount the boards to them so there's no overhang. Then you can use L shaped aluminum channel it some such to mount the heatsinks further apart to get the improved light distribution you're looking for.

That your system is working well like this is testament to the safety factor HLG built into their equipment.

Will there ever be an option to add out of stock boards to your cart buy them and just wait for your order in a queue ?
Like i would rather buy my boards and know that it will be 2 months before i get them rather then hope i have enough in my bank account for the short 2 hour window when they are in stock and miss it repeatedly :P

Love to see the QB120 showing up in more builds! I've posted this in another thread, but I'll just throw it up here, since we're on the topic. Long live the mighty mite!View attachment 4031009

I would too.

@robincnn can you update the specs on the website for these boards? make a chart like the other boards. I see they can be run from 10 to 60 watts and 11x9.5 in size. But do you have any LM/W stats, umol, etc?

FV per board? 24v?

Thanks!! So they don't need heat sinks? even running at 60 watts?

Is there any reason these couldn't be used like normal q boards? if you put 12 of them over a 4x4 running 50 watts, that seems like it would do great.
