For heat sinks you could put a piece of aluminum channel on each strip probably, two 3/4" inch ones maybe for a 3 fin heat sink. If it works when tested, I would use thermal epoxy to avoid screws and drilling. It would be on there forever though so you'd have to know for sure it will work before actually epoxying them on.

Sorry, trying to get more stock asap. These are not just boards, we put lots of time and thought into design and latest diodes. Lot more cool Heatsink and cost effective cooling solutions are coming out next month. Thanks
Added photos but still need to update numbers as these QB288 are 54V boards

you've got the wrong performance specs listed for the 288 board, its the 100V chart instead

Make sure you dont let too much light get out the windows ..... Airplanes may end up on your lawn.

Really would like to see single board heat sink for 2100mA and higher. Being 54v it does open up some driver options for series connection. I'll use the hlg240 2100 per 2 boards.

320w in a 2x4(8sqft) seems fair to me. About 20 par watts per sqft. Plus it can be turned down. I probably would of used 3 boards though.

In my setup the same wattage was almost too much for 12 sq ft. He could easily light 16 sq ft with it.
Don't tend those plants near bedtime or you'll never get any sleep!

Well 320w in 16sqft would be revolutionary. That is a huge leap in tech if that is the case. 300% better than HPS and 200% than cxb COBs.

If the grower wants a lot of light, go with 12 sq ft. If they don't need that much intensity, 16 sq ft is absolutely workable.
