i can see those boards running cool with that diode placement especially when underdriven. how many watts each board pushes in your application?@crimsonecho the FOTOP boards talked about earlier ran pretty cool temps without heatsink.
The diodes on them are more spread out than QB288s.
I'm still using them.
Diy FOTOP grow board 280x900x2.0mm (L29.52"xW9.18")
I got these to test. Grow Board 280x900x2.0mm (L29.52"xW9.18") , 3.0/W conductivity,2OZ, 16S50P, 129.6-372W, 43.2-49.6V, 800pcs Samsung 561C s6 leds. They cost an "O" for 2 boards....... £200. Awaiting HLG 320H 48A from TME, cost a "q" ....£80 In my area I can use these as a side wall of...www.rollitup.org
Here's quality heatsinks I got for 2ft strips a few years ago from diyleduk. I believe he had 4ft ones too.
They fit any 2ft strip.

yeah i heard that but dont have black tape atm but i really feel zero heat when i touch it either i just feel the coldness of metal if that makes sense to youPlace a bit of black tape on aluminium and take ir reading

would you say taking an ir reading directly off the cobs the way i did it would give a ballpark reading?
