Some updates:
Covered the inside of the canopy with aluminium tape
Installed fixture and setup heat tests, this is operating at 100% on all LEDs except the yellows which I haven't gotten working yet (might be driver issue).
Hottest point I could find was at 113F according to this measuring device, other methods I used were not over 100F. This was taken after about an hour of steady state. I also doubt I'll be anywhere near 100% power, 50% is more likely closer to my lighting needs.
The test was not done without fans, without the fans I suspect it will reach well over operating temp with this many LEDs at 100%. Once the fixture is done I will do some more testing but I think I'll be installing a thermo switch to protect the LEDs from overheating in the event of fan failure.
