I can't imagine any of this being easy on account of your paws!
Off to a great start there. The welding stuff is way over my head but looks impressive. You have thermal paste under those directly on the aluminum as well?

Thanks and yes there is thermal paste under each LED.

Nylon screws sound good until you need to tap. Plus they are know for slightly backing off over tim due to expansion/contraction of the heatsink. Then your stars don't have good connection to the sink and all h*!l breaks loose. Things are looking great on here though!

While I wait for my new washers I thought I'd work on setting up and testing the rest of the electronics and it seems I've found an issue. The 24V power supply won't put out more than 14V, the lowest is 10V. I would have expected a range of about 20-28V so I'm thinking something maybe half of something isn't working properly. Anyone familiar with this?

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.
