Built this COB led enclosure using a AMD AM4 Wraith prism cooler as the heatsink, I have a 20w Cob LED on here but it could almost certainly handle a 30w and possibly more (might need to cut out some of the frame if the cob is bigger.

Build the power board as a separate piece so it could easily be made for other slightly different sized boards

Includes a ¼ tripod mount, could either remix it or just drill it out to put in a heat set ¼ insert if wanting it to be more robust
