gchart, you are right on. I used my needle-tip tweezers and the entire pill came out of the head no problem. Can’t say for sure but it looks like the internals/driver is potted. the XPG2 is nicely exposed on the business end; looks to be mounted on an 8mm aluminum PCB. I wonder if there would be any issues by using a slightly thicker copper or DTP type pcb…

I believe XPG2/219/sst20 all are 3535 footprints and utilize the same or close enough reflector insulator/spacer to interchange, correct?
