I recently received a request to convert a McLux PDIII to a Mule. This was the perfect opportunity to use my new lathe to turn down some aluminum. I made a heatsink that was the same external dimensions as the McR20 reflector, mounting the Nichia 219 LED close to the window. Some Arctic Silver thermal compound helps with the heatsinking, though the mass of the heatsink itself is likely more than enough.
