Hi, after a few years in limbo I am wanting to build the K4 Saber Kit of Obi-Wan Kenobi's saber. I have been trawling the forum for hints, but haven't found what I am looking for. I have read that it takes a 20mm speaker, but what size LED Base does it need? Also does it need a standard heatsink for the LED or does one come supplied? I would be trying to put a tri Cree XP-E2 in. Does the base need to be modified, or does it take a standard base size?

Any help would be greatly appreciated, thanks
