I ordered it last month with a Terra Mule so I would assume it is his latest XPG-2. It is 3 stage converter and capable of 3v because I told Don it was for a Haiku. Light has never been carried. I couldn't decide if I liked the 2x123 or the 2x14500 for my Makai or if I wanted 3v or 6v so I ordered them all to experiment! My loss is your gain!
