I've got a Pace 400, which is the version of the Expilion sold by Perfromance/Nashbar. Very happy with it. I usually run it at 300 lumens and just bump it to the full 400 when I need it on an unlit trail. I get between 2 to 1 1/2 hours out of it this way. Usually last me for a full ride, but I carry a spare battery just in case.
On the battery question, it is an 18650 in a proprietary casing.
