I think you told us the runtime on the 450-lumen XP-G before, but I forgot.
I used AW2900 Mah battery for my runtime test. At 1.5 hrs of continuous run, the light was still very brght with the battery reading at 3.48 volt. At 2 hrs, there was some drop in lumens and the battery was at 3.2 volt. I'll say it is good for at least 1.5 hr to 2 hours.
