I was just curious as if to I can run this flashlight (the rogue1) off a 14500 cell.
A 14500 li-ion works great in the Rogue I. From what I understand the Rogue I and II heads are interchangeable. Regardless, the li-ion cranks up the output and still maintains a low mode, although a little brighter than low on alkies. Also, there have been no ill effects and the light still works when switched back to Nihm on alkaline.
