This Fenix Flashlight might be pint-sized, but it's far from dainty in performance. It pumps 130 lumens out of it's small aluminum frame - perfect for locating your ride in a dim parking lot, or finding a fumbled wallet in the dark. It runs of a tiny included 1018 rechargeable Li-Ion battery, and better yet, can recharge with the same micro USB cable you use for your smartphone (cord not included). IP68 rated waterproofing - meaning it stays watertight in up to 4-1/2' of water for 30 minutes.
