Review: Klarus XT12S, a multipurpose

The XT12S is a mid-size duty/utility type flashlight with magnetic charging and dual tail switches using a single 18650 battery. It offers shortcuts from off to high and low (or strobe). Its output falls well short of the advertised 1600 lumens, some modes have visible flickering and audible noise, and my sample was not waterproof. The concept isn't bad, but the execution could use some work.
