Review: Armytek Prime C2 Pro XHP35, a versatile 18650 EDC light

The Armytek Prime C2 Pro XHP35 is an 18650-powered EDC light with 8 brightness levels, shortcuts to low, medium, high, and last-used from off, a removable magnet in the tailcap and a choice of color temperature. It only has one major issue: the optic it comes with was not designed for the LED it uses, resulting in terrible output and efficiency. A third-party optic fixes this.
