Review: Acebeam TK16 - a small EDC triple with a tail e-switch and high CRI

The Acebeam TK16 is a 1x16340/CR123A everyday carry light with three emitters and a tail e-switch. It resembles a cross between a Lumintop FW3A and an Olight S1. It combines excellent power efficiency, class-leading max output, and very good color rendering.
