The Wuben X4 might just be the most versatile flat-style flashlight I’ve tested.
With a 4-LED TIR array, RGB and warm white work lights, a sliding mode selector, an infinitely adjustable brightness dial, a tactical tail switch, and a replaceable 18650 battery, this light is built to last for years.
In this review, I test the X4’s build quality, beam performance, UI, and practicality after a week of use.
