Wuben X4 In-Depth Review: A Flat Flashlight That Redefines EDC

Design and Structure

The Wuben X4 showcases the brand’s continued evolution in product design and positioning. Measuring just 96mm × 35mm × 26mm (including the pocket clip), it boasts a remarkably compact and portable form factor.

Crafted through die-cast aluminum alloy construction and finished with an upgraded oil-spray coating, the X4 demonstrates refined detailing compared to the earlier X2 Pro. Its dual-tone color scheme—off-white and black—contributes to a clean, modern aesthetic. The matte finish offers a smooth, premium feel in hand, though it is slightly prone to fingerprint marks.

At the top of the flashlight sits the main light unit, featuring four LEDs arranged behind a hybrid lens system: three optimized for throw and one for flood, achieving an effective balance between long-distance and wide-area illumination.

On the front of the body, the auxiliary light is housed beneath a translucent, embedded PC diffuser that enhances floodlight diffusion. The LED layout follows a 6+1 configuration—six white LEDs for close-up tasks, and one RGB LED capable of cycling through seven vibrant colors: red, orange, yellow, green, cyan, blue, and purple.

Controls and Configuration

The X4 features three sets of controls, all located on the left side of the body: a rotary switch, a mode slider, and a tactical tail button. The rotary switch integrates both rotation and press functions, the slider toggles between lighting modes, and the tail button serves tactical functions.

Before first use, remove the insulating film and insert the battery with the correct polarity as indicated. The X4 comes with a 3400mAh 18650 lithium battery, delivering 12.58Wh and up to 30 days of maximum standby runtime.

A strong magnetic base is integrated into the tail, capable of firmly attaching to metal surfaces and supporting the flashlight’s 140g weight for hands-free use in various scenarios.

Accessory Compatibility and Expandability

The X4 offers excellent compatibility with accessories. Owners of the X2Pro will be pleased to know that accessories such as the ARC helmet clip are directly compatible. The rear clip also fits standard helmet rails, allowing the X4 to function as a helmet-mounted light. It can be paired with a bicycle mount for use as a bike light. The soft diffuser cover is also fully compatible, ideal for soft, eye-friendly lighting during nighttime reading.

Moreover, the tactical tail switch is built directly into the X4’s body, eliminating the need for additional tactical modules and enhancing convenience.

Feature Highlights

1. Portability

The sturdy rear clip allows for easy attachment to a backpack, belt, or pocket, making the X4 easy to carry.

2. Battery Indicator

The mode slider toggles between Moonlight, Main Light, Side Light, and Lockout modes.
