Wuben X4-Redefined 18650 Flashlight

Meet the Wuben X4 

Crafted for those who demand both power and portability, the WUBEN X4 features a high-performance main light, a versatile side light, and integrated tail switch—all powered by a replaceable 18650 battery. Its dual-beam head, precise sliding controls, and hands-free functionality are packed into a sleek, easy-carry design.

Flood + Spot, At the Same Time

Equipped with four high-performance LEDs, the X4 delivers both flood and spot beams—simultaneously. Light up your surroundings while focusing on what’s ahead, with over 1500 lumens of customizable output. Perfect for any situation that demands both wide visibility and long-range precision.

Versatile Side Light 

Featured 6× 4000K warm white LEDs with stepless brightness adjustment from an ultra-soft 1-lumen moonlight mode all the way up to 100 lumens. Whether you’re reading at night or lighting up your tent, you’ll always have the perfect level of light.

7-Color RGB

X4 isn’t just about brightness — it’s about versatility. Equipped with a built-in 10-lumen RGB light, you can easily switch between 7 vibrant colors using the rotary dial, making it perfect for ambient lighting, night visibility, or creative use. Need to attract attention or stay safe? Activate the flashing signal mode for instant visibility in emergencies or low-light environments.

Intuitive Control

With its unique push-plate and rotary button combo, the X4 offers a more portable and user-friendly way to operate your light. Effortlessly switch modes, adjust brightness with precision, and activate one-click lockout for daily carry confidence.

Innovative Tactical Switch

Unlike traditional tail switches, the X4 uses a cleverly integrated side-mounted control that’s both ergonomic and instinctive. Whether for everyday tasks or high-stress situations, it ensures quick, reliable activation—no fumbling, no delay.

Ultra Portable Sized

To achieve true pocket-level portability, the X4 adopts a new, high-precision manufacturing process that pushes the limits of compact flashlight design. Every millimeter is carefully engineered, resulting in a sleek, rectangular form that slips easily into your pocket—smaller than most 18650 flashlights, yet powerful enough for daily and emergency use alike.

Ready for Anything

Built with portability and ease of use at its core, the X4 stands upright, attaches magnetically to metal surfaces, and clips securely to your gear. Whether you’re fixing, hiking, or just need both hands free, the X4 is always ready—no hassle, no compromise.

Replaceable 18650 Battery

Experience prolonged illumination with the high-capacity 3400mAh 18650 rechargeable battery. Its replaceable design ensures flexibility and longevity, making it ideal for both everyday use and outdoor adventures.

Type-C Charging

Effortlessly charge your flashlight via USB-C, while the integrated RGB LED provides real-time battery status—offering a smart, stylish, and intuitive charging experience.

Bike-Ready

Transform your X4 into a powerful bike light with the optional bicycle mount. It’s easy to attach and remove, making night rides safer and more convenient than ever.

Red Light Mode

Available as an optional accessory, the detachable red diffuser softens the beam to preserve your night vision — perfect for camping, stargazing, or tactical scenarios. It reduces glare, minimizes light disturbance, and helps you stay discreet in dark environments, all while being easy to attach or remove as needed.
