Wuben X4 Review: One Flashlight That Does Almost Everything

Introduction

Wuben has built a reputation for affordable designs that explore features other flashlight makers tend to skip, and the X4 is the latest example. It looks complex at first glance, but after a few minutes of use the control layout makes sense. This is a light that tries to be many things at once: a cap light, a reading light, a signal light, a 1500 lumen torch, and a moonlight lamp, all in one solid aluminum body.

Who This Light Is For

The X4 is aimed at people who want a single carry light that can do a little of everything. If you want one dependable flashlight for daily carry rather than a specialized tool for one job, this design philosophy fits well. The only clear exception is tactical use, since there is simply a lot going on with the controls.

Main Strengths

Charging is handled through USB-C with a cable included, and the battery compartment is genuinely useful. A small locking mechanism snaps down, a button pops the sealed O-ring compartment open, and inside is an included 3350 mAh 18650 battery. You can carry a spare or recharge it, which is far better than being stuck with a sealed cell.

The body is solid aluminum with a fairly deep, thick, wide carry pocket clip that also works well for attaching the light to a hat. A magnet in the body lets you stick the light to metal surfaces, and a tail switch gives you instant access to the full 1500 lumen output with a single press.

Brightness control is a highlight. The side button toggles through brightness levels, and a small thumb wheel gives you stepless adjustment. Slide it to the top and you get a proper moonlight mode, which the reviewer considers essential for quick, low-glare tasks at night. There is also a physical hard lock that completely shuts the light down, a feature many people now ask for because it removes the risk of accidental activation in a pocket or bag.

The Side Light and Color Modes

The side light panel is where the X4 gets creative. One press turns it on, and the thumb wheel adjusts its brightness steplessly. Double clicking cycles through red, blinking red, and pulsating red. Holding the button brings up blue, red and blue, red and green, red and white, and off.

These color modes make the X4 practical as a signal light or a night-friendly reading light where preserving dark adaptation matters.

Things to Consider Before Buying

The tail switch behavior deserves a mention. In lock mode the tail switch does nothing, which prevents accidents. Once unlocked, the tail switch gives full power, but if you slide the control to moonlight, the tail switch also respects moonlight. That means you will not accidentally blast your eyes with full brightness when you expected a low glow, which is a thoughtful touch.

The spec plate lists turbo output and stepless brightness from 5 lumens up to 1500. Run times stretch into days, weeks, or even months depending on how much you use the light.

Buying Advice

If you want one good solid light that handles everything from a cap light to a reading light to a signal light to a 1500 lumen torch to a moonlight mode, all with a replaceable rechargeable battery, a magnet, a tail switch, and stepless push-button brightness, the X4 makes a strong case. It is not the light for tactical use, but as the everyday light you grab for a bit of everything, it is genuinely impressive.

Conclusion

The Wuben X4 rewards time spent with it. What looks busy on paper turns out to be an intuitive, versatile, well-built light that covers an unusual range of everyday tasks without asking you to carry anything else. For anyone after a do-it-all EDC flashlight, it deserves a close look.
