Wuben X4 Hands-On Overview: A 1500-Lumen EDC Flashlight with a Clever Three-Light Design

Introduction

The Wuben X4 is a compact EDC flashlight that tries to do more than one job, and for the most part it succeeds. Rather than offering just a single main emitter, it combines a 1500-lumen flood-and-spot main light, a warm white sidelight, and an RGB sidelight in one body, all managed through two switches and a rotary dial.

There is one important caveat: the X4 is still a Kickstarter project, so this is an overview rather than a long-term review. The good news is that the early bird tier is still open at around $45, which makes it an interesting option if the feature set matches what you need.

Who This Product Is For

The X4 suits anyone who wants a genuinely versatile everyday flashlight rather than a one-trick bright light. If you value a usable warm sidelight for close-up tasks, RGB modes for signaling or night-vision-friendly work, and a removable rechargeable battery, it covers a lot of ground in a 5 oz package. It is less relevant if you only ever need a simple, single-mode light.

Key Features and Specifications

Wuben lists a maximum output of 1500 lumens, a maximum throwing distance of 205 meters, a maximum intensity of 10,500 candela, and a maximum runtime of 720 hours, which works out to 30 days. That longest runtime comes from the 1-lumen warm sidelight mode rather than the main light.

The main light uses four LEDs that deliver flood and spot at the same time. Inside is a 3.7V 3400mAh 18650 rechargeable battery, charged through a USB-C port on the side of the light or via an external slot charger. The battery sits on a dual spring system, and the light carries an IP68 rating, meaning it is fully dustproof and submersible in up to 6 feet of water, with 1 meter of impact resistance.

Dimensions come in at 3.77 x 1.47 inches with a thickness of 1.04 inches, and the light weighs exactly 5 oz (140 g) with the battery installed. The package includes a Wuben-branded lanyard and a USB-A to USB-C charging cable. An optional red silicone cap, listed at around $2 on the campaign, fits over the head to soften the beam and preserve night vision.

Design, Build and Handling

The X4 is thoughtfully laid out. There is a side switch on the body and an integrated tactical tail switch at the rear. That tail switch is a highlight: it remains flat on the bottom so the light can be tail-standing, it has a satisfying clicky action, and it supports both moonlight mode and instant turbo.

The magnetic tail is another strong point. The built-in magnet is strong enough to hold the light horizontally or vertically on any steel surface, which is not something you always see at this size. A steel pocket clip rounds out the carry options.

At the tail there is also a battery lockout switch. Slide it and the door opens to reveal the button-top 18650, then slides back down to lock the compartment. Like the Wuben G5, the X4 also has a sliding door on the body with multiple functions, including a full electronic lockout of the flashlight.

Three Light Systems in One Body

The X4 runs a three-mode control system. The main white light handles distance and brightness, the warm white sidelight uses six LEDs at roughly 4000K and runs from 1 lumen up to 100 lumens, and the RGB sidelight offers seven different colors at 10 lumens each.

The sidelights are where the X4 gets genuinely interesting. The 1-lumen warm moonlight mode is what delivers that headline 720-hour runtime, and the warm tone is far more pleasant for close-range tasks than a harsh white beam. The RGB side supports a beacon mode and flashing combinations in red, blue, red-green, and red-yellow, all at 10 lumens. There is also a proper white strobe function on the main light, which is a nice touch since the beacon itself is RGB rather than white.

One observation worth noting: during use, the sidelight warmed up in the hand noticeably faster than the main light did even at turbo, which is worth keeping in mind if you plan to run the sidelight at its full 100-lumen output for long stretches.

User Interface and Controls

The UI is fairly simple once you learn the sliding door and the two switches. Sliding the door all the way down locks out the flashlight completely. One step up activates the sidelight, another activates the main front light, and one more gives instant access to moonlight from either the side switch or the tail switch.

In main light mode, the rotary dial steps through brightness levels from 5-lumen moonlight up to the 1500-lumen turbo. It is a stepped system rather than fully smooth ramping, and there is a noticeable jump between moonlight and the first step. A single short press turns the light off, and the light remembers your last brightness level when you switch it back on.

The tactical tail switch provides momentary-on that jumps instantly to 1500 lumens, and a double press triggers strobe. In sidelight mode, the dial adjusts warm white brightness from 1 to 100 lumens, and in RGB mode the dial cycles through the seven colors. Press and hold the side switch to enter RGB, double press for the flashing beacon, and double press again to return to a solid color. The flashing modes are reached by double pressing from off.

Beam Profile and Real-World Performance

The beam profile is one of the best the X4 brings to the table. The four-LED main light throws a genuinely useful mix of flood and spot at the same time, lighting up both near ground and distant targets. In testing, the beam easily reached a tree and a barn at distance on turbo.

Independent lumen testing tells a slightly more grounded story than the spec sheet. Moonlight measured exactly at the claimed 5 lumens, which is spot on. Turbo measured around 1400 lumens against the claimed 1500, but it began stepping down immediately. Over roughly a minute it descended to about 458 lumens, where it held steady for the remainder of a two-minute test.

That thermal step-down is normal for a light this size, but buyers should expect real sustained output closer to 450 lumens than 1500. The listed 3 hours at 1500 lumens on turbo should be treated with skepticism for the same reason.

Buying Advice

At the current Kickstarter early bird price of around $45, the X4 offers an unusually complete feature set: a strong main light with a great beam profile, a genuinely useful warm sidelight, RGB versatility, a removable 18650 battery, USB-C charging, magnetic tail mounting, and IP68 durability. The earlier super early bird tier at under $40 sold out quickly, which suggests demand is real.

If you need a single-purpose bright light, a simpler option may serve you better. But if you want maximum flexibility in one compact, well-built body, the X4 is an easy recommendation at this price, provided you go in understanding that the 1500-lumen figure is a short burst rather than a sustained output.

Conclusion

The Wuben X4 stands out for its three-light design and excellent flood-and-spot beam profile, backed by practical details like a magnetic tail, dual-spring battery contacts, and a true lockout system. Turbo output drops quickly from roughly 1400 lumens to a steady 458, but the early bird pricing makes that trade-off much easier to accept. For anyone after a versatile EDC flashlight with more personality than the average torch, it is well worth a look before the campaign ends.
