WUBEN X4 EDC Flashlight Review

Name: WUBEN X4 EDC Flashlight
Brand: WUBEN

A flat 18650 pocket light with a rotary dimmer and an RGB side light. It competes with the Olight Arkfeld line, Nitecore's EDC series, and Wuben's own X0, X1, X2 and X3. Its pitch is the battery: a standard 18650 behind a hinged door, in a class where the cell usually comes built in and stays there.

The verdict

Direct answer: The Wuben X4 is a flat USB-C pocket light with a removable 18650, and I own one. 1Lumen's meter read 1,460 lumens at turn-on and 178 meters of throw against the 1,500-lumen, 205 m claim, and called it a winner. The catches: about 64 CRI on the main LEDs (BudgetLightForum's Opple reading), and a turbo that starts fading the moment it turns on and settles near 470 lumens. The number on the box is true for about as long as it takes to read this sentence. Update, October 2026: after months of abuse the clip by the battery snapped, and Wuben replaced the part immediately. I would buy from them again.

WUBEN X4 EDC Flashlight

For: one flat pocket light that covers throw, flood and camp lighting, with a cell you can swap and USB-C on board. Versatility over beam tint.

Skip if: accurate color matters to you, or you need high output that holds. The X4 reads about 64 CRI and steps down from turbo within seconds.

Update, October 2026: it broke, and Wuben fixed it

It broke. After quite a few months, and after crazy amounts of torture. My brother works in low voltage and has been using it nonstop. Eventually the little clip by the battery snapped, and the battery would not stay in.

A scuffed white Wuben X4 held in a hand, paint worn through at the edges, battery door open and clip on the side — My X4 after months in my brother's hands: dropped, scratched, battered and beaten.

The Wuben X4's hinged battery door flipped open, showing the spring, above the slide switch — The battery door, open. The little clip by the battery is what snapped, and Wuben replaced the part.

In defense of the X4, it had been dropped, scratched, battered and beaten, and treated like the adopted child for quite some time before it gave in.

What Wuben did. They replaced the broken part immediately. Considering the beating it took and kept getting up, as well as the customer service of them standing behind their warranty, I think it was a good purchase. I would definitely purchase again from that brand.

Whose numbers these are I own this light and paid retail for it. The measurements on this page are 1Lumen's, ZeroAir's and BudgetLightForum's, not mine, and each one links to its source.

What independent testers measured

1Lumen bench review: 1,460 lm at turn-on and 1,053 lm at 30 seconds, against 1,500 claimed. 7,950 cd, which works out to 178 m of throw against 205 claimed. Output starts ramping down at once and settles near 469 lm at ten minutes. The ANSI turbo runtime came in at 3 h 30 min, beating the 3-hour spec. 1Lumen called it a winner.
ZeroAir Reviews: 839 lm at 30 seconds and 8,045 cd. Knocked the low CRI, the missing modes between moonlight and turbo, and the angular body. Praised the hinged 18650 cover and called it a good take on a standard 18650 light.
BudgetLightForum (worrub918's review): Opple meter readings of 64 CRI on the main LEDs and 77 CRI on the side COB, with a greenish tint on low. Found the 1,500-lumen claim credible. The light survived an intentional 1-meter drop. Flagged the tail switch, which sticks out a little and wobbles when the light tail-stands.
The Gadgeteer: found the four-LED main beam a useful mix of spot and flood. The flat body sits well in a pocket, with a stout, mostly deep-carry clip.
Wuben official X4 product page: the spec source. 1,500 lumens, 205 m beam, IP65, user-replaceable battery, USB-C fast charging, magnetic base. Wuben's own page says the battery is user-replaceable, so the marketplace listing bullet that calls it sealed is wrong.

Pros and cons

What works

Real output for a pocket light. 1Lumen measured 1,460 lumens at turn-on and about 178 meters of throw from a single 18650.
The battery is a standard 18650 behind a hinged door. ZeroAir and BudgetLightForum both singled it out. When the cell fades, you swap it instead of retiring the light.
The stepless rotary dimmer and the slide switch give fine control over brightness. The RGB and 4000K side light covers the tent, the campsite and the map without a second light.
Turbo runtime beat its own spec in 1Lumen's ANSI test: 3 h 30 min measured against 3 h claimed. USB-C charging is on board, and the magnetic tail holds it to steel for hands-free work.
Wuben stands behind the warranty. When the clip by the battery snapped after months of abuse, they replaced the broken part immediately.

What doesn't

Low color rendering. BudgetLightForum's Opple meter read about 64 CRI on the main LEDs, with a greenish tint at low levels. If you notice tint, you will notice this.
Turbo does not hold. 1Lumen saw output ramping down the moment it turned on, settling near 469 lumens at ten minutes. ZeroAir's 30-second reading was 839 lumens. The 1,500 on the box is a moment, not a mode.
Four controls on one pocket light is a lot to learn. And the Amazon listing's own copy describes the battery as sealed and non-removable. It is not.
The angular body is less comfortable in hand than a round tube (ZeroAir), and the tail switch sticks out enough to make tail-standing wobbly (BudgetLightForum).
The clip by the battery can snap. The one my brother uses did, after being dropped, scratched, battered and beaten for months. It gave in late, but it gave in.

Common questions

Is the Wuben X4's battery replaceable?: Yes. The Amazon listing copy says sealed and non-removable, but the X4 uses a standard 18650 behind a hinged door. A 3,400 mAh button-top cell ships inside, and it takes flat-top or button-top 18650s. 1Lumen, ZeroAir, BudgetLightForum and Wuben's own site all confirm it.
Does the Wuben X4 really put out 1,500 lumens?: Only at the instant it turns on. 1Lumen measured 1,460 lumens at turn-on, 1,053 at 30 seconds and roughly 469 at ten minutes. ZeroAir's 30-second reading was 839 lumens. Treat it as a 470-lumen light with a brief turbo punch.
How long does the X4 take to charge?: 1Lumen measured about 3 hours 7 minutes over USB-C at an 11.65 W peak, well past the 1.5-hour claim in the Amazon listing. Moonlight mode runs while it charges.
Does Wuben honor its warranty?: In my experience, yes. When the clip by the battery snapped on the X4 my brother had been using nonstop, Wuben replaced the broken part immediately. That, and the beating it took before it gave in, is why I would buy from the brand again.
