Introduction
The “old” X1 was on my wish list for a long time, but for some reason, the timing was never right. When I received the offer from Wuben to review the X1 Pro, I didn’t hesitate for a second. On paper, this light is right up my alley!
However, when it comes to high-output lights—especially in a “compact” format—I’m always a bit skeptical about whether the specs are actually met.
Specifications by Wuben
You can buy the light directly from Wuben , you’ll find all the specs listed there as well.
There are two versions: an all-black one, which is the one I have here, and a white version with black accents.
Package Contents and Impressions
As with all Wuben ECL lights, it arrives in a blue and white box. Lifting the lid reveals the light, initially wrapped in a plastic bag. It’s held and protected by a plastic tray - this works well as my unit clearly didn’t have the easiest journey, and the tray was partially cracked, but the light itself was flawless.
Also included in the box are a user manual, a holster, a lanyard that doubles as a USB-C cable, and spare screws for the fan cover. Separately, there was a 1/4-inch thread adapter, which also serves as the adapter for the separately available bike mount.
The light itself is perfectly finished. The anodization is flawless with a nice satin-matte feel, and clearance between the parts is consistent throughout.
The laser engravings are crisp and nicely done.
The slider switch moves with
a pleasant resistance but clicks into place
firmly enough to prevent accidental switching.
The USB-C port cover fits snugly and all tested cables not only fit but functioned perfectly.
The side switch with its integrated battery indicator (100-90% blue, 90-40% flashing blue, 40-15% red, 15-0% flashing red) has a solid tactile click. You should definitely follow the label’s advice to use the 4-click lockout, or you’ll quickly end up with a hole in your pocket.
However, the switch and the port are so close together that my thumb often caught on the rubber flap. Not enough to pull it open, but enough to be noticeable. It’s a bit irritating but doesn’t affect functionality. And yes, especially with cold hands, it’s easy to confuse the USB-C port with the switch.
The light supports reverse charging and can be used as a power bank, which worked flawlessly in my testing.
The battery cover is lockable and pops open with quite some force when the release button is pressed. Underneath, you’ll find two 4800mAh 21700 cells.
On some units of the X2 Pro and X4, the latch supposedly broke. Now it is screwed on and thus replaceable—a very good solution in my opinion!
The glass has a purple AR coating, and underneath, the LEDs sit in some unusual reflectors:
The flood LEDs have “waves” at the upper edge, and the spot LED has them directly above the emitter. I’ve not seen such a pattern until now.
The bezel on top is cleanly screwed down and sits flush with the housing.
Underneath the LEDs, behind the switches, sits a fan. It is user-replaceable ans I hope spare parts will be available in the long run.
Either way, it’s great when a wear-and-tear part is replaceable
Size
Lumintop Mach V2, Sofirn ST2, Wuben X1 Pro, Olight Arkpro, Acebeam M1 Terminator
On my scale, the ligt weighs in at a hefty 378g including batteries - less than the factory specs, but more than it feels!
Dimensions: 138.5mm long, 48.5mm wide, and 28mm deep.
Carrying Options
Lanyard: A lanyard is included, which doubles as a USB-C cable. It’s a bit stiffer than most lanyards but feels like it can handle the light’s weight and works well as a cable.
Clip: There is no clip on the light itself, but there is one on the holster. It’s unusually exposing, but the light is easy to insert/remove and stays secure. A nice touch is that it’s rotatable, so you can change the orientation of the light.
Magnet: There is no magnet in this light.
(Jacket)pocket: The light is too big for my pants pockets, fitting only in the back pocket at most. However, the X1 Pro fits easily into cargo pants or a jacket pocket.
UI (Bedienung)
The UI is simple and intuitive.
The slider switch lets you choose between Flood, Spot, or all LEDs combined.
The push button turns the light on in the last used mode with a single click.
Hold from off takes you to the lowest mode. Hold while on cycles through modes in ascending order.
Single click turns the light off.
Double click activates Turbo from any state (except lock), which is the only mode not memorized.
Triple click activates Strobe.
4 clicks locks/unlocks the light.
To confirm the lockout, the LEDs selected by the slider flash twice. If you press the button while locked, it flashes blue 3 times
When unlocking, it always starts in the lowest mode.
5 clicks activates or deactivates the fan, unless the light has auto-activated it for thermal reasons - then it stays active whether you want it or not.
Beam Profile and Measurements
Short disclaimer: Due to the light’s shape, it’s a bit difficult to get accurate readings in my setup. The margin of error might be slightly higher. I determined the maximum values independently of the runtime tests with the most optimal positioning possible.
All runtime tests were conducted at 22°C ambient temperature without additional cooling.
Overall, I really like the beam pattern. In Spot mode, you can see a very slight tint shift in the center, but only on a white wall.
Aside from that, it offers a large spot with good reach, though it’s not a pure thrower.
Flood isn’t a pure mule-like flood.As expected from the small reflectors, there is a massive spot that transitions very smoothly into the spill. This is a great compromise, offering wide illumination with at least some reach.
When combining both, you get a defined spot with a very even, pleasant spill. It feels very harmonious and well-thought-out.
I’ve also put together a small beamshot comparison for you. All photos were taken with the same camera settings. The phone was mounted on a tripod, while the light was held by hand. All shots were taken immediately after turn-on.
The performance is solid, I measured a maximum of 11,500 lumens (12,300 are claimed). This is well within the margin of error. However, this only holds shortly after turn-on, as the light drops off almost immediately.
The real highlight, as with the original X1, is the sustained output. For a light this size, it’s impressive.
Finding a direct comparison for this light is tough, it’s quite unique. The only other compact, actively cooled light in my collection is the Sofirn HS45, but that’s a different size class. If you know of an interesting candidate for a comparison, let me know! If possible, I will add it here!
Regarding the Turbo runtimes, the individual operation of Spot and Flood is interesting. Looking at the temperatures, you can see the fan cycling on and off at the end of the runtime. So, there is active thermal regulation, and the fan helps the light stabilize around a target temperature.
Why does it look like it’s happening at different temperatures? Probably because the temperature sensor wasn’t aimed at the exact same spot. Speaking of heat: the fan is powerful enough to heat up my desk mat significantly—enough to show up clearly on the thermal camera, as seen on the right side of the following image.
To wrap things up, here is an overview of many of the available output levels. For the sake of clarity, I’ve left out Eco and the two lower Low modes, otherwise, the chart would have been a cluttered mess.
| specs by Wuben / my measurements | Eco | Low | Mid | High | Turbo |
|---|---|---|---|---|---|
| Flood+Spot | 20 / 20 | 400 / 365 | 1000 / 900 | 3000 / 2620 | 12300 / 11500 |
| Flood | 10 / 10 | 200 / 180 | 500 / 450 | 1800 / 1570 | 8650 / 8250 |
| Spot | 10 / 10 | 200 / 180 | 500 / 435 | 1200 / 1060 | 3650 / 3250 |
The deviations are quite consistent. I can’t rule out a 10-15% variance due to the light’s form factor. I’d trust Wuben’s numbers over mine in this case.
CCT reicht von 6000K in Eco bis 7000K in Turbo
CRI is around 70: 68 for spot, 71 for flood.
DUV ranges from 0.004 (Eco) to 0.000 (Turbo)—surprisingly no difference between Flood and Spot!
Flicker is mostly in the green. In flood-eco it’s nearly in the yellow. Accordingly, PWM is visible through a camera but not to the naked eye. From low onwards, it’s a non-issue.
Low Flood, Low Spot + Flood
Charging reaches nearly 30W in my setup. The charging curve is exemplary. The LED changes from red to blue before the process is finished, but it continues to charge at a rapidly falling 2W. Not much capacity is left on the table.

After removal, both cells were at 4.18V.
The capacity of the two batteries was significantly better than specified, both were measured over 5100mAh.
Summary
I tested the light for quite a while, including a vacation. It performed very well and showed no issues. On the contrary, it was a surprisingly reliable companion.
No extreme use cases, but wind, rain, snow, and cold didn’t bother it and the fan did its job inconspicuously.
Sure, there’s no High CRI, but for a light designed for output, that’s acceptable for me.
The beam profile is near perfect in my eyes, flood and spot work great individually and combined.
Ergonomics are good for me: switch down in the right hand, switch up in the left. That way I can easily reach both switches in any situation.
Bottom line: I really like this light! Am I perfectly happy? Not quite—if I had one wish, I’d love a tail switch similar to the X4. The shape of the light constantly invites me to hold it at shoulder height, where a tail switch would be the perfect addition. Maybe we’ll see that in a V2—until then, the X1 Pro will be getting plenty of use!
