Wuben X1 Pro 2 Flashlight Review
The Wuben X1 Pro 2 flashlight uses five Cree XHP50.3 emitters (4 HD, 1 HI) (with charging improvements!) and removable, standard 21700 cells (2). Read on!
Official Specs and Features
Here’s a referral link to the Wuben X1 Pro 2 flashlight page.
Versions
There’s a black body version and this white (probably MAO) version. I believe performance (emitters, etc) between the two is identical.
Price
The current price for this Wuben X1 Pro 2 flashlight is $139.99. It’s available from Wuben directly (referral link), but it’s also available on Amazon (also a referral link).
What’s Included
- Wuben X1 Pro 2 flashlight
- Wuben 21700 (2, standard)
- Lanyard/charging cable
- Mount
- Manual
Package and Manual
Build Quality and Disassembly
The Wuben X1 Pro 2 flashlight is another in the line of rectangular lights from Wuben. This one is similar, of course, to the X1 (not pro), which I reviewed years ago, and is nearly identical to the X1Pro.
The build quality is good.
The cells are in series, so you need to carefully orient them according to these little icons in the tailcap.
There are also icons on the other end, inside the light.
In particular, the latch that holds the cell door seems robust and secure. I expect it will last! The latch may be locked as well, which I appreciate.
Size and Comps
59.6mm x 29.5mm x 138mm and 383g with cells.
This light can tailstand and headstand. It’s very rectangular, obviously.
Here’s the test light with the venerable Convoy S2+. The version below is a custom laser-engraved Convoy S2+ host by GadgetConnections.com. I did a full post on an engraved orange host right here! Or go straight to GadgetConnections.com to buy your Convoy S2+ now!
Also in the photo above, my Standard Reference Material (SRM) flashlight is the Hanko Machine Works Trident, an 18350 light. While I have not reviewed or tested the Gunner Grip version seen here, I have tested a Hanko Machine Works Trident Total Tesseract in brass. I love the Trident, and it’s a striking contrast to the inexpensive Convoy S2+, another great SRM.
Retention and Carry
The Wuben X1 Pro 2 flashlight has a lanyard loop on the hinge side of the tail end.
That little bulgy bit near the loop seems to be metal.
Wuben also includes this “1/4″ Thread Extension Spacer.” This is an attachment that adds a 1/4″ thread port to the light. You’ll be able to mount the Wuben X1 Pro 2 flashlight on a tripod with this attachment, for example.
Clearly, it attaches to the side, though!
That attachment is not needed for connecting the Wuben X1 Pro 2 flashlight to this Velcro holster.
Power and Runtime
The Wuben X1 Pro 2 flashlight runs two 21700 cells. They are included and standard. They’re also run in series!
If you forget to look at the icons on the tailcap, the spring orientation should give you a clue to how to input the cells. If only one end has a spring, it is almost always for contacting the negative terminal of a cell. And that’s the case with this Wuben X1 Pro 2 flashlight, too.
Below are a number of runtime tests. The light tests consistently lower than the claim, but it’s still very bright. Each of thie Turbo modes has a significant stepdown.
The temperature lines in these charts are included as general context, not precise measurements. The values represent the range (min to max) during testing, but should not be taken as exact readings. Temperature sensors are attached; however, not always on the bezel or hottest spot (assuming that can even be clearly defined). Even with ideal placement, too many variables affect temperature to definitively state a specific max value.
All the tested modes did seem to exhibit low voltage protection.
Charging
The Wuben X1 Pro 2 flashlight has on-board charging. There’s a USB-C port on the head.
Printing near the head indicates this light has PD charging, so if you have a high-quality PD power source, you can charge at high voltages.
And that’s just what I observed. With a PD power source, the Wuben X1 Pro 2 flashlight charges at 20V and completes in just over 2 hours. That’s pretty remarkable! On a 5V source, charging takes much longer, at just under 5 hours (not slow at all!).
Powerbank
The product page says the Wuben X1 Pro 2 flashlight has a powerbank. I’ll try to get that tested and add the data here.
Modes and Currents
| Mode | Mode Claimed Output (lm) | Claimed Runtime | Measured Lumens | Tailcap Amps @8.4V |
|---|---|---|---|---|
| Turbo – Both | 13000 – 5000 – 3000 | 1m + 1m + 1.7h | 9265 (0s) 6517 (30s) |

| High – Spot | 1200 | 4h | 991 | 1.04 |
| Med – Spot | 500 | 11h | 422 | 0.34 |
| Low – Spot | 200 | 28h | 173 | 0.12 |
| Eco – Spot | 10 | 455h | 8.9 | [low] |
Pulse Width Modulation
The order here is just as the switch presents the modes. Spot is the first row, both is the second row, and flood is the third row. Nearly all modes exhibit some type of modulation, but it’s fast enough that it’s unlikely to be bothersome.
Click here to see a “baseline” – a chart with almost no light hitting the sensor.
Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.
User Interface and Operation
There are two ways to interact with the Wuben X1 Pro 2 flashlight. First is the selector switch. As seen below, the leftmost option is spot. In the middle (selected) is both, and on the right is flood.
Once you select the mode you want, the output levels are changed with this indicating e-switch near the charge port.
Frankly, I had a hard time finding the switch without looking. There’s an indicating feature in the center of the switch. I do like the switch, though, since it has a hard cover and low action.
Here’s a user interface table! You don’t have to select the mode before you turn on the light – the selector works after the light is on, too. In that case, the level is remembered as you move from flood to spot to both, etc. (That’s the preferred way!)
| State | Action | Result |
|---|---|---|
| Off | Click | On (Memory, excluding turbo) |
| Off | Hold | Eco |
| On (excluding strobe) | Click | Off |
| On | Hold | Mode advance (excluding turbo) |
| Any | Double click | Turbo |
| Turbo | Double click | Previous level (except off) |
| Any | Triple click | Strobe (without memory) |
| Strobe | Triple click | Strobe advance (SOS > Strobe) |
| Strobe | Click | Previous state |
| Any | Click 5x | Iterate fan on/off |
| Off | Click 4x | Lockout (blinks a number of times to indiate lockout) |
| Lockout | Click | Switch battery indicator |
| Lockout | Click 5x | Unlock to Eco |
LED and Beam
The Wuben X1 Pro 2 flashlight uses five Cree XHP50.3 emitters. The four flood emitters are of the HD variety (domed), and the spot emitter is a HI (high intensity – no dome). They each have a reflector.
LED Color Report (CRI and CCT)
Regardless of mode or level, the CCT is high, and the CRI is low.
CCT (Correlated Color Temperature) refers to the measurement of the color appearance of light, expressed in Kelvins (K), which indicates whether the light is warm (yellowish) or cool (bluish). A lower CCT (below 3000K) is considered warm light, while a higher CCT (above 5000K) gives cooler, bluish light.
CRI (Color Rendering Index) is a measure of how accurately a light source renders colors in comparison to natural sunlight. Scored on a scale from 0 to 100, higher CRI values indicate that colors appear more true to life and vibrant, similar to how they would look under the sun.
Beamshots
These beamshots always have the following settings: f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.
Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)
I keep the test flashlight on the left and the BLF-348 reference flashlight on the right. These photos are taken around 18 inches from the door.
I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!
Summary and Conclusion
The Wuben X1 Pro 2 flashlight is a big flashlight with big numbers. It doesn’t seem to hit the claimed numbers, but they’re still big numbers. I even like some of the big numbers – like 4 hours at 1000 lumens! I appreciate that this version has removable and standard 21700 cells, and for this updated version, charging seems to have been improved (i.e., no overcharging issues). The user interface is simple and friendly, and the selector switch makes things even simpler.

^ Measurement disclaimer: Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.
What I like
- Great build quality
- Uses standard 21700 cells
- The user interface is easy to grasp
- Selector switch also doesn’t complicate anything within the user interface (it’s friendly, too)
- Hours and hours at 1000 lumens!
- Great MAO finish/color
- Big capacity as a powerbank
What I don’t like
- Low CRI
- High CCT
- Output didn’t hit the specification

What’s the X1 Pro 1?
I take this one to be the X1 Pro.

But isn’t that the same model, just as a pre-release version?
I’m nearly sure I saw Wuben refer to this as the “2” but now seems to be called the “2026” version. So I’m not sure. The manual is a bit different (with specifications lowered for output, for example.)
