The Wuben X1 is the bigger brother of the Wuben X2 and it is capable of producing 10,000+ lumens.

It even has a fan with a heatsink to keep it cool!

Wuben sent this torch for review. I have not been paid for this review nor have I held back my opinions of this torch. Thanks Wuben!


The Wuben X1 came in a white box with an image of the torch on the front and specifications on the back.

Torch in use

I was amused by the idea of a rectangular torch at first. Years of using smart phones with large screens has made me accustomed to using electronic devices in this form factor.

The Wuben X1 is slightly smaller than my phone, albeit much thicker, and it fits comfortably in my medium-large sized hands.

The three emitters and the orange peel reflector produce a smooth rectangular beam.

It is comfortable to carry. The holster is really nice too!

I am tempted to buy the bike clamp that screws into the torch. This thing would be a beast on the front of my bicycle!

Build quality

The Wuben X1 is made of aluminium and this version has a white micro-arc oxidation finish. I could not feel any sharp edges.

There are two mounting holes for a bike clamp. One hole is on the head and another hole on the main tube with the cells. I measured 18.5mm to 21.5mm between the edges of the holes.

The included holster is really good. It is a perfect fit for the Wuben X1. The quality feels nice and it is easy to use.

Sometimes holsters are thrown in as an afterthought but Wuben have obviously done their research.

The holster has a strap with two buttons that make it is easier to attach to a belt or a backpack. Rather than insert a belt through the strap, the two buttons can be used to wrap the strap around a belt.

The electronic side switch has a clicky feel to it but it feels soft when retracting.

Turbo reached 41.9 C on the head after a minute. The top of the body was 36 C. And the bottom of the body was 30 C after a few minutes. Room temperature was about 17 C.

I measured the temperature with an infrared thermometer.

There is a positive and a negative terminal for each 21700 cell at the head of the torch. The cells are connected series. Two fully charged cells, 4.20V each, will provide 8.40V for the Wuben X1.

The cells are not balanced charged so it is important that matched cells are used or it could become a hazard.

The PCB with the battery charger is held in place with two screws.

LED, bezel, lens, reflector and beam

The Wuben X1 has three CREE XHP70.2 emitters and an orange peel reflector to produce a floody beam.

A glass lens with anti-reflective coating sits behind a bezel with a seal to help prevent water from getting inside.

CCT, CRI, and duv

I have taken Correlated Colour Temperature (CCT) and Colour Rendering Index (CRI, RA of R1-R8) measurements with the torch positioned one metre away from an Opple Light Master Pro III (G3).

The CCT is around 5500K. The CRI is around 67.

The Delta u, v is positive (green).

The beam has an oval shaped hot spot. You can create some interesting patterns on a wall with this torch.

User interface

The Wuben X1 has an electronic side switch.

There are four main modes: Eco, Low, Med and High. And shortcuts to: Turbo, Strobe and SOS.

State Action Result
Off Hold Low
Off Click On (mode memory)
Off Two clicks Turbo
Off Three clicks Strobe
Off Four clicks Lock-out
On Hold Cycle (Low, Med, High)
On Click Off
On Two clicks Turbo
On Three clicks Strobe
Lock-out Click Battery status indicator blinks three times
Lock-out Four clicks Low
Strobe Click On (mode memory)
Strobe Three clicks SOS
SOS Click On (mode memory)
SOS Three clicks Strobe

The torch will flash three times when entering lock-out mode.

Mode memory does not include Turbo, SOS or Strobe.


Strobe has an alternating frequency.

Programming mode

You can adjust the brightness of Eco, Low, Med and High modes as follows:

Mode Default Min (lumens) Max (lumens)
Eco 20 20 400
Low 400 400 1,000
Med 1,000 1,000 2,000
High 2,600 2,000 3,000

To set the brightness for a particular mode:

  • Click to turn the torch on.
  • Hold and release to select Low, Med or High.
  • Click and hold (2H). The brightness will ramp up or down and flash when it reaches the end.
  • Release at the desired brightness level.
  • Click and hold again to ramp in the opposite direction.

Battery status indication

The indicator LED in the middle of the switch will display the following for 5 seconds when the torch is on:

Colour Battery level
Blue Capacity ≥ 90%
Blue blinking 40% ≤ Capacity < 90%
Red 15% ≥ Capacity < 40%
Red blinking Capacity < 15%

“Red blinking” will continue while the torch is on.

Low voltage protection

I tested low voltage protection by connecting the driver of the torch to a bench power supply and then by lowering the voltage from 8.4V to 0V to emulate two 21700 Li-ion cells in series.

There is low voltage protection. The emitter turned off at 5.69V and the current dropped to 170 µA.

I noticed visible PWM (flickering) on Eco.

What I like about the UI

  • Easy to use.

What could be improved

  • It would be nice if two clicks while in Turbo always results in the torch exiting Turbo mode. I noticed that the torch remained in Turbo while peforming two clicks after coming from off, Strobe or SOS.

Batteries and charging


I unscrewed the tailcap with a 1.5 hex driver to discover two flat top Wuben branded 21700 cells with a capacity of 4800mAh each.

The tailcap had a lot of pressure due to the springs at both ends of the cells. I held the tailcap down with one hand as I removed each screw.

Wuben X1 Falcon batteries


The two 21700 cells are connected in a series. There is no balance charging. Wuben said that the included cells have been matched from the factory. They do not recommend putting in random unmatched 21700 cells.

The charging cover feels strong enough and tucks away nicely when not in use.

Wuben X1 Falcon charging

Power supply: PinePower Desktop USB-C PD
USB Meter: AVHzY CT-3 (recommended by LiquidRetro)
Room temperature: 20 C

Wuben X1 Falcon charging profile

I charged the Wuben X1 at a rate of 9V 3A after performing a runtime test. It took a little over two hours for charging to complete. The charging status indicator light went from red to blue when complete. I measured a voltage of 4.178V and 4.180V.

Charging stopped early at 3.89V and the indicator light flashed red and blue while using an AVHzY CT-3 USB Meter with the following:

  • UGREEN Mini 20W USB-C PD power adapter
  • XTAR TYPE-C45IC USB-C PD power adapter

I turned the PD switch off on the AVHzY CT-3 USB Meter and the Wuben X1 charged normally.

Power supply compatibility

I tried the following power supplies with the built-in USB-C charger:

Power supply USB Type Protocol Does it charge?
Apple 61W Power Adapter USB-C PD Yes
Google Pixel Power Adapter USB-C PD Yes
PinePower Desktop USB-C PD Yes
PinePower Desktop USB-A QC Yes

Runtime graphs

I used my own DIY lumen tube with a TSL2591 sensor and forked bmengineer’s project RuTiTe to record runtimes.

Note: Lumen measurements may be off by 10% with my DIY lumen tube.

The room temperature was approximately 17 C.

Wuben X1 Falcon runtime graph

Wuben X1 Falcon first 2 hours 10 minutes runtime graph

Wuben X1 Falcon first 10 minutes runtime graph


Here is a summary of the runtime results:

Mode User manual Runtime result Final voltage
Turbo 1min + 1.7h 2h 0min 40s 3.123V, 3.122V
High 2h 2h 5min 14s 3.086V, 3.081V
Med 5.5h 5h 43min 11s 2.984V, 2.983V
Low 14h 13h 55min 59s 3.010V, 3.005V
Eco 220h 10min+

The runtime result is the time until my lumen tube no longer detects more than 1 lumen.

I stopped recording after 10 minutes for the Eco mode because it is expected to last multiple days.

The initial lumen output and the sustained output for Turbo fell slightly short of the claim.

My runtime results were very similar to the official specifications.


I took lux measurements with a UNI-T UT383BT at 30 seconds. Eco was measured at two metres. Low, Med, High and Turbo were measured at five metres.

Mode Specs (cd) Specs (m) Candela measured (cd) Distance (m)
Eco 60 15
Low 800 56
Med 2,200 93
High 5,975 154
Turbo 23,000 303 23,300 305


I went to a local park and aimed the Wuben X1 Falcon at a tree 70 metres away while using Turbo.

Beamshots were taken using a Sony RX100M2 using 3.2", f3.2, ISO 100, 5000K WB.

The Wuben X1 is an awesome pocket sized powerhouse!

Active cooling worked well with the heatsink and fan. The temperature reached 41.9 C at the head while the body did not exceed 36 C.

There are seals everywhere to help prevent water getting in. The fan probably reduces the water resistance rating.

I love how Wuben used two flat top 21700 cells instead of a proprietary battery pack. It would be even better if the two cells were balanced charged.

It would be cool if this had a powerbank feature. I could not get it to charge my phone.

Turbo fell slightly short lumen output claim. 2,318 lm for two hours is impressive for a torch this size!


  • Excellent build quality.
  • Active cooling!
  • Holster.
  • Floody beam.
  • Built-in USB-C charging.
  • Flat top 21700 cells used.
  • Low voltage protection.


  • Batteries are not balance charged.
  • Visible PWM on Eco.
  • UI bug where I can’t exit Turbo with two clicks from off, Strobe or SOS.


The Wuben X1 Black is AU$268.28 after a 11% discount at the time of writing.

The Wuben X1 White is AU$299.93 after a 12% discount at the time of writing.

Wuben are definitely aiming for enthusiasts with this price.

It is a pretty awesome package and the sustained runtimes are impressive.
