Introduction:

Wuben is still a relatively unfamiliar brand outside the flashlight community. But they are pretty innovative, including the recently launched (and reviewed) Wuben A1, which is one of the most expensive lights we ever reviewed. And this is yet another unique light.

Flashlights are usually cylindrical, that doesn’t mean they have always been, or always will be. The one I’m reviewing isn’t cylindrical either, it’s rectangular with 3 LEDs sitting in a row.

These aren’t just your average CREE XML LEDs with a couple of hundred lumens. They are 3*CREE XHP70.2’s which promises a high output, and……. lots of heat. And that’s what Wuben tried to tackle with something special. They added a very quiet fan, that blows air through the body (where you can see some bare aluminum heatsinking fins). Yes, you can look through the flashlight from the side.

Just when I finished this review, the flashlight was announced.

Package quality.

Mine came in a generic plastic box, with the following:

  • The flashlight: Wuben X-1
  • Lanyard
  • USB-C to USB-C charging cord

This is a prototype product without any branding, images, or text. I expect you will receive a typical Wuben box, with a nice number of accessories, and of course, the branding printed on the body.

Mine also received with a broken bead. I’m not sure if that was supposed to be inside.

Flashlight in use

A cylindrical flashlight gives a natural grip with your hand, especially when the diameter feels just right. The X-1 doesn’t have this kind of feeling because of its unusual design. That doesn’t mean it’s a bad design, just …. different.

So let’s start with the most obvious benefit: it won’t roll off the table. And secondly, you can make its tail-stand quite stable and fit in your pockets easier than a 2*21700 cylindrical light.

There is no knurling like you find on a typical flashlight, so it can feel a bit slippery. But the cutouts, corners, and grooves on the battery tube help with a bit of grippiness. And you can always attach the lanyard in case you prefer carrying it that way.

The X-1 uses a single e-switch, that sits in the top middle of the light. Basically about the spot you would rest your thumb.

The use cases for this kind of light could be multiple. I wouldn’t be surprised if some people would carry it as an EDC for work, but generally speaking, it’s a bit too big for everyday carry. I’d probably use it in a car, or just on an occasional walk. The output (up to High) is maintained pretty well, so you wouldn’t burn your fingers while walking the dog and have plenty of runtime.

Build Quality, and Warranty

Oh, yeah, this one looks pretty robust. The only thing I would worry about is the fan getting clogged with dust or accidentally activating the light while carrying.

The anodization is matte black and covers the whole light. Since I have no manual or website with specifications, I wouldn’t be able to tell of what kind of aluminum it’s made, or what type of anodization is used.

Once the light is available, I guess it will be available in several different colors, just like the X-0.

Here’s what Wuben mentions about its warranty on its website:

  • 30 days money-back guarantee: Within 30 days from the date of purchase, if the product has quality problems, customers can request full refund.
  • 30 days replacement: Within 30 days from the date of purchase, if the product has quality problems, customers can request free replacement.
  • 1 year warranty: Within 1 year from the date of purchase, if the product has quality problems, WUBEN will offer free repair.
  • Battery warranty: WUBEN offers a 1-year warranty for the rechargeable batteries but other included accessories are not covered by the warranty.
  • 5 Years product warranty: Within 5 years from the date of purchase, if the product(for battery-removable flashlights, accessories excluded) has quality problems, WUBEN will offer free repair for WUBEN registered customers(Support-Product registration).
  • Lifetime maintenance: From the date of purchase, if the product has problem after 1 year, WUBEN will offer paid repair for WUBEN registered customers.

So, it’s better to register your light, so you can get the best possible warranty.

LED, Lens, Bezel, Beam, and Reflector

I can only share what I can observe and measure. I don’t know what Wuben will mention about the LEDs when this flashlight comes available, or whether there will be more LED options, but the one I received has 3*CREE XHP70.2’s. That means a lot of output, and a lot of heat if used in Turbo mode, and likely in high mode.

The LEDs are sitting in a row, with shallow orange-peel reflectors. And that’s a smart choice because the beams of XHP70.2 can show quite a bit of tint shifts, from purple to green. And with an orange peel reflector, you’ll reduce that shift a bit, albeit still visible.

There is a hotspot and a great amount of spill, but the transition from hotspot to spill is very smooth. The most obvious thing you can see is the difference in tint at the hotspot and spill. The hotspot is more ‘greenish’ and the spill more ‘purplish’. But the measurements with the Opple Light Master III (pro) weren’t too bad.

I got the following, measured at a distance of 1 meter, and a few seconds after turn on.

Low mode:

  • CCT: 5353K
  • CRI (Ra): 67.2
  • DUV: 0.0103

Turbo mode:

  • CCT: 5595
  • CRI (Ra): 67.8
  • DUV: 0.0071

Keep in mind that these measurements are not 100% perfect, and can differ a few percentages. The DUV changed 30% between Turbo and Low, but differs also, depending on the time you measure it after the light is turned on. So you can’t give just 1 DUV number, because it’s so dependent on many variables.

  • Ultra low, Low, Medium, High, Turbo
  • Strobe, SOS

From OFF:

  • Single-click: to last used mode; mode memory, except blinkies and Turbo
  • Double click: Turbo
  • Triple-click: Strobe
  • Press and hold: Lowest output mode (I just call this Ultra Low for the moment… but it’s not very low)

From ON:

  • Single-click: light turns off
  • Double click: Turbo
  • Triple-click: Strobe
  • Press and hold: Run from ultra low to high: UL-L-M-H-UL-L-etc

Shortcuts:

  • To Turbo: double click from on/off
  • To ultra low: long-press
  • To Strobe: 3 clicks from on/off

Mode memory:

  • Yes, but not Turbo, or either of the 2 blinkies

Blinky modes menu:

  • Yes, you can enter strobe with a triple click.. and repeat to toggle between Strobe and SOS

Firmware / UI Conclusion:

It’s a very nice UI, with the usual, well known, shortcuts to the Lowest mode, Turbo mode and even Strobe.

Batteries & Charging

NOTE: This flashlight isn’t supposed to be opened, and you are likely to lose any warranty by doing so.

There are 2*21700 batteries built-in, which are removable without too much trouble if you have to. Just make sure you insert them the correct way.

A USB-C to USB-C charging is included, and a red indicator LED shows the battery is charging. When it turns blue, the batteries are fully charged.

Charging goes automatically at 9V and 2A, so the batteries are fully charged within 2 hours!

I normally use a USB-tester to see the charge current. But just before it finished charging it kept switching the charging light from red to blue constantly. I used a USB-C power adapter, and it looked like it wanted to discharge the flashlight batteries and charge the power adapter… strange. At 1 point it discharged the batteries, because when I noticed this strange behavior and swapped to a normal USB-A to USB-C cable it charged again for a while, at 9V and 2A.

I didn’t have this problem with a normal USB-A to USB-C cable.

After all the testing, I tried to charge my phone with the included cable, but nothing happened. I believe that there is a power bank feature, but it didn’t work (anymore) on mine.

Performance test

Lumen measurements:

All output numbers are relative to my homemade Integrating Sphere. It is set up with an Extech SDL400 Lux Meter for measurements including a Kenko PRO1D ND-16 filter. The base measurement is done with a Convoy S2+ that has been tested at 255 lumens.

All of my readings were taken with fully charged batteries.

Moon18.7718.77
Low399400397
Med1,0121,010996
High2,6082,5822,504
Turbo10,103 lm9,566 lm2,461 lm

Runtime: Battery life

The runtime test was done with the 50cm integrating sphere, including the Kenko Pro1D ND-16 filter and Extech SDL400 data logging Lux Meter.

ModeSpecified runtimeMeasured runtime (ANSI FL1)Time till shut off
Moon?
Low?13h59min13h59min
Med?5h44min5h44min
High?2h01min2h01min
Turbo*?1h57min1h57min

ANSI FL1 standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turn on). This does not mean that the flashlight is not usable anymore. The last column shows how long the light actually works till it shuts off. If there is a + symbol, it means that the test was stopped at that particular point, but the light was actually still running. This happens on certain occasions, with certain drivers, firmware, or batteries.

Throw Measurement: Peak beam intensity and beam distance

Measurements were taken indoors at 5 meters with a Hagner E4-X Lux Meter. Lux were measured and converted to Candela. Meters and Yards

Extra info: Peak beam distance according to ANSI FL1 standards: The calculated value of distance in meters at which the flashlight produce a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object).

Beamshots

For the following beamshots I used a Canon EOS 5D Mk2 and a 50mm lens. manual settings: ISO1600, 1/4sec , F4, 5000K

The shed is about 65 meters / 71 yards away. 

Disclaimer: This flashlight was sent to me for review at no cost by Wuben. I have not been paid to review, nor have I been holding back on problems or defects.

Final Verdict

Pros

  1. 10,000 lumens at turn on, and 9,500 at 30 second
  2. Pretty high sustained output for its size!!!
  3. Built-in fan to keep the temperatures down and maintain a high output
  4. Fast charging at 9V and 2A
  5. Likely available in different colors
  6. No PWM

Cons

  1. Purplish and greenish tint shift because of the XHP70.2 LEDs
  2. A little unusual design, and a little heavy

Explanation on star ratings:

1: Avoid: my phone flashlight would be a better choice – 2: Poor: significant defect or issues; almost unusable – 3: Average: some defects or issues; but still usable 4: Good: recommended (minor issues) – 5: Great: highly recommended
