Wuben E10

Wuben E10 Flashlight review (1200 Lumens)


Wuben calls the Wuben E10 a multifunction flashlight. Besides the battery configuration and its price, what else could be so special about the E10?

It has the shape of a tactical flashlight, but it isn't! It's a EDC flashlight with a simple UI and at an affordable price.

And what about the Osram P9 LED? Is it cool white, warm white, neutral? And does it really produce 1200 Lumens in Turbo and 1 lumen on Low? Let's find out

What you'll get:

  • Wuben E10
  • Box
  • Spare O-rings
  • Pocket clip (already attached)

Handling of the light and knurling

The Wuben E10 has pretty good dimensions for an all-round flashlight. Great for around the house, great for in the car, great for in your backpack. The E10 only has knurling on 2 parts of the flashlight, namely, on the tailcap and on the body. Both are pretty minimalistic, and don't necessarily help with grip.

Most of the body has no knurling, and fortunately there is some knurling on the tailcap, since it's pretty hard to unscrew. If this didn't have any knurling, it would have been pretty difficult to open!

Pocket clip
The pocket clip was already attached when I received the light. It's pretty stiff, and seems like make of ok quality. I pulled it a little to strongly, and broke it! ouch.

Please, only use the pocket clip for what it is made for, and don't start pulling it as hard as you can... it will break 😉


No problem!

Build Quality, anodization

Besides breaking the pocketclip I couldn't find anything wrong with the build quality. It does however look right on the money. The build quality doesn't look very cheap, nor does it look high-end. So you definitely get what you pay for. Anodization seems to be fine as well!

Wuben added glue (or thread locker) to the head parts, so it is impossible to open by hand. You need some tools or heat to open this one up.

Threads and O-rings

The O-ring near the tailcap is pretty thick and stiff. Not sure if this is how it is supposed to be, but my other Wuben flashlight had the same. It was very hard to remove. I guess this helps with the waterproofness! It had enough lube, and are square cut.

LEDs, Lens, Bezel and Reflector

Although the manual nor the manufacturer's website mentions anything about tint/color, from my own observations this LED might be an NW. Wuben gives at least the name of the LED: Osram P9.

The LED is well centered in the plastic, smooth reflector. The bezel is glued, so I can't really look inside.

The beam profile is good, without any strange artifacts. There is definitely a defined hotspot!


For an 18650 flashlight, the Wuben E10 is a little on the large side, but not too large. It actually has a pleasant size for what it's worth.

  • Length : 125.3mm / 4.93"
  • Width tailcap: 25.5mm / 0.99"


  • Weight empty: 76.6gr / 2.7 oz.
  • Weith incl. battery: 127gr / 4.48 oz.

User Interface:

The Wuben e10 has a very simple User Interface. You don't need to learn anything special, unlike many other flashlights on the market with hidden modes.  It's a simple click for on, and taps for mode changing.
It uses a reverse-clicky switch.

Low - Med - High -  Turbo

The jump from Low to Medium is a little bit on the big side. I would have preferred a slightly smaller jump to about 30-50 lumens.

From OFF:

  • Single click: ON (mode memory)

From ON:

  • Single click: Off
  • Half clicks (taps): chaning mode
  • 2 Quick taps: Strobe

Strobe mode:

A quick double tap brings you into strobe mode. I prefer having a double tap for Turbo, since most other flashlight firmwares use it.

Mode memory: 

The Wuben E10 is a little strange here. At first it looked like it works with Last Mode Memory. Which means that it will remember the last used mode. So if you re-activate the light, it will start from the mode you used last. But in reality it will only kick in after about 8 seconds.
If you turn it off and reactive it within 7 seconds, it will go to the next mode (Next Mode Memory). But if you wait long enough, it will actually just go back to last used mode.

Momentary on:

Nope! It's also not a real tactical flashlight, but a general/EDC flashlight.

Batteries and charging:

The Wuben E10 uses normal rechargeable 18650 lithium batteries. You can either use protected or unprotected batteries since it uses springs on both sides.


Wuben claims it to have 1200 Lumens on Turbo, and 1 Lumen on Low. Both numbers are quite interesting for this type of light. I tested the Wuben E10 in my intergrated sphere which was calibrated using a Convoy S2+ at 137 lumens.

Wuben E10 Mode My measurement Mfg
Moon 0.97 Lumen 1
Low 113 Lumens 100
Med 452 Lumens 300
High 1119 Lumens 1200

This means that the manufacturer's claims aren't exaggerated! Low is almost on par, and High is just a bit lower. This makes it an interesting flashlight for sure! The measurements were taking using a Samsung 30Q 18650 unprotected, flat top battery,


The runtime was taken using a pink Samsung 30Q 18650 High Amp battery, in Turbo.

Within 1.5 minutes the output dropped to about 57% (roughly 650 Lumens) which continued for about 95 minutes. From this point is starts to slowly drop, and at 100 minutes it is 45% (510 Lumens) and at 152 minutes I stopped the test. At this point it produced only 36 lumens. (3%)

Low voltage protection:

The E10 starts to flicker/blink at a certain battery level, you can see the diagonal line near the 90 minute mark, which indicates one of these blinks. The blinks are very short, so the app didn't detect them all, but they can be seen more then a handful of times.
The battery was at 2.64 Volts when I took it out. This is not really recommended, so better remove the battery when the E10 starts blinking, and output decreases.


  • I couldn't detect it by eye, and that is the most important! PWM is fine as long as it's not at a point that it starts bothering you.


  • Throw measured at 5 meters, indoors, with a Samsung 30Q High Amp 18650 unprotected battery: 16500 cd.

The manufacturer claimed 11556 cd, so it seems that it performs better than expected.


  • This time I did some white wall beamshots to compare tint and to show the beam. In the pictures below you can see that the E10 has a pretty distinct hotspot in the middle. This is because of the smooth reflector. From left to right: Lumintop FW3A (XP-L Hi 3D LED), Reylight Krystal (Nichia Hi Cri) and Wuben E10 (Osram P9). The beam of the E10 is a little on the cool side, but in the beamshots below you can see it's not too cool white!

Overall conclusion


  1. Simple UI
  2. Affordable
  3. Great size
  4. Works with protected and unprotected batteries, flat top and button tops


  1. Turbo activated by double click
  2. The output difference between Low and Medium is a bit big.
  3. Nothing very exciting features besides the Osram P9 LED

Overall Rating: good

The Wuben E10 is an average flashlight with average specs. The only difference that stands out is the Osram E9 LED. A neutral white LED with a nice tint! The UI with a quick tap for Strobe is not great since most other flashlights have a double tap to Turbo, instead of Strobe.
