Review intro:

We’ve seen Wuben being mentioned more and more in the flashlight community, and for good reason. They are building some very interesting lighting products, including flashlights and headlamps. Their X series have been pretty popular.

This time, we are looking at the E7, a right-angle flashlight for less than $40. It can also be used as a headlamp, as long as you buy the optional headband for it.

Let’s see if it’s worth the price!

What’s in the package

I quite enjoy Wuben’s packaging, which is pretty functional as well as pleasing to look at. Inside the box, you can find the following:

  • Wuben E7
  • 18350 battery (loaded inside the flashlight)
  • USB-C charging cable
  • Lanyard
  • 2 O-rings
  • Manual

Wuben also sent me the optional headband (Wuben P1) as well as the 18650 extension tube (E7 extension tube) and the Wuben Inductor (AP40) which is used to control the E7 by hand movement.

Remove the battery insulator from the tailcap before your first use!

Flashlight in use, Build Quality, and Warranty

Somehow Wuben seems to focus their attention on unique designs, that all started to become popular with the X0, X1, X3 etc.

This time, we are looking at the E7, but again with a similar rectangular design, reminding me of the Wuben X0. That, except for the dual LED setup.

Its design, and the fact that there is a magnet in the tailcap, means that you won’t easily loose it. It doesn’t roll of a table, and it can stick pretty well to metal. The same tailcap is also the spot where you can attach a lanyard. Unfortunately, I had a really hard time getting the lanyard through the hole.

The switch design is definitely different from the X0, which basically had a metal flap on top, to manipulate the switch underneath. This time, its just a normal switch, sitting flat with its body, but protected by 2 shrouds. This reduces the risk of accidental activation, but I still recommend using the lockout feature (4 clicks from off) for your own safety.

The pocket clip is also totally different, and more in line to what we are used to with other flashlight brands. It’s not as stiff as on the X0, and but still enough for normal use. The other big difference is the removable battery in the E7 instead of the on built-in on the X0.

Wuben’s optional P1 headband is setup so the pocket clip of the E7 fits right into place, securing it into the headband well. You’d have to press a little lever to remove the E7 from the headband again.

The headband has a secondary strap that goes over your head to make the E7 sit even more stable. Both straps are adjustable to fit your size.

Wuben’s 18650 extension tube isn’t the best. First of all, it doesn’t line up perfectly with the body, so the flats of the body and extender are not lining up. And therefore, if you want to attach the E7 with the extender to the headstrap, you have to slightly unscrew the extender to line up.. Once it’s lined up, you can tighten it again.

Also, the extender doesn’t screw very nicely.. the first bit goes pretty smooth, but the last bit is a bit rough. Keep that in mind. It’s nice to have an extender, but it’s not as practical.

Wuben Inductor (hand movement sensor)

The other interesting optional accessory is the Wuben Inductor, which is basically a motion sensor. For an extra $10, you get the headband and this sensor included. I’m not sure if I would ever use it, but I quite like thie idea. It needs some practice to get it to work consistent, because when it’s located on your head, it can be a bit difficult to locate it without seeing it.

You can either use the USB-C cable that is included with the Inductor, or the USB-C cable that is included with E7. Both work, to connect the Inductor to the USB port of the E7.

There is a blue light indicating that the sensor is active. You can control it by hand movements within about 5cm/2inch from the sensor. And here are the methods to control:

  1. Single hand movement equals a single click (turns the light on/off)
  2. Double hand movement equals a double click (Turbo mode)
  3. Three hand movements equals 3 clicks (strobe SOS)
  4. Four hand movements equals 4 clicks (lockout)
  5. Keep your hand in front of the sensor for a longer period equals Long-press (runs through the modes from low to high)

This is pretty cool, especially since it’s an optional accessory. It’s not built in, but if you want to use it, you can. It doesn’t work on the X0 or X2.. Yup, I tried that.

With all these features I can see it being used in many scenarios, including walking, EDC, jogging, camping, working.

LED, Lens, Bezel, Beam, and Reflector

I like the fact that Wuben shares the LEDs they are using in their flashlights. This time, they are using the Osram P9 LEDs, and you get the choice between 6500K and 5000K. This means you can choose between cold white, and pretty neutral white. Some people would regard 5000K as cold, but in my opinion that’s neutral. I used to think that 4000K is neutral, but 5000K is probably exactly neutral, because shining 4000K on white paper makes it look yellow / warm.

This time however, you don’t get high CRI when you choose the 5000K option. Instead you just get standard CRI.

The LEDs sit inside a dual TIR optic, which are frosted in the middle, producing a beautiful smooth transition from hotspot to spill. Even though there are 2 LEDs, you don’t see 2 hotspot, since both of them blend in really well. I quite enjoy that.

At this point in time, I rather have standard CRI, cold white LEDs with a smooth beam, and close to BBL, than High CRI, negative DUV for EDC use. To me, a smooth beam has a higher priority for EDC than high CRI.

The bezel seems to be removable, but there might be some loctite inside.

Let’s have a look at the quality of the beam.

Spectral measurements:  

I used a Sekonic C800 spectrometer to measure the flashlight at 5 meters distance for Turbo mode, and about 2 meters for Medium modes.

Wuben E7 Charging and batteries

The Wuben E7 stands out from the X0 X2 or X3 because of the removable battery. You can simply unscrew the tailcap to access the battery. However, the tailcap is thin, and doesn’t have enough surface to get a good grip. I would have like Wuben to make this tailcap perhaps 1-2mm thicker, for a better grip.

You don’t really need to remove the battery, because it can be charged inside.

The included battery is labeled as Wuben ABJ1100C, and it’s an 18350 battery with a claimed capacity of 1100mAh. You can also use flat top and button top 18350s, because there are springs on both terminals, positive and negative. However, you can’t really use long 18350s with charging ports.. even they will let the light turn on, you can’t screw down the tailcap completely.

You can take the battery out and charge it in a normal charger, while you continue running the E7, but if you charge the battery inside, you can count on the following charge times.

I tested total charging time, 3 times, and I got 1h 21min, 1h 29min, and 1h 29 min respectively. This basically is roughly 1h 25minutes on average. You can use the included USB-C cable, but any USB type C would work.

During charging, a red light is visible, and it’s charging at 5V and 1A.

Lumen measurements:

How Lumens are Measured: Understanding ANSI FL1 Standards How Lumens are Measured: Understanding ANSI FL1 Standards: The ANSI FL1 standards specify that output in lumens should be measured 30 seconds after turning on, as this is the standardized time for measuring brightness according to the industry standard. This is why we focus on this part in our measurements. The ANSI FL1 standards require an ambient temperature of 22 ± 3°C. We record the ambient the ambient temperature to identify potential reasons for any observed discrepancies.

The output measurements in this review are based on my homemade integrating spheres, each equipped with an Extech SDL400 Lux Meter. For consistency and accuracy, a calibration light (Convoy S2+ with 249lm and a Convoy S2+ with 261lm) is measured before each set of lumen measurements.
One of the lux meters uses an ND camera filter for high-output lights to prevent the lux meter from maxing out. This is either the Kenko PRO1D ND16 for up to about 80,000 lumens or the Gobe ND32 for anything above.

All of my readings were taken from a fully-charged Wuben 1100mAh battery.

The measurements were taken manually at turn on and 30 seconds. The 10-minute numbers are taken from the runtime graph.

Unfortunately, I couldn’t reach the claimed outputs. And interestingly, the NW version performed better than the CW version.

Ambient temperature during testing:

Parasitic drain:

  • 60 µA (The 1100 mAh battery would take 18333 hours to discharge completely, which is more than 2 years.
    • Explanation on milliamps (mA): 1A is 1,000mA
    • Microamps (µA): 1mA is 1,000µA

Wuben E7 Battery life and runtime

How Runtimes are Measured: Understanding ANSI FL1 Standards About ANSI FL1 runtime standards: The runtime is measured until the light drops to 10% of its initial output (30 seconds after turning 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.

Runtime tests were conducted in my 50cm homemade integrating sphere, paired with the Extech SDL400 data logging Lux Meter. Temperatures from the moment the runtime test started.

I only tested the 6500K version, excluding Low mode, and here are the runtimes.

Wuben E7 Peak beam intensity and beam distance measurements

About Peak beam intensity: Understanding ANSI FL1 Standards About peak beam intensity The calculated value of distance in meters at which the flashlight produces a light intensity of 0.25 lux. (0.25 lux is about the brightness of a full moon shining on an object). This means that the intensity has decreased so much, it becomes difficult to see darker objects, or objects that don’t reflect light. The columns ‘Meters’ and ‘Yards’ use rounded numbers.

Measurements were taken indoors with a Hagner E4-X Lux Meter. The measurements were taken 30 seconds after turn on.

Beamshots

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

The shed is about 65 meters / 71 yards away, and the reflective fence is about 200 meters.

Explore and compare the beamshots from the following flashlights:

  • Wuben E7 (cw)
  • Wuben E7 (nw)
  • Wuben X2
  • Wuben X3
  • Olight Arkfeld

Please note that the following beamshots are mainly intended to showcase the beam pattern and beam quality, rather than overall performance. These images are typically taken directly after activation, and in different seasons or weather conditions, and therefore do not fully represent its overall performance. For accurate performance metrics, such as output, beam distance, and runtimes, you need to look at the performance section of this review.

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

4 stars: ★★★★

While our star rating provides a reliable indicator, we encourage you to read the full review to make an informed decision based on your own needs and preferences.

I think it’s fair to compare it to the Wuben X0, its smaller sibling. The new E7 will have a few advantages, namely the following: higher output, removable battery without needing tools, nicer pocket clip, optional sensor, and an optional extension tube for 18650 batteries.

But you don’t have the option to choose High CRI, Moon mode, direct access to the lowest mode, or program the different outputs. So both lights have their pros and cons.

All in all, this is quite an interesting new offering from Wuben, with okay performance but rather short runtime in Med, High and Turbo mode.
