Packaging & Accessories

Packaging here is quite nice, you have a black sleeve around a blue bifold box, with a Wuben logo in the middle. The lid is magnetic on the sides to keep everything nicely together. Inside all the accessories are in small boxes, it’s a impressive package for a pen. 

The E61 Gecko includes quite a few accessories, You get the pen body itself, a manual, micro USB Charging cable (Short), 4 different tips (Stylus, glass breaker, ballpoint pin, and inkless point). 



The light is made from aluminum and is anodized in a black or blue finish. I have the blue here but will be giving away the black version. Instead of being round like most pens, this one is more rectangular. At the pen end it has an area milled that allows the head to be pulled out of a detent and then rotated into to swap from the ink pen to one of the other available tip options. 

In the middle of the pen there is a circle that is magnetic. It’s strong enough to hold the light up in horizontal and vertical positions, and is a good balance point to allow it to spin, so kind of a fidget toy too. This allows the pen to become a mini work light too with the light bar folded out. 

The clip here is machined out of a solid piece of aluminum and is attached via the pivot mechanism the light portion is made from. It has a small place that looks like a tritium tube would fit my my 1.5mm x  6mm are too big, so possibly something smaller would fit. The clip allows for deep carry and has good retention in jeans and other pants I tried. 

The light portion is on the top back of the pen and folds out from the top. It has 270 degrees of rotation, with detents at 90 and 180. It stays in place but there is a bit of what I would in the knife world call blade play which is unfortunate. The light is allowed to shine through the opposite side of the body too.


Size and Weight

I measured the size and weight of the pen, as it came to me in the box with the glass breaker tip installed at 51.3g. Overall length when closed was 142mm, length when open is 215mm. Diameter is roughly 14mm by 10.5mm. It’s a little slimmer diameter to a Sharpy marker.


Here are some comparison photos to some other EDC Pen’s I have.


As a Light

The light here has 5 LED’s on it’s light bar all behind a diffusing piece of plastic. Instead of using RGB LED they went with individual LED’s for each color, white, red, and blue, with 2 white LED’s for more output and more even light. 

Output levels are 3 lumens, 30 lumens, and 130 lumens according to Wuben. This is powered by an internal  120mAh lithium polymer battery. Runtime follows the voltage curve of the battery pretty well, indicating this isn’t likely a regulated driver. It also doesn’t have low voltage protection so keeping the battery on the fuller side would be better for health. ON high the light got about 2 hours of runtime before it hit 10% relative output. Heat isn’t an issue here. 

The user interface is pretty simple here, single click to turn on, and long press to cycle though the 3 white modes. The light starts on Low, Med, High, and does have memory. Single press turn off at any point. To get into the flashing red, blue, red/blue mode, double press when on or from off. Single press to turn off. Memory does remember the flashing modes too. 


The light is rechargeable via onboard microUSB. When charging the switch on the outside of the light will turn red, and then blue when charged. I measured charging speed of the internal 120mAh battery at a wopping 0.10A. Total charge time was 53 min and the curve was flat. 


As a Pen

The Wuben E61 Gecko is a light duty pen in my opinion. That’s mainly due to the small size of the cartridge 22.5mm in overall length. This doesn’t leave much room for ink about 9mm of visible ink in my cartridges. The good news is here that the cartridge is a pretty standard design ballpoint design, so you can find things that will fit in your average Bic pen, or hotel pen, but to use these you need to first write 90% of the pen so you can cut the empty tube and it will fit. In the hand it’s ok, it’s not the worlds most comfortable pen, but for short uses it does the job just fine. I like the diameter here better then say the Olight Open which I will review in the next few weeks. 

Don’t forget the other accessories on the opposite side of the pen too, you have a metal scribe tip, a ceramic ball for a glass breaker, and the stylist tip. These may end up being a little more practical depending on your use case and the ink pen may become a secondary for you.



  • Non proprietary ink cartridge but it will require a bit of customization.
  • The light bar function here is more useful then your average pen light, especially with the side magnet making it an actual usable light.



  • It would be nice to see USB-C here.
  • Very small ink cartridges.
  • Pivot points seem to use a proprietary head design.



I like that this isn’t a tactical first pen light, It’s pretty usable for everyday, although with the very small ink cartridges I wouldn’t want to do tons of writing with it or you will be swapping in new cartridges frequently. So like a lot of pen light designs it makes compromises on both the pen and the light side. The weight here is nicely balanced so that when using it, it doesn’t have a lot of weight at the back end which is good. 

As a light it has a fairly even beam in white mode and is fairly decently diffused. It’s L,M,H which is good, and double click to get into the colored strobe mode which is good. I just kind of question what you would practically use the red, blue, red/blue strobing modes for practically, maybe to get someone’s attention on the side of the highway?
