Package and Manual

It’ll be better when Wuben provides the PDF as they usually do. Until then, here’s my scan.

Build Quality and Disassembly

The Wuben G5 Yellow EDC keychain flashlight has an interesting design. It’s like a light we’ve seen before – also by Wuben. The Wuben X2 Pro. But while they’re similar, I like the G5 just as much as I disliked the X2 Pro. The G5 is very fun!

There’s nothing I could disassemble on it, though. The battery is in accessible.

This G5 is internally the same as the other G5 I tested a while back. I haven’t performed any additional testing on this yellow version, and the original data is presented here. Basically, if you like yellow, then you’ll need this light!

Size and Comps

Dimensions: 3.7cm × 1.5cm × 6.2cm
Weight: 52g

Below is the light in my regular-sized hand.

Here’s the test light with the venerable Convoy S2+. This one is brass!

In the photo above, you may note that the SRM (standard reference material) flashlight for comparison has changed! I used a TorchLAB BOSS 35 for ages. Now, what you can see as the 18350 SRM is the Hanko Machine Works Trident. While I have not reviewed or tested the Gunner Grip version seen here, I have tested a Hanko Machine Works Trident Total Tesseract in brass. I love the Trident, and it’s a striking contrast next to the inexpensive Convoy S2+, which also makes a great standard reference material.

Retention and Carry

A lanyard is included with the Wuben G5 Yellow EDC keychain flashlight. It attaches through the hole you can just barely see at the far right, below.

There’s also a magnet at the bottom of the Wuben G5 Yellow EDC keychain flashlight. It’s decently strong. Not super strong, though.

A pocket clip is also included and built in. I didn’t capture it here, but the clip can be pushed forward (outward) from its attachment point and pivoted. So you can carry the Wuben G5 Yellow EDC keychain flashlight flat against a belt, for example, or use it on the bill of a cap.

Power and Runtime

I can’t see where Wuben makes any claim about the capacity of the built-in LiPO. The battery is not removable or replaceable.

There are two specific modes with the white emitter. The lowest output is around 2 lumens, and the highest is around 400. Between those two are variable and non-specific (so I didn’t test any runtimes on those modes).

Here’s a runtime on the highest level. Highest when the wheel scrolls and highest by double clicking are the same.

Charging

With the built-in battery, you expect charging. And the Wuben G5 Yellow EDC keychain flashlight has that. There’s a USB-C charging port just under this fidget switch. The switch also has a locked position.

A USB to USB-C charging cable is included.

Charging looks great and takes only around 1.5 hours.

During charging, the indicator is red. When charging is complete, this indicator turns blue.

Pulse Width Modulation

All of the modes use PWM. Below, left is the lowest, then the higher white output. One of the RGB options is on the far right.

Here you can see a “baseline” – a chart with almost no light hitting the sensor.

Then there’s the Ultrafire WF-602C flashlight, which has some of the worst PWM I’ve seen. It’s so bad that I used a post about it to explain PWM! Here are multiple timescales (10ms, 5ms, 2ms, 1ms, 0.5ms, 0.2ms) to make comparing this “worst” PWM light to the test light easier. That post also explains why I didn’t test the WF-602C at the usual 50us scale.

User Interface and Operation

There’s one e-switch for operating the Wuben G5 Yellow EDC keychain flashlight. Before you get to that, though, you’ll need the slider switch in the “light” mode. It can be locked (all the way back), LED (middle), or charging (all the way forward).

The switch is nice, and the action is very low. Placement is just a bit awkward, especially if you plan to use the roller wheel to select modes with the same finger, too.

Here’s a user interface table! Of course, you’ll need the slider switch in the “LED” position for any LED output change!

State	Action	Result
Off	Click	On – memory
On	Click	Off
On	Hold	Switch between White and RGB (with level memory)
On	Double click	White: Turbo RGB: Blinking of the active color
On	Dial rotary control	White: Increases or decreases output RGB: Advances through RGB color options
Turbo	Double click	Previous mode
RGB Beacon	Dial rotary control	Advances through RGB color options in beacon output
RGB selected but off	Double click	Red/Blue flash
Red/Blue flash	Double click	Red/Green flash
Red/Green flash	Double click	Red/Yellow flash
RGB Beacon	Double click	Previous mode (of steady RGB)

LED and Beam

Wuben doesn’t say what emitters are used here. The bigger opening TIR is the main white LED, and the smaller opening is the RGB option.

Here’s a bit of RGB magic from the black version.

LED Color Report (CRI and CCT)

Despite not knowing what emitter is used here, the CCT and CRI are no surprise – Cool white and low CRI.

CCT (Correlated Color Temperature) refers to the measurement of the color appearance of light, expressed in Kelvins (K), which indicates whether the light is warm (yellowish) or cool (bluish). A lower CCT (below 3000K) is considered warm light, while a higher CCT (above 5000K) gives cooler, bluish light.

CRI (Color Rendering Index) is a measure of how accurately a light source renders colors in comparison to natural sunlight. Scored on a scale from 0 to 100, higher CRI values indicate that colors appear more true to life and vibrant, similar to how they would look under the sun.

Beamshots

These beamshots always have the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure. These photos are taken at floor level, and the beam hits the ceiling around 9 feet away.

Tint vs BLF-348 (KillzoneFlashlights.com 219b version) (affiliate link)

I keep the test flashlight on the left and the BLF-348 reference flashlight on the right. These photos are taken around 18 inches from the door.

I compare everything to the KillzoneFlashlights.com 219b BLF-348 because it’s inexpensive and has the best tint!

Summary and Conclusion

I like how small the Wuben G5 Yellow EDC keychain flashlight is, and it’s quite versatile with all these options. The RGB is neat and fun. White options are interesting, but I’d rather have five or so specific modes. I understand that people like ramping, though, so I’ll give that one a pass. For $20, though, this is a very fun toy!

^ Measurement disclaimer:  Testing flashlights is my hobby. I use hobbyist-level equipment for testing, including some I made myself. Try not to get buried in the details of manufacturer specifications versus measurements recorded here; A certain amount of difference (say, 10 or 15%) is perfectly reasonable.

What I like

• Low cost!
• Neat use of RGB
• Nice slider cover for USB-C port (and fidgeting)
• Interesting pocket clip design/option
• Yellow body is bright and fun!

What I don’t like

• The rotating LED head seems a bit useless
• Only rotary control for levels – no discrete levels
• Cool white
• Low CRI
