Wuben E2 Microlight Review: A Tiny $20 EDC Light That Does More Than You Expect

Introduction

Micro lights are easy to dismiss as novelties, but the Wuben E2 makes a good case for keeping one in a pocket, bag, or kit. It is a USB-C rechargeable, 150-lumen emergency and EDC light that costs about $20 and comes in two finishes: gradient black and gradient red.

What sets it apart from simply using a phone light is the combination of a magnet, a metal clip, side lighting with multiple flash modes, and runtimes that make low-mode use genuinely practical. It also weighs just 10.7 g, so carrying it is barely a consideration.

Who This Microlight Is For

The E2 fits a specific but common need: an always-with-you backup light for situations where darkness arrives unexpectedly. The type of moment where it is suddenly dark an hour earlier than it was last week, or you are out cycling and daylight disappears faster than planned.

Because the body is plastic rather than machined aluminum, it does not roll away when set down, a small but real advantage over cylindrical metal lights. It works as an emergency light, a neck-worn light, a tent or tabletop ambient light, and a night light for emergencies, all in one tiny package.

Main Strengths

The headline output is 150 lumens in the forward white light, which holds for about a minute before throttling down. At 100 lumens you get roughly 30 minutes of runtime, enough to carefully jog through a forest, and 50 lumens is bright enough to light up a walking path. The 5-lumen low mode is ideal for close-up work in a fully dark environment.

Runtime at the bottom end is where it gets interesting: the 5-lumen mode delivers up to seven hours of continuous light. For emergency use or as a night light, that is a serious amount of endurance from something this small.

Carry Options: Ring, Clip, and Magnet

Wuben includes a split ring for attaching keys, a metal clip that snaps directly onto the body, and a small beaded chain that turns the E2 into a wearable neck light. The accessories are interchangeable, so you can move between pocket carry, keychain carry, and neck carry without buying anything extra.

There is also a built-in magnet, and it holds well on metal surfaces. Sticking the light to a fridge, a car body, or a metal shelf frees up both hands, which is exactly what you want from a light this size.

Side Lighting and Flash Modes

A double click switches from the forward beam to side lighting, which adjusts between 10 and 80 lumens. That side light is the most versatile part of the E2: it works well as ambient light, hangs comfortably in a tent, and has real small-area tabletop lighting potential.

The flash modes include breathing, standard flashing, and a red-and-blue alternating flash. And once the light has been lit, the body itself glows a soft green after you turn it off, which makes it easy to find in the dark.

Things to Consider Before Buying

The main trade-off is output. This is a 150-lumen light, and the top setting lasts only about a minute before settling at 100 lumens with a 30-minute runtime. If you need sustained high output or long throw, a larger light is the better tool.

It is also a deliberately simple product. There is no fancy user interface or adjustable beam, just sensible brightness steps, side lighting, and flash modes. If your idea of an EDC light involves more power or more features, this may feel limited. If you want something cheap, light, and always ready, it is hard to argue with.

Runtime and Brightness Modes

Recapping the modes in order: 5 lumens for up to seven hours, 50 lumens for walking paths, 100 lumens for about 30 minutes, and 150 lumens for roughly a minute before throttling down. Side lighting spans 10 to 80 lumens and covers ambient use nicely.

The comparison against two other small lights running 14 hours at 5 lumens shows how competitive this segment has become, and it is encouraging to see Wuben exploring this micro light space with something this affordable.

Buying Advice

At around $20, the Wuben E2 is an easy, low-risk addition to an emergency kit, a cycling bag, or a keychain. Choose gradient red or gradient black based purely on taste; the hardware is the same.

Buy it if you want a featherweight backup light with a magnet, a clip, usable side lighting, and long low-mode runtime. Skip it if your main need is a powerful primary flashlight. For getting through the darker months, though, it does exactly what it promises.

Conclusion

The Wuben E2 proves that a $20 microlight can be genuinely useful rather than a gimmick. With 150 lumens on tap, seven hours at 5 lumens, a magnet, a clip, and thoughtful side lighting, it covers an impressive range of small everyday lighting jobs. For anyone building out an EDC setup or an emergency kit, it is an easy recommendation.
