Wuben G5 Review: A Cool Idea That Makes You Work Too Hard to Use It

I want to start with a question I keep asking myself the longer I spend in this hobby: how many ways can you really design a flashlight? At some point you have a body, a head, a switch, and a light source. The core problem has been solved for a hundred years.

So why does every manufacturer feel compelled to reinvent the geometry, relocate the button, add a slider mechanism, and then ship it with a pocket clip that doesn’t actually work?

The Wuben G5 is a good example of what I mean. On paper, it looks genuinely interesting. In practice, it made me fumble around in the dark more than any flashlight probably should.

Let me back up and give you the full picture. I review a lot of flashlights! See all my flashlight reviews here.

Why I Bought the Wuben G5

I’ve been working on a piece about the best flat EDC flashlights on the market, and honestly, I don’t fully understand the appeal of the form factor to begin with.

A cylinder has worked for a hundred years. People insist on reinventing that shape into slim, flat, credit card adjacent bodies, and I wanted to actually understand why before I wrote them off.

I’ll have that full roundup published in a few weeks, but this research is how I came across the G5 in the first place.

What actually made me pull the trigger, though, was the review count. As of this writing, this thing has 5,119 reviews on Amazon, and I have no idea how many units that actually represents, since not everyone who buys something bothers to leave a review.

Whatever the real number is, it’s clearly a lot. That’s a genuinely wild amount of feedback for a niche flashlight, and I couldn’t quite believe it. I wanted to see what all the hype was actually about.

The real test came at Family Camp at Annunciation Heights in Colorado, where my daughter works. My wife and I flew out with five of our kids who still live at home for a family camp weekend.

If you’ve never slept in a classic bunkhouse cabin with seven people, I’ll tell you this: you need a light that can go very dim, very fast, without waking everyone up.

You also need to be able to find it, grab it, and turn it on in the dark without making noise or turning on the overhead lights.

I brought the G5 specifically to put it through that test. We slept in that cabin, navigated the camp at night after late activities, got back sometimes at midnight, and went on a sunrise hike that had us out the door at 4:45 in the morning with headlamps and handheld lights for everyone.

That is the context. Real use, real conditions, real inconveniences. Not a parking lot beam test.

What I Actually Like About It

Let me give credit where it is due, because there are things about this light I genuinely think are well executed.

The rotary dimmer is the standout feature for me. You spin the wheel and the light responds immediately and smoothly. No button combinations, no cycling through preset modes, no holding anything for three seconds. You just turn it. At 2 lumens it puts out just enough light to find your boots in a dark bunkhouse without waking five kids. That is exactly what I needed and it delivered.

The rotating head is a genuinely useful design choice. Being able to stand the light on its magnetic base, rotate the head forward, and have it act as a work light or a lantern gives this thing a versatility that most traditional handheld lights do not have.

In the cabin I propped it up on a shelf with the head angled across the room and used it as a soft ambient light while I quietly got my running gear on at 5am. That worked well.

I do want to temper the magnetic base claim a little. It works. You can stick it to a metal surface and it will stay. But the magnet is not strong. It is not going to hold on a vertical surface under any real vibration, and it is not going to feel bombproof if you try to hang it from the underside of a car hood.

Think of it as a positioning magnet rather than a locking one. It holds well enough for workshop tasks where you control the environment, but do not count on it if the surface is anything less than perfectly flat and still.

The RGB function is something I would not have asked for and honestly would not think to use on a camping trip, but I can see the appeal for certain uses, signaling situations, or just the novelty factor.

Cycling through colors is easy enough and the LED output on those modes is bright enough to be noticeable. I do not think most people will use it seriously, but it does not get in the way either.

At $19, which is what it’s running on Amazon as I write this, the value proposition is hard to argue with on features alone. You are getting a rotary dimmer, USB-C charging, a magnetic base, a rotating head, dual light sources, and IP65 water and dust resistance in a sub-two-ounce package for less than what most people spend on lunch out.

A lot of the complaints I have about this light get softer when I remind myself what I paid for it.

Where It Loses Me

Here is where we get honest.

The G5 is not intuitive. Not even close. And for a flashlight, that is a meaningful problem.

The fundamental job of any flashlight is to produce light when you need it. And when you need it, you usually need it immediately and with minimal thought. You want to grab the light and turn it on. The G5 requires you to think first.

The on/off switch is on the side of the body. Because the G5 is flat and rectangular rather than cylindrical, when you pull it out of your pocket you genuinely do not know how you are holding it until you feel around for the switch.

Every other light I carry is a cylinder. Cylinder lights have one great advantage: no matter how you grab them, you are oriented. The button is at the top or the tail, the beam points away from your hand. In the gear world this is called tactile indexing, the ability to know where a tool is pointing and where the controls are purely by touch, with no need to look. The G5 takes away that orientation advantage entirely.

I reached for this light dozens of times across the weekend and I was fumbling for the switch almost every time. In the dark, in a cabin, trying not to wake anyone, that small fumble is annoying. In an emergency situation it would be unacceptable.

To be clear, this is not a tactical light and Wuben is not marketing it as one. But I think the orientation problem is worth naming because it affects everyday use too, not just edge cases.

The slider switch also adds another layer. To actually activate the LED output, the side slider has to be in the unlocked position before the power button will do anything. That’s actually a genuine mechanical lockout, not just a mode selector, and it’s a smart idea on paper.

It’s the same feature that keeps a light from turning on by itself in a pocket or a pack, which matters more than people think when a battery is fully sealed and non-removable like this one. The irony is that the same slider is also what covers the USB-C port when closed.

So the one mechanism protecting the light from accidental activation is also the one mechanism protecting it from water and dust, and it’s a thin, loose feeling piece of plastic doing both jobs at once.

That is not hard to learn, but it is another thing to manage by feel in the dark. Other reviewers have noted the same learning curve. I got used to it over the trip, but I never stopped thinking about it.

Then there is the USB-C charging port cover itself. This is where my frustration moves past usability and into build quality concerns.

Wuben built a genuinely rugged aluminum shell here, and marketing copy on the product page leans into words like “rugged” and “harshest environments.” But the actual waterproofing rating is IP65, which means protection against dust and low-pressure water jets, not full submersion.

That is a meaningfully lower bar than a lot of buyers probably assume when they see a metal body and hear “waterproof” in the same sentence. And the entire IP65 promise, modest as it already is, rests on a sliding piece of plastic that feels like it would pop open if you tossed the light in a bag or a jacket pocket, which is exactly how most people carry EDC lights.

There is a real disconnect between a metal body that looks like it was built to survive a job site and a charging port cover that does not inspire confidence sitting still on a shelf. I have no reason to think the IP65 rating itself is inaccurate, but the cover feels like a component working against even that modest promise.

A better rubber plug, a firmer sliding mechanism, or a more positive locking action would go a long way here. As it sits, every time I picked the light up I found myself checking whether the cover had slid open.

The pocket clip. I will keep this short: I could not make it work and I stopped trying. It felt like an accessory that was added to the spec sheet more than engineered to function. I carried the G5 loose in a pocket the entire trip.

Who This Light Is Actually For

After a full weekend of real use, I have a pretty clear picture of who the Wuben G5 is and is not for.

It is not your one flashlight. If you are a person who wants a single light that does everything reliably, deploys instantly, clips to a pocket with confidence, and goes with you into the backcountry, this is not it.

The fumble factor and the slider system disqualify it for anyone whose first requirement is immediate usability in the dark.

It is a really solid drawer light, or a car glove box light, or a tackle box light. It is something you keep around the house and reach for when the power goes out or when you need to find something under a couch. The rotating head, magnetic base, and stepless dimmer make it genuinely useful in those scenarios.

As a workshop light you stick to a metal shelf or position on a flat surface while you work, it earns its place. And at $19 it makes a genuinely good gift, the kind of thing you throw in a stocking or hand to someone who always seems to be looking for their phone flashlight.

I will keep mine. I think it is a clever product and I appreciate what Wuben was trying to do with the design. But I will not be reaching for it when I go backpacking, and I would not choose it as a primary camping light again.

There are too many cylindrical lights in this price range that turn on instantly, clip reliably, and require zero thought in the dark.

Where It Lands

The Wuben G5 is proof that interesting features and intuitive design do not always live in the same light.

The rotary dimmer is genuinely good. The rotating head earns its place. The magnetic base is useful within its limits. And at $19, the price is genuinely hard to argue with. Most of my frustrations with this light would land differently if it cost a hundred bucks.

At this price, a lot of it gets a pass. If you go into this knowing it is a novelty item and a convenience light rather than a field tool, you will probably enjoy it.

But the side mounted switch, the non cylindrical body that kills your orientation in the dark, and that sliding port cover that makes you question the waterproofing every time you pick it up are real issues.

They are not dealbreakers if you know what you are buying. They are dealbreakers if you think you are buying your one reliable light for camping, hiking, or any situation where you need to deploy a flashlight fast and without fumbling.

Buy it for your truck. Buy it for the junk drawer. Buy it if you want something fun and different that will genuinely impress people at the dinner table when you spin the color wheel.

Just do not buy it expecting it to replace the cylindrical light on your nightstand. As for those 5,119 reviews that got me curious in the first place, I get it now.

At $19, in the right role, this thing earns the hype. Just make sure you’re buying it for the right role.
