The best in show
Legit the best tiny flashlight on the market hands down. Solid construction. Very solid. Has a great weight to it. There’s no question to who the king of bright is when you turn this baby in. It’s super bright. It does get on the warm side but pumping out that many lumens from such a small frame it’s going to happen. The green just fits. What can I say, it just goes with this build perfectly. I’ve used it in so many different situations and it’s not let me down yet a real versatile tool. Battery life does much better than you’d expect given how powerful it is.

Very good mini light
I am very pleased with these lights. They are compact, highly luminous, durable, and can be easily clipped or magnetically attached to various surfaces. While numerous inexpensive options exist, these lights stand out due to their exceptional brightness, quick charging capabilities, and ability to withstand considerable impact. The robust metal construction, including the clip, provides a sense of quality. Although not tested underwater, they have performed admirably during heavy rain. Their versatility is remarkable, offering adjustable brightness from a subtle glow to intense illumination. While the turbo mode generates significant heat and has limited runtime, it is readily accessible with a few quick clicks. The battery life is sufficient for our use as on-off lights, and I have found them consistently reliable. Overall, these lights offer excellent value and robust construction. I have subjected them to drops, drenching, and creek rinses, and they continue to function perfectly.

Great flashlight. Had to buy 18650 3.7v batteries to fit in the extension.
I love this flashlight. It's a little pricey, that's the only downside. I got the whole bundle in green for 40 dollars. The sensor doesnt let you wave your hand, but you just tap the sensor and it turns on. The size of the flashlight is great too, but i also got the extension for the bigger battery. Just bought the batteries for 20 bucks. So im into the flashlight for at least 60 bucks. But I say its worth every penny so far. The light brightness is great too. The dim is really dim, and the bright is really bright. They also have a turbo brightness that is slightly too bright. Thats what I was looking for. When the light is in the headlamp harness you can tilt it up or down. Tilted down puts it at the perfect angle for a headlamp. Actually one more downside is the part that sits on your forehead is not the most comfortable thing, but its still wearable. I would be down to have some padding on it. Also looks like there is a spot to put another strap on the handbags harness. Wondering what that thing is for. I will be back after I test the 18650 3.7v batteries that i got for the extension adapter. Edit: I came back to say that finding the 3.7v 18650 button top lithium ion battery on amazon has been an ordeal. Ive now spent over 50 bucks trying to get a battery to use the adapter on my flashlight. I still dont have the battery. I have a nice case for batteries and a 25 dollar 2 port charger that I got tricked into buying.. if you buy this flashlight and still need the longer battery, go to home depot for the battery. They have chargers too. Amazon has 8 dollar chargers but if they are as big of a scam as the batteries I wouldn't trust it. Any battery over 3500mah is a scam, especially over 5000mah.. be careful out there, China has gotten real good at making fake batteries that work long enough to fall outside the return window.

Pocket illumination powerhouse: WUBEN E7 EDC flashlight with small quirks. Buy before sold out.
This tiny titan is a game-changer for anyone who needs serious illumination in a compact package. At 1800 lumens, the WUBEN E7 delivers absolutely stunning brightness that belies its mini size. What truly sets this flashlight apart? It's rechargeable with a replaceable battery - imagine that! Unlike many lights that become paperweights when the battery dies, this one keeps going. No more tossing out an entire flashlight just because the battery is worn out. It's the kind of smart design that saves you money and reduces more waste. Key Highlights: Incredibly bright: 1800 lumens in a palm-sized device Rechargeable and battery-replaceable / extendable to a larger capacity, no other does this yet. Compact and lightweight - truly fits anywhere Built like a tank, feels premium in hand, tactical like. The magnet is super powerful and does not disappoint. One minor drawback: the hard edges can be a little uncomfortable when carried in a pocket. It's not a deal-breaker, but something to be aware of if you're planning to EDC (everyday carry) this light. I have so ideas on how to handle this, but I have to think the best way to address this. Whether you're hiking dark trails, dealing with a power outage, or just need a reliable light source anywhere, the garage, walking, storage anywhere, the WUBEN E7 won't let you down. Highly recommended for anyone who appreciates practical, long-lasting quality made tactical gear! Not cheap junk made to fail. Pro tip: Keep one in your car, backpack and emergency kit. You won't regret it. At this price buy as gifts, which is what we did and it did not disappoint, it in fact amazed. Also the accessories available makes this light a next level tool, extend the battery capacity and have a hands free headlamp to use anywhere, that you can activate the light with a mere hand gesture. Making this light almost a smart light without the bulk and overly complex design. This is only of the best lights I own, costs are reasonable for once and it outperforms some of my Olights, which costs way too much and even getting close to my Police Issued Streamlight, which is still a fantastic light, but for the size and price, I have not yet seen anything better then this WUBEN E7 EDC Flashlight. I need to mention that the company behind the light, also has amazing customer service and this price point that honestly surprised me and really unheard off in a market where many companies sell products that are turn and burn. That is no the case here, they make really nice gear, a tool that can be used hard and it holds up well. Can't wait to see what the company creates in the future ....

Great EDC light with many uses, minor fixes would make it perfect.
I bought this light after owning Wuben's X-0 for nearly a year. In many ways, this model is an improvement-- cheaper, better switch that doesn't accidentally activate as easily, better pocket clip, toolless removable battery cap, etc. On the other hand, it misses a few things that I'd like to see improved upon. First off, there is no moonlight mode like the X-0. This is sorta big to me, as I'm often using the light in a totally dark bedroom or dorm at the station. Second, mine failed to charge after a month and the battery would drain crazy fast. To Wuben's credit, they sent a replacement that seems to be working fine to this day, but my X-0 has been chugging along without issue for over a year-- maybe I got a lemon. Now here's some general things about this light that makes it a good pick: first, it's a right-angle light, so it can light your work area from a backpack strap or belt. Also, since it has a spring steel clip, it'll easily clip on to a variety of thicknesses. The tail cap magnet is strong-- I use it to hold papers up when typing reports, light up equipment compartments, and even tied cord to the light and lowered it through a storm drain to retrieve dropped keys. The angles on the body allow you to position the light, and it can take regular or rechargable batteries-- the latter of which can be charged in the light with the ubiquitous USB C cable. The light itself is more floody than beamish, which is useful for the majority of EDC work in my opinion.

Good EDC light.
Easy operation, solid build, well designed, and inexpensive. The brightness level is impressive especially for a flashlight this small. I also like the different light modes, they are useful and practical. The advertised run time seemed to be accurate (at lowest level, about 50 + hours). Charging is fast and the battery is removable, this means you can have a spare battery that will allow you to run this light longer. Another good thing is that you don’t need to buy a proprietorial Wuben battery, you can use any 18350 batteries. Finally, it has the right weight and size, perfect for EDC. This is definitely one of the best Chinese made flashlight in this price range ($20+). Highly recommended.

Good purchase, good price. Love it
This light is awesome. I’m very impressed all around. After buying some other work lights to use in my small engine repair company and them not charging out of the box brand new, and being too big and built with poor quality materials I decided to go the EDC route and I’m happy I did. It’s small enough and has a magnetic base to place on anything anywhere on an. Engine and the side facing light adds to that functionality. Even the non magnetic sides have angles that allow a 45 degree or to lay flat. The brightness is ridiculous. Especially the turbo mode. It’ll literally blind you. This could be used in a self defense manner. If the battery stops charging prematurely, there’s a year warranty and if I have any issues I’ll update.

Great battery, extremely bright, and very durable
Bought this flashlight last year as a work light. It was perfect for carrying in my pocket as I crawled through crawlspaces while doing plumbing work. The magnetic base makes for great handsfree work light. Surprisingly bright for the small size with an impressive battery life to boot. I liked it so much that I bought a backup as a just in case.

Great EDC flashlight
I went for the extension tube right away and put a 3400Mah 18650 battery in it, one of the best little flashlights I've ever had.

Ótimo para enfermeiros em seus procedimentos que dispensam tocar a lanterna para acender ou apagar.
Ótima conectividade. Funcionou perfeitamente, me ajuda muito no momento dos curativos onde estou de luva e não preciso tocar para ligar ou desligar, a lanterna ficou top, consome mais bateria quando conectado mais ainda sim é extraordinário e ao meu uso extremamente necessário e eficiente.
