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.

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 deviceRechargeable and battery-replaceable / extendable to a larger capacity, no other does this yet.Compact and lightweight - truly fits anywhereBuilt 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 ....

Very floody
I think this flashlight is a good value for the money. Not very comfortable as a keychain because it's pretty heavy, and you would need to supply your own ring in that carrying method since it does not come with one. Out of the other flashlights that I have it compares to a Nitecore TUP in terms both of size and brightness. But the Wuben E7, while shorter than TUP, is a lot heavier than it, because of its machined aluminium block construction, as opposed to pressed sheet metal and inner plastic frame. This means that the E7 will be a lot more durable, to which adds the fact that it has a ridge around the lens. E7 remains lit at high setting for 1.5h on the stock 1100mAh 18350 battery (you can buy a higher capacity one or a tube for an 18650 if you want more battery life). The flashlight seems significantly less bright than it is because of its wide emission angle (a lot wider than Nitecore TUP). You only see how bright it is when illuminating an area with it or some other light source. But do not expect a pocket sun, it is pretty bright but won't make the entire room look like it's suddenly day. Turbo stays on without holding down the button and then it switches to high. The button is at the end and has a ridge, both of which make it hard to press accidentally. You technically can wear it on a hat, but you would have to put it on the 90s skater kid way (the beak facing backwards) and use the adjustment strap as mounting point. For handsfree use you either want the custom headband, or put it on your belt or shirt collar. It will wobble on soft clothes though, because it is heavy and short. Probably the 18650 tube would help with that. The flashlight does get rather warm when on in high mode. I like how you can not only replace the battery easily with common sizes, but also take the rest of the flashlight apart for some mods or component replacement if you know what you are doing (it has screws and you can access the LEDs and the controller). Magnet is strong making it a good work light when combined with the LEDs being on the side instead of the end.Pros:- bright, similar (somewhat worse) battery life to lumens ratio as the first gen Nitecore TUP, durability, build quality, repairability, wide angle (when used as a work light), easy to use UI, strong clip and magnet, option to be a longer flashlight with more battery life if you want it to, turbo does not require holding down the button, the flashlight does not know whether the battery is an 18350 or 18650, so it has the same brightness (possibly limited by battery ESR in turbo mode) regardless, and it is really cheap for what it is, you can get the battery out to prevent self-discharge when not using for a prolonged time, looks good.Cons:-less bright than I expected, really heavy for its size, may not charge from some smart chargers when using USB-C to USB-C cable (to use an USB-C - only charger that won't charge it, you need a USB-C male to USB-A female adapter and an USB-A to C cable to strip out the USB-C - specific signalling. The flashlight works normally with at least one of my "smart" chargers with USB-C PD, but not with the other, needing this workaround), can't wear on the beak of a baseball cap in a useful way, could have more brightness modes, maybe too floody for an EDC flashlight.As for the 18650 extension tube: it is just a tiny bit too long, so the flashlight can turn off when shaken violently with at least one brand of 18650 inserted because it is loose. And the tube is just that: a tube, not a longer endcap, so don't get the idea that you will have a long endcap to use at home with 18650s and a short one attached to your keys, to use with 18350s. You still need the original endcap. And the thread on the tube is not as thought through as on the flashlight itself, so when fully screwed in, the walls on it do not match the walls of the flashlight (unlike the non-extended flashlight that looks good when fully screwed in). I think it is brighter with an 18650. Also be careful with the TIR lens as it is easy to scratch.

E7 light clips on secure, no padding on back of mount plate..uncomfortable on head
if you have the E7 light and want a way to use it hands free, this is a good option.I will be using it for night running as the E7 is far superior and smaller than a regular flashlight or any of the running lights I see for sale.The E7 clips into the band securely and can swivel up and down. there is a notched rotating piece so that it locks into place, it will not move up and down while running, it will stay in the position you set it at.My only complaint is the back of the hard plastic mount plate does not have any cushion or foam, If you have this band on your head w/o a hat or beanie, it is uncomfortable. The plastic just pushes against your forehead.For 10 bucks they could have put some foam or cushion on the back. This is meant to be worn on your head, not sure what they were thinking.-1 star for poor comfort at the mounting plate area. The rest of the band is very nice and comfortable, seems well made and the writing on it is reflective (good for running too).This does hold the E7 very well, and I dont think another option would be better, so I'll keep it...when its cold out I can wear it over a beanie, but for all other times I'll end up installing my own foam so I dont have an indentation on my forehead after using this product.

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.

Really good flashlight with a great beam
This is a really good flashlight and the Green body color is very nice!First, this flashlight puts out a lot of light in a broad beam pattern which is great for walking at night. On "Turbo" it has a lot more throw than I expected for a light this small with its small reflectors; It will light up a tree or something similar at ~100 yards while still retaining a beam that is useful for lighting the path you are walking. On Turbo, this light will get warm pretty fast so, something to keep in mind if you are looking for sustained use at long range. Moonlight/Low mode is great for a dark hotel room or late night run to the bathroom so you don't disturb others. Medium and High modes are great for normal nighttime walks or looking for a misplaced item in a dark car trunk and similar uses.The size and form factor make this flashlight very easy to hold, use, and keep in a pocket or bag. Its small size and shape let it "disappear" when not needed while still retaining an easy-to-use form factor when you need it.I use the clip to attach it to my shirt collar when I need both hands free where it rides well and lights up the path I am walking or anything I am working on. The magnet base is very useful on a car hood or the engine when you are checking something at night and need more light than a single dim hood light can provide.In terms of runtime, the battery has about the same general capacity as a normal AA cell so, if you run it for long periods of time at high power levels, you will run the battery down. The good news is that it is easy to recharge, in my case with my cellphone, with a USB-C connector so, not really a concern for me. For someone forgetful, keeping a small battery charged could be a concern. However, on the non-Turbo modes, run time is very good for a battery this size.Overall, a great flashlight with great output for its small size, with good runtime for such a small battery, a great user experience with its great beam quality, a User Interface that is intuitive to use, a good clip and magnet in the base, and overall great build quality.-----------------------------------Added October 7, 2024I have been using this little flashlights a lot. It is super handy for general household uses and "out and about" while walking in the evening or while traveling when unloading the car in a motel parking lot and similar things. The small size and broad light output is very handy in everyday life. The width of the beam is very useful for finding things that may have been dropped or avoiding obstacles in my path at night. The battery may be small but, in my use, has never been a problem having never run out of power. It pairs well with my cellphone charger in the car too so, it is super easy to top off the battery when I have an evening outside.

Incredibly bright and compact - magnetic base is perfect for hands-free work!
This WUBEN E7 rechargeable flashlight is absolutely phenomenal! At 1800 lumens, this compact light is incredibly powerful - it illuminates spaces far better than flashlights twice its size. The brightness is truly impressive and rivals much more expensive tactical flashlights. I love the 6 different lighting modes which provide excellent versatility for any situation - from a low mode for reading maps or finding things in a tent, to a high mode that can light up an entire backyard. The strobe mode is particularly useful for emergency situations. The magnetic base is brilliantly designed and one of my favorite features - it sticks securely to metal surfaces like car hoods, toolboxes, or metal shelves, leaving your hands completely free to work. This has been invaluable for auto repairs and working in tight spaces. The compact size makes it incredibly portable - it fits easily in a pocket, glove box, or tool bag. The rechargeable battery is a huge cost-saver compared to buying disposable batteries, and the USB charging is convenient. The build quality is outstanding with durable aluminum construction that feels solid and well-made. It's survived multiple drops without any damage. The battery life is excellent even on the highest setting. The beam pattern is well-focused with good throw distance. Perfect for camping, emergency preparedness, automotive work, or everyday carry. Exceptional value for a professional-grade flashlight!

Super bright -bad battery
This light is super bright and compact. It is great for camping, hiking, and in general doing things around the home. The fact that it is rechargeable was a bonus. It is built solid and has some heft for its size and has a metal clip that holds up well.After about 1 year of use on and off, the battery no longer holds a charge. I can charge it all day but when I go to turn it on the flashlight only blinks the low battery indicator and gives up the ghost.

Piccola ma davvero potente!
Sono rimasto molto soddisfatto di questa torcia. Fa davvero tanta luce nonostante le dimensioni compatte e lo strobo è molto potente, quasi da sembrare una funzione di autodifesa. La batteria, per il momento, sembra avere una buona durata, ma la sto ancora testando.L’unica cosa che non ho ancora capito bene è la funzione SOS, che non mi è chiarissima e dovrò approfondire.Nel complesso, ottima torcia, ben costruita e molto pratica. Consigliata!

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.
