Super fast shipping. We bought it for the business to check paper currency. It’s working very well. It’s very bright. Hopefully it lasts a long time. I’m sure it will. Thank you very much

When's the last time that your new flashlight came with an owner's manual? Did it have a wonky section that boasted about the design choices? Did it have an actual, coherent troubleshooting section? This one does. This flashlight deserves a great manual. After all, it's a great flashlight: solid machined body, USB-C charging port, and a narrow-band 365 nm pass filter. And the beam... this thing is dim... until you shine it on something fluorescent! Holy cow!. You realize how narrow the human visual spectrum is. There is a ton of UV emitting from this flashlight, but it's not visible. Turn on this beast; depending on what you seek, you may be thrilled or mortified. Walls and floors that look spotless light up with dust and stains. OTOH, lots of things light up in unexpected and delightful ways. Take a nighttime hike with this device; you'll see bright blue-glowing centipedes, yellow fluorescent mushrooms, scorpions (if they are indigenous). Limitations? Keep in mind that the beam is long-wave UV. It will still make some rocks in your fluorescent mineral collection light up, but it won't be the colors that you see in the museum short-wave fluorescent mineral case. For that, you need an SW unit, 10x what you pay for this flashlight, and not portable. Heat level? The UVBeast V3 mini gets pretty warm after a few minutes, but not hot. The lithium battery is replaceable if you exhaust its charge/discharge lifespan.

I have found this UV flashlight to be the gold standard! I collect Victorian EAPG glass as well as vintage vaseline and uranium glass and a good, strong UV flashlight is my trusty sidekick in identification! Over the last year, my father's health began to fail and I spent most of my free time caring for him at his home until his passing in early November. I put the 'beast' away in a safe place, aka where I couldn't find it. Over Christmas, while looking for my grandkids christmas presents (which had suffered a similar fate), i found the Beast again and put it on charge. After twelve hours of charging, nothing happened. I tried for a longer time with the same result, went to the website and made sure that I had followed all of the troubleshooting steps and then wrote to the company asking for help. Seb, the Customer Service representative who corresponded with me, wrote me back within a day and gave me a couple of other suggestions to see if we could get it up and running, but to no avail. I wrote him back last night with the result and by this morning, in my inbox, he had written back telling me that they were expediting a new flashlight to me! I was floored. I have truthfully not encountered that level of customer service in what feels like forever, if ever! The kindness and non-judgmental advice added to my experience greatly. This is a company that stands firmly behind their exceptional products with exceptional customer service and I wouldn't hesitate for one second to recommend both the flashlight and the company to anyone looking for a similar device!

I'm dissapointed in the length of time the battery actually lasted before it went bad and wont charge, I have similar products like my stream-light and the batteries lasted YEARS before I had to replace one, I mean so long I cant remember 10 years possibly longer. this battery didn't ,make much longer than a year, out side of that, the light worked pretty darn good, I used it it in hard to get places for leak detection for coolant and oil leaks with dye put in the system, could it be a little more powerful, perhaps, but in most all cases I could use it in fairly bright situations even several in broad daylight to see the dye glow well. I literally did not use the A/C powered one at all until this battery would not take charge, and it was like out of no where, it just would not light up at all, BUT Id have to say Id give it a solid 4 stars I was pleasantly surprised particularly for this items price range, sure better than dragging out the extension cord and pulling out a 6in diameter gun style huge UV light, you just do not run down to your local store to replace this battery either, so i still have not done that. debating replacing it with something different but haven't taken the time to see what else is comparable. but i ran into a situation where getting the job close to power is not possible. so I need to do something, wish it was easier to get a battery

Note - the photo submitted is not for its "beauty" but to illustrate a point. This light does put out true UV, and a goodly quantity. The picture submitted is of a pink rose bloom at a distance of 12 inches (measured). This was shot in a darkened room. I used a Pentax KF full spectrum (Kolarivision modified) using Pentax 100mm ED AW macro. ICE UV filter. ISO 12800, 1/200 at F3.5 and -0.7ev. The K3 is very bright, and the light was un-difused so the hotspots on the (very) reflective rose necessitated -0.7. I used an 18% grey card to white balance, producing a nice grey image. I did some grain reduction in Topaz Photo AI. OK all the tech stuff is over. What I like: the flash is rugged. It has a good heft a weight. I used a light stand and clamp to hold it. This is not a cheap plastic barrel, which I appreciate. My intended use is photography both indoors and outdoors. Indoors for some fun ultra close work; outdoors as "fill". The button on the barrel has a nice solid "click". It came with an extra extension tube - for a second battery? The output was reasonably even, but I may use a diffuser in the future to avoid harsh shadows. I had it on for about an hour adjusting light, etc. No problem with battery life. The unit did NOT get hot in use. That bodes well for longevity. Frankly, I would like this company to make some photo oriented light boxes - something square, maybe 4 to 6 inches on a side for macro work. They really have a great product and I appreciate quality. Oh, and it really is UV. My other cameras did not pick up a usable image. Only the full spectrum camera, and it definitely was UV.

I’ve been using the UVBeast V3 365nm Mini for the last month, and I’m genuinely blown away by how much performance they’ve squeezed into such a small package. This little powerhouse slips effortlessly into my pocket or toolkit, yet delivers the same high-definition 365 nm UV output you’d expect from the larger, bulkier models. From detecting pet stains on carpets to verifying currency authenticity, the beam is crisp and uniform, with virtually zero visible-light leakage thanks to the precision-filtered optics. Charging is a breeze—simply plug in the included cable and walk away. No fiddling with cap threads or hunting for a special charger. After a full charge, I routinely get over two hours of continuous use, and the upgraded LED cores keep the output rock-solid throughout. The double-click on/off toggle is a small but well thought out touch, preventing accidental activation when it’s riding on my keyring or stashed in a pocket. Build quality feels truly professional: the anodized aluminum body is lightweight yet robust, and the knurled grip gives you confidence when you’re pointing the beam into dark corners. Customer-driven refinements (like the wider beam angle and accidental-operation protection) really shine in the field. If you need a go-anywhere UV light that doesn’t compromise on power or convenience, the UVBeast V3 365nm Mini is hands-down the best compact UV flashlight I’ve ever tested.

It appears as though I am not alone in the "stops working entirely" group. I purchased this UV flashlight in October 2024 to use periodically for rock & mineral club field trips (translation: very light use a few times per year). The flashlight was used only a few times, needed recharging often (when it was actually needed, it was only usable for a few minutes before it already needed recharging), and was not nearly as bright as a much lower cost, unknown brand model I had also purchased as a comparison to this known brand. After a handful of cycles, the unit stopped working entirely, as other reviewers have also reported. I expected much better from this brand. Needless to say, I was unimpressed. and disappointed in this flashlight. Would I recommend? No.

This uvBeast V3 Mini 365nm UV flashlight is a game changer. It works exceptionally well for detecting pet stains, revealing even the most stubborn spots that are invisible to the naked eye. The build quality is top-notch, with a sturdy aluminum body that feels durable and reliable. Its compact size makes it easy to handle and store, yet it doesn't compromise on power. The rechargeable battery ensures long-lasting use, and the 365nm wavelength provides a pure ultraviolet light that enhances visibility without the interference of visible light. Overall, this flashlight offers excellent value for its performance and build quality. It's a must-have tool for pet owners and anyone needing a reliable UV flashlight.
