New V3 365nm MINI - Black Light UV Flashlight – High Definition Pure Ultraviolet - Professional Grade High Power Upgraded 5 Core UV LED – USA Stock

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.

This UV light is awesome! I love using this light when I'm searching for leaks on my cars or when I'm doing UV inspections on welds. It works extremely well, and really cuts out all the purple color from non filtered UV lights while still keeping a relatively good brightness and keeping the fluorescence nice and bright. It is super easy to use and very compact. It isn't too heavy at all which is great as well. The charge time does take a little while but the battery lasts a long time, and I have yet to have any issues with any heat for this light at all.

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.

UPDATE: So since venting here I went back and read the instructions. Forgot all about the double click to turn on for user safety. After charging the flashlight it works great. The only probs and reason for 4 stars now instead of 5 is the battery discharge on storage problem and the charging port being set too far in the body making most standard charge cables ineffective at maintaining contact to charge the flashlight. Thought I'd update my review to be fair to the manufacturer. My suggestion for the charging problem; if you can't modify the port to accept standard USB C charge cables, color your included cable a different color than black to make it easier to find. I have a drawer full of included USB C cables, all black from all the electronic doo-dads I own, and trying to find the ONE with the extra 1 mm of depth is a challenge. LOLI purchased this Beast UV flashlight because I was tired of the cheap ones you find everywhere that hardly work. This one promised to deliver and the reviews I read supported that. I ordered and after initial charge, it was indeed, a cut above the run of the mill UV lights you find at local stores as well as on line. Very bright, made sure to use the amber glasses to protect my eyes from reflected UV as the instructions advised to do. It's been pretty much sitting in my toolbox after briefly using it twice to check it out. Now the power switch works about every 4th or 5th time you push it. I tried to charge it assuming it might be due to low battery power, the charging port is not giving me grief and unless I prop the cord against something while charging, will not continue to charge. Disappointed to say the least. I had high hopes for this one but alas it turned out to be another disappointment. Too bad the return window is closed on this one. I can not recommend this for purchase.
