uvBeast V3 365nm Black Light UV Flashlight – High Definition Ultraviolet - HIgh Power and Long Range Professional Grade Beam Best for Professional/Commercial Use – USA Stock

Just get it. I have many of these black lights that advertise showing cat urine, etc., and they do not work well or at all. This is not the case for this light. Best in class, hands down. It is sturdy and works a little too well, if anything. What I like a lot is the ability to use an extension to use three 18650 batteries for longer life, and it works just as well with the included two 18650 batteries. I had other 18650 batteries and use three in mine using using the included extension. The main use for me was detecting areas of carpet around the litter box that may need to be shampooed, and when I walked around the house, the results were amazing and yet disturbing. I am a clean freak, and this simply will let you see what your eyes don't. So if you want a truly clean house, this is a must :) PS. For those unfamiliar with NM values. Don't be fooled into thinking a higher value is better. Lower is better, depending on what you want it for. 375 is ideal as it is a more pure uv and does a better job detecting scorpions, pet stains, forensics, currency verification, and things like that. 395 is ideal for Halloween/party effects, glow in the dark, and casual use. Hope this helps. As the saying goes, you get what you pay for. Amazing product and again, be prepared for what you will see!

This is an absolute BEAST! Super heavy duty build: very sturdy and strong, comparable to mag lite brand. UV is super bright, working even in “visible light” settings. But this thing SHINES in the dark ( 🤣 I’m so clever, aren’t I? 🤨🤷🏽‍♂️). Triple beam lights up all those secret bits and pieces you would normally never see! Be warned, you will be disgusted with yourself and your living situation when you see how much you don’t actually see! You may end up scrubbing every inch of every wall in your home after using this AMAZING UV flashlight. Battery life is pretty decent, and can be expanded to hold 3 batteries for extended usage. The two batteries and charger it comes with are generic but I have no complaints about their operation. I assume you could get more usage time by upgrading the batteries. All in all, I absolutely love this thing! Super heavy duty and super effective! I could not be happier with this purchase! And I have found an extra, unintended use for my UV flashlight: that it is very useful for finding tiny seed beads dropped onto the carpet! As much as I have hyped this up, I am still confident in my opinion and stand by my words 100%. I assure you I do not benefit by sharing my opinion and is merely an attempt share information I wish I had before I purchased. Wishing you and all of your the very best, Always. You matter! You are appreciated!

Professional quality, solid and durable. Very bright; you can see everything. Easy to grip. Batteries last a long time, then just recharge with included charger. Well worth the money.

When I received the Beast I was super excited. Unfortunately during shipping the unit was damaged and wouldn't work as it should. I reached out to the seller and they got back to me immediately (always a concern) and they were a pleasure to work with. They sent out the replacement and it arrived next day working perfectly as expected. The light is next level in power and perfect to use for rock hounding and IDing minerals and stone formations. I'm sure that I will find other uses as well after walking around my house and seeing things in a different light, no pun intended. I had used smaller cheaper versions without much success, the uvBeast V3 365nm really opened my eyes to the true power of UV and I know it will do the same to you. This is real Ultra Violet with a controlled wave length that will light up what others don't. I am 100% sold on this product and their customer support is the best in every way. This is a company I will do business with again and knowing if there ever is a problem they will make it right immediately and that is an added value that is as important as the product itself to me. Both are great!!!

So far its well built and lives up to its name. It provides a fairly tight spot of UVA light that projects for quite some distance, which would be useful in mineral hunting. Also does a very good job of exciting fluorescent paints and glow powders. The flashlight itself is also nice in that it has a dedicated driver module for maintaining fairly constant intensity even as the battery voltage changes. Additionally it has generous heatsinking as well as a filter that also passes infrared so it can be run for decent lengths of time before getting too hot. Only potential drawback is that the beam width is fairly narrow, but for its intended use its good. Also very, very bright, so protective glasses that block the UV itself are definitely recommended. Even off to the side the LED chips are quite visible through the filter with a deep violet glow coming from their vicinity, so the beam itself could cause eye damage without protective glasses if it reflects back off of something like glass or a mirror. Overall very nice.

Bought one of these a year ago after being frustrated with cheap flashlights with the wrong frequency. The 365 NM is the one you want for highly illuminated Uber light rocks and other UV items that will glow. I bought a second one and I have found that I can find yooper light rocks that others walked right past. I know if everyone that goes up north is equipped with one of these there won't be any left for me but it'll be worth it because this company sells a quality product and backs it with excellent excellent customer support.

In a separate review, I gave a glowing review to the $40 "Little Brother" version of this light. Well, the "Big Brother" is no less deserving! I've had it for about 9 months at this point, and have used it everywhere I go. As someone who collects stones (both raw and shaped), and who also loves UV-reactive things universally, this light opened up a whole new world for me. Prior to this, I owned a 385-395nm light, which I enjoyed...BUT, it has a lot of limitations. For one, being much closer to the visual range, it gives off a lot of visible light in the pink and purple hues, which overwhelm everything in its beam, and makes photographing the UV reaction next to impossible, as it overwhelms the camera lens. Second, there are a limited number of stones that react in that wavelength range (I've seen 2-3 dozen, give or take, so far). But at 365nm, BOTH of those issues are solved. There is still a small amount of bluish light visible, but very small compared to the higher wavelengths...so the visibility, details and ability to photograph are all IMMENSELY better. And the number of stones/minerals that react at that specific wavelength is EXPONENTIALLY greater--I have well over 100 different stones in my collection so far, and there are hundreds more...PLUS, all the stones that react at 385-395nm ALSO react at 365nm. So in every way, a 365nm light is hands-down the far better choice for those who love UV. After that, which light is best for you depends on what you plan to do with it. If your viewing of UV is generally limited to stuff in one room, or stuff within arm's reach, the "Little Brother" version would probably do just fine. But for me, I like POWER. I like the ability to take my light outside on hiking or mining trips, and spot UV-reactive stones at a distance. So with both my 385-395nm light and this one, I chose to go with the bigger, more powerful (and therefore, more expensive) version. But I haven't regretted that decision one bit in the 9 months since I bought it. The 2 batteries that come with the light are a unique size (not AA or AAA as many lesser lights tend to use), but they last a long time during constant use (4-6 hours on average), and are rechargeable. From empty, they do take a while to fully recharge, so I recommend buying an extra set of batteries (which is something I do with ANY and EVERY electronic device I own), so you can have 1 set to use while the other recharges, or to extend your usage time when away from places to charge. Two sets of batteries will last you most of the day--8 to 12 hours, depending on usage. The only downside is, the longer you use it, the hotter the grip gets from the batteries heating up, almost to the point of becoming uncomfortable to hold. But if you switch it off when not in use, and take a break every little bit, that shouldn't be a problem. You can also get the smaller version, which only requires 1 battery (which can be charged inside the light via a charging port in the side of the light body), and doesn't have anywhere near the heat output of the larger, more powerful light. So it all depends what you want out of your light. I prefer power, so I chose the larger light. But having bought the smaller one for 4 friends, all of whom absolutely LOVE it, you cannot go wrong with either light. But having seen and used more than a dozen different UV lights of all kinds and qualities, for me, UV Beast makes the best ones for the money. Yes, there are cheaper lights out there...but they also have more issues--power, flickering lights, go through batteries like candy, etc. So if you want a top-quality light that works well, is rechargeable, and provides you a choice between small & convenient, or large & powerful...UV Beast is my recommendation, every day of the week. And that sentiment is universally shared by everyone I have either bought the lights for, or who has bought one themselves based on my recommendations.

This thing is incredible. I've had a few UV lights before, so I wasn't expecting this to be such an upgrade in terms of power and what it'll make fluoresce without overwhelming with purple visible light. Just be careful, as being able to see every invisible stain in your house since it was built is a disgusting experience. With great UV power comes great responsibility.
