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!

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.

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!

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.

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.

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.

I bought this in preparation for an upcoming coolant leak job that has been so far impossible to find. It arrived quickly and I was surprised by the size and weight of it. It feels substantial in my hand but not cumbersome or excessively heavy. It is about 8.5 inches long in 2 cell configuration or a bit over 11 inches in 3 cell configuration. It appears to be a great quality product designed to hold up for years of use and is even double O-ring sealed. I don't know if it is water proof and I don't plan to find out on purpose but it should be water resistant enough that I wont have any worries about using it in the rain if need be The only thing I have found about it that I would ask to change is to have some flat spots machined into the outer circumference of the head so it is not so prone to rolling away if you lay it down. Since my job isn't schedule to be here until next week, I decided to play with my new toy for a bit. Let's just say I will never take it to a hotel, I'd rather remain unaware. I saw stuff in places that made me scratch my head as to how something could get there! Some places I expected such as around the cat's litter box, but not 7 feet up on a wall in a rarely used room. After becoming grossed out at some of the places and how much showed up, I decided to focus on other things. I can see this being a great prop for a CSI cosplay or Halloween costume. I had a pair of saloon type swinging doors that were recently installed going into a utility room, won't make that mistake again but that's unrelated. The doors looked good, until I put the UV Beast to them. The stain that was applied to them looked like it had been put on with paint brush or something! You could see the direction of the strokes that were used to apply the stain! Not only that but you could see what I can only describe as florescent marker scribbles showing up thru the stain! I certainly see how this could be useful in appraisals of certain artworks. I even noticed that knots in wooden posts around my porch glow. I've used it on money to see some of the hidden features used to thwart counterfeiters. I have not used it to hunt minerals or anything like that but I can see that this thing easily has enough power to make things react in daylight based on my limited use so far. I don't know how long it will run on the included batteries before needing a recharge as I have not used it continuously yet to the point of it needing to be charged. It does come with an extension barrel to make it hold a 3rd battery to increase run time if needed. The only problem is you will have to find a different source for the batteries as UV Beast does not sell the batteries. Thankfully you can go to the company's webpage and they do tell you where to look for quality extra batteries. I do plan to buy extras and a charger so that I should always have a set of fully charged batteries ready to go. If you don't plan to use it a lot you may not need extra batteries but if you do plan to use it for work I would recommend the extra batteries and charger. The supplied charger works ok, I do sometimes have to roll the batteries after putting them in the charger to get them to make contact so they will charge. If you do plan on a third battery I suggest a charger anyway since the supplied charger only charges 2 batteries at a time. Overall I think this is a great light that has many uses and is powerful enough to be used in most conditions. Again, the ONLY thing I would want to change is to add some flats on it to make it not so prone to rolling away and that is just a minor inconvenience, not really a problem unless it rolls off a high enough place to damage the light when it lands. It's something UV Beast may want to address on any future versions but it's not a deal breaker on this kind of light.
