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!

Incredibly bright in UV; barely any visible light output at all. Exactly what I was looking for. I am a driveway mechanic as needed, and it’s darn near impossible to see leak dye during the day with a cheap uv light. This thing? I’m scared it’ll cause cataracts if I stare into the beam. It’s is a flaming torch in UV, that’s for sure. Leak dye practically explodes with fluorescence.Love that it has removable batteries instead of the ubiquitous usb-c port that every electronic device from “there” has these days. Means I can pop them out and put them in my dedicated charger, or, gasp, replace them when they’re old and stop holding a charge. What an idea!Worth four times more than the competition? Eh, I’ll use it once or twice a year, but I know it’ll be there and work when I need it. That makes it worth it to me.

If you are hunting scorpions, BUY THIS LIGHT! It's unfair asymmetric warfare against scorpions. They don't have a chance. There is NO HIDING from this light. I live in a rural area and hunt scorpions nightly and truly I feel a little guilty because they can NOT hide from this beam. The carnage is apocalyptic.Eventually, those that are left are going to rise up and it'll be all out war but thankfully, they'll have to call in reinforcements because I decimate their numbers nightly and this light is a critical part of my armory. The second most critical part is my shoe.

I purchased this device to rock hunt emberlight. Not only is it a great light, its durable and has an impressive use period. I usually carry a spare battery while I am walking the beach at night. I tend to rock hunt for 5-6 hours. I no longer carry a spare battery as the light has provided enough power to cover this amount of time. For all transparency, I use the light for about 5 hours, and turn it off while I take breaks. I recently borrowed the light to a newbie, who dropped it immediatly after I handed it to him. I replaced the battery, opened up the device and checked the connections, and it did not power back up. I contact support to ask how much it would cost for warranty repair, and to my surprise, they are sending me a new light! Rarely do I have this experience! Exceptional customer service! I have roughly 2K in UV lights and never have I had such exceptional service!

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 beThe 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.
