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

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.

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 light for my husband and we read all reviews. He had one of the little lights and wanted a bigger one. Shipping was fast. He got the light and had an issue with it. It was turning off within 5 minutes of being on.I contacted the company by email and got a quick response. They asked for some information and said that they were going to send another light right away. It will be here today. I highly recommend this company and their products. Sure there’s going to be some faults in any products. This company will make sure you are getting what they advertised and the customer service is excellent. I hope this helps for anyone who is looking to purchase from

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.

Don’t even think about buying any other UV flashlight for serious use. This thing totally outperforms prior ones I had purchased for prices ranging from 14 to 26 bucks. Night and day difference. It has the right wavelength, and lots of power. It’s also well-made and I think it will last a very long time.

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.
