uvBeast V3 385-395nm

Unbelievable amount of UV light from this well designed, heavy duty unit. It is truly commercial grade. We took it to some mines and gem shops and the staff was blown away by the quality and how it caused so many of the gems to light and hold their glow even after the Beast was turned off.I had one issue and contacted customer service for one of the best experiences ever. 5 Stars and I’d give 6 if I could!

I really like this UV light! Well made, durable, and easy to use. A lady recommended it to me at a rock & mineral show. I got it & took it to the upper peninsula of Michigan to hunt for "Yooperlites." And oh did I find them! This light made it so I could find them in deeper water as well as tumbling in the surf! Mine was the strongest light out on the beach. It made my hunt so much better!

This product is awesome.Enormous help in moving out of my rental in identifying issues the management company could have held against me at great expense.I used Folex and erased any suspicious issues. Wish I had had this when I moved into that apartment as well.Highly recommend to take this when staying in hotels too.You can't go wrong.Great investment.

The uvBeast v3 is the most powerful uv flashlight there is. It projects a central spot of 11 degrees with a surrounding fill of 63 degrees. I zoomed my 3 watt 365nm uv flashlight to match the fixed fill circle of the uvBeast and found that even the Beast's fill gives a brighter fluorescence.The uvBeast beam is similar to my 36 watt LED uv bulb as seen in the first picture attached. The Beast has a tighter and brighter spot. I bought the Beast to get more portability than the bulb has with the 10 foot extension cord I attached with a bulb receptacle and switch on it. Since the Beast is temporarily out of stock, I'll let you know that my bulb shown in the second picture is no longer available at Amazon, but I see a similar one at https://www.amazon.com/KINGBO-36W-UV-Blacklight-Decorations/dp/B0749JNZXV/ref=sr_1_7?keywords=uv+LED+bulb&qid=1578421359&sr=8-7I would strongly suggest you buy the uvBeast with the batteries and charger because 18650 batteries have gotten expensive and hard to find. I have not gotten the charger plug led to change to green indicating a full charge. I initially charged the battery for 7 hours. I stopped to measure the battery voltage at 4.22 volts, a full charge. I used the flashlight over a six week period and finally just left in on for another 25 minutes before it dimmed. Then I took a voltage reading every hour while charging the batteries. The result:before charging 3.05 volts1 hour 3.47 volts2 hours 3.52 volts3 hours 3.56 volts4 hours 3.60 volts5 hours 3.62 volts6 hours 3.63 volts7 hours 3.65 volts8 hours 3.66 voltsIt didn't come to 4.2 full charge volts this time, but I've read that you get the longest life from an 18650 battery when you don't fully charge it each time. Seeing how the charging started to level off at 4 hours, and the uvBeast has been working well since recharging, that's how long I'll charge it for in the future.Some reviewers ask what you can do with the uvBeast flashlight. Besides looking for animal urine and spotting scorpions, and checking for the fluorescent ribbon in currency from $5 up to $100, there is lighting up fluorescent blacklight posters, highlighting markers, many green dish washing liquids, laundry detergents, antifreeze, some clothing, and some minerals. If you don't mind being grossed out, aim the flashlight around the toilet in the bathroom or food prep area in the kitchen. I bought a set of 15 fluorescent minerals on Amazon from Frey Scientific, but most such sets would need a dangerous shortwave uv light for most of the rocks. Only 4 rocks would fluoresce as seen in the next 2 pictures.My favorite use for the uvBeast is lighting up phosphorescent glow in the dark powders, tapes, and pebbles, as seen in the next few pictures. I've been doing art with the tape. I found glow in the dark paints to be disappointing.The powders are often shown in bottles but packaged in plastic bags. I bought the bottles separately. The powders come in the most colors, 13, though many are a variation of green, blue, red. My camera didn't capture the true purple color. The longest lasting colors are the three that appear white in daylight but glow green, blue-green, and blue, and one of the reds, as you can see in the sequence of 10 minute exposures. The powder is messy.The tapes come in a total of five glow colors, though the red and orange are similar. The pebbles come in a few more color variations than the tapes. Many reviewers of the pebbles complained that they left them outside in walkways and they didn't glow. They do glow, but the powders, tapes, and rocks, will only glow in color for about an hour depending on the age of your eyes, after which their illumination drops below our color threshold. In complete darkness, you can still see a gray glowing all night long. Pebbles left outside will start glowing once the sun sets and lose their color during twilight that lasts longer than your night vision will see the colors. You need the uvBeast to light them up once twilight has ended.I have received word that they plan to market a 365nm, perhaps uvBeast v4? That is usually considered the sweet spot for uv flashlights, but I don't feel I'm missing anything with the uvBeast v3. A zoom ability would be nice, but taking a step back works just fine.Addendum: Note that I the pictures I refer to are not in the order they were downloaded. I'll number them in future reviews.How powerful is the uvBeast v3? Two or three seconds exposure in the central spot from several feet away is enough to fully charge any phoshorescent glow in the dark item. The most useful purpose for glow in the dark tape is on things you need to find or use in the dark, such as flashlights, astronomical telescopes, light switches, exits, etc.Another uv flashlight use is for collectors to identify depression era glass called vaseline glass, which is actually uranium glass. It is fluorescent in uv light. See the added picture of the doll. It is slightly radioactive, so you may wish to display such items behind glass, which ironically blocks the radiation from such glass.The four hour recharge of the batteries I suggest works out well because the 1 amp (1000ma) charger should theoretically put 4000ma into the battery pair in that time, which totally can hold 5200ma between them. That's about 77 percent charged.I highly recommend the uvBeast v3.

First off, this light is what it says it is, a Beast. The build quality seems to be good, the light "brightness" or intensity seems good. Overall it seems like a well built, heavy duty, light which probably justifies the price tag if it's the type of light you're looking for. In my case, I wanted a UV light source to inspect areas for the presence of scorpions around my property which are common in the NW portion of Arizona. This light was capable of illuminating the scorpions, and it was very bright within it's tightly focused beam. But this is where it didn't justify it's price point for my purposes. I also purchased another UV flashlight at the same time for under $20 which for spotting scorpions under my conditions, worked equally as well. With regular flashlights I am not a fan of the adjustable beam pattern, but with a UV light, for my application, this is where the $20 light really shined. I found that when the $20 light was adjusted to it's tightest beam, it illuminated the scorpion almost equally as well as the Beast. I say almost because it is evident that the beast is a slightly different light frequency than the $20 light that I am comparing it to and luminescence of the scorpion was only ever-so-slightly better with the Beast. But when adjusted to a wider "focus", the inexpensive light covered a wider area which allowed me to scan a larger area and then tighten the beam focus to conform a bright spot. So for my particular needs in finding scorpions, the Beast did not produce a light that was 3 times better than the lesser expensive light that was 1/3 the price. On top of that, the light is quite a bit bigger and uses two 18650 lithium batteries as opposed to just one for the $20, with similar run-times. However, the Beast comes with batteries and a charger whereas the lesser expensive light did not. There are some instances where the Beast will probably "out-shine" lesser expensive light, such as curing resins, or other needs where an exact light frequency is necessary. The only reason I keep using the phrase, "my needs", is that I think the Beast is a good product and I don't want this review to imply that it's a bad product in general, but rather just not that much better for the purposes I described. Happy scorpion hunting!
