uvBeast V3 385-395nm Black Light UV Flashlight - High Power Upgraded Triple Broad Band LEDs Best for Professional/Commercial Use - USA Stock

Great product! Been reliable so far, very bright (even visible during the day), and you can always get a different charger or battery if needed so I'm not worried about those underperforming when they get old. Cheers.

I purchased this light to aid in hunting tomato hornworms in the garden. I'd heard that they glow in the dark under a black light, and was willing to try anything. I'm extremely pleased to report that it works like a charm. They glow bright green, and are easily discovered and disposed of. Now I just go over my plants with this light every evening, and haven't lost any plants since!

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=8-7 I 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 volts 1 hour 3.47 volts 2 hours 3.52 volts 3 hours 3.56 volts 4 hours 3.60 volts 5 hours 3.62 volts 6 hours 3.63 volts 7 hours 3.65 volts 8 hours 3.66 volts It 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.

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!

Our old scorpion hunting light stopped working after one of our grandkids threw it, so I had to get us a new one. I decided to spend more for a newer and better UV light. Our neighbors changed their landscaping and the scorpions decided to come to our lot. We have a small dog and I'm allergic to be stings, I'm not sure about scorpions, but I don't want to find out. My wife was stung 3 times by 1 scorpion when the old neighbors put their landscaping in. We never saw one before then and it was 9 years between seeing them again. In conjunction with an exterminator I felt that I had to locate any scorpions on our property and dispatch them promptly. With this light I was able to see them from long distances. That helped me so that I wouldn't miss one or get stung by one. It's an excellent light with one drawback for me. The handle is very thin which causes my hand to tire easily. It also did the same with my wife's hand. It is very solidly built. I like that it is rechargable. I got tired of getting battery after battery for our old scorpion hunting light. One thing I just thought of last night. I went to use my light but it needed to be charged. I went to connect the flashlight to a usb-c charging cable. I was disappointed that there wasn't a place where the batteries could be charged up directly INSIDE the light body. I had to remember where I put the separate battery charger and totally forgot. Once I got it I set the charging container on a shelf near the outlet. That is another thing aI find disappointing. You have to use the attached cable to charge the batteries. It would be better if it was able to use a standard usb-c cable. It most definitely will be longer than the short cable that is a part of the container. I really find this frustrating and a big miss, especially for the price the light is and the suburb build of the light. I bought smaller UVs and they had a slot for a usb-c cable to charge the light.

I have had many UV ligjts over the years. Most of the lights had a dozen or so small leds to nice rechargeable UV lights but had a UV filter and not true UV leds. I use my lights for multiple reasons. Example uses are to find scorpions, looking for Uranium Glass in yard sales to automotive work to find oil leaks to refrigerant leaks. One big use is for using UV resin. My other lights worked well for curing the resin. Since I received this light it puts all other UV ligjts I have purchased to shame. It is extremely rare for me to order a product then once the item is received it far exceeds my expectations. I almost gave this item 4 stars instead of 5 due to the battery charger. The charger sucks. Luckily I have a proper charger. I decided not to ding this item cause of the charger and just focused on the light. Thank you for the awesome product.
