Excellent UV Flashlights & reasonable price.Purchased these to use for finding small white boxes used in a Nighttime Treasure Hunt.These uv flashlights worked excellently to find the “treasure chests” that were spread out over about 2 acres of property.The effective range was about 25 feet away from the 7x4x2 white boxes.These uv flashlights recharged quickly each night and provided effective light for the duration of use each night - about 2.5 to 3 hours of use without loosing visibility.Purchased multiple different rechargeable uv flashlights that looked the same, but with a different label on them - end result, they were the same flashlights probably from the same manufacturer and worked exactly the same, though the price was different.Yes, I do recommend these uv flashlights.

We use these for hunting scorpions in the yard/house during the summer (the joys of living in the desert). These are WAY brighter than the cheap ones at the hardware store, and it’s super convenient to just plug them in to recharge them. The others we had took multiple AAA batteries in one of those cartridge things, and it was always a hassle to get the light to work properly. These are really bright (no scorpions going undetected!) and it has a telescoping narrow/focused or wide/diffused light that is very useful.

UPDATE:The company refunded my money for the 1 light that will no longer work so great customer service. Hopefully it was a fluke since they are nice and bright and although the inners are questionable the case is built very strong.Bought 2 but only was using one light. It was very bright while it worked.However, something in the circuitry died and now it won't turn on or charge. I was careful and followed the instructions on 1st charging it and unplugging it when it was done. (Never overnight)It was working fine and I charged probably after only 15 mins of use this last time. I went to turn it on and nothing.....so for the heck of it I try charging it and the light won't even turn on unless I start to unscrew the tail cap.I wouldn't have bought one let alone 2 if I'd have known this. My Amazon return window is gone so I will contact the company and see what they say and update it if anything happens.This light was treated great and used less than 30 mins in total I'd estimate. Very disappointed since it was so bright when it worked.

These come in handy for many applications , but I use them in my garden and the various sheds we have. We live in a heavily wooded area where there are many bark scorpions. They glow blue under the beam of these lights making them easy to see.

We live in the desert SW, moved to a different neighborhood, and have noticed some critters around the outside of our home. I have some older UV flashlights that use 3xAAA batteries. I was recently told there are scorpions in the neighborhood, which isn't a big surprise. So on a recent night I took the old UV flashlight outside and the scorpions glow remarkably, but the flashlight wasn't very bright, and I figured I didn't see lot of them even though they're there. So I bought a set of two of these 365nM lights, not expecting them to be much better. The old ones are probably closer to 400nM wavelength (they look more purple, whereas these look more sky blue when pointed at something white that does not fluoresce). WOW! We have lots of scorpions (the tiny, very deadly ones) in our backyard. These are MUCH brighter, and they fluoresce cotton and paper and other material much more than the old lights do. I wasn't just impressed, but amazed! They took a long time to charge (about 3-4 hours) when I first plugged them in to a 65W charger that supports QC, PD and a bunch of fast-charging protocols. They get a somewhat warm when left on for 5 minutes straight. But that just means that the LED is powerful.

These black lights rock! They rock so hard that you may have nightmares about what you find when you use them. Use this with caution, because you will never unsee what they may show you. It did help me find a spot that we had been searching for that we were smelling but couldn’t seem to find. It lit up like a Christmas tree and had us questioning how on earth he even was able to pee in the spot he did. I then made the mistake of taking it into my daughters bathroom. Her and I had to have a chat and I realized that I needed to use these things when I was cleaning because it shows… everything. They also make you realize that your pets are gross and while they may not be having accidents everywhere, they do track some nastiness around. I now walk around my house at night like a detective making notes of spots that need to be cleaned up that I can’t actually see without the black light. It’s amazing what a good black light and enzyme cleaners can do for the cleanliness of your house.

Two at this price is a steal! You will be able to find blue, dark rocks, extremely easy with these. They will light up any glow.The dark object brighter than you've ever seen before! They work so well you may want to save yourself a nightmare! Don't use them in a hotel room to look around before settle down! You'll wont to leave! If you're lucky you might like what you see I know you pick the right hotel! But do you want to take the risk? That's up to you. But these are good flashlights!

Bought a twin pack. One was defective & wouldn’t even charge. Returning them
