COSOOS 2 Pack UV Flashlight, 12 LED Handheld Blacklight Flashlight 395nm Mini Light Torch Detector for Dog Pet Urine Stains, Bed Bugs and Scorpions. (Batteries not Included)

This COSOOS 2-pack UV flashlight set has been incredibly useful for multiple applications. The 12 LEDs put out strong UV light that really works—I've used them for finding scorpions while camping, detecting pet stains, checking for leaks with UV dye, and verifying currency. They perform way better than I expected for the price. The build quality is solid with durable aluminum construction that feels substantial in hand. They're compact enough to carry easily but large enough to be comfortable to hold and use. The battery compartment is secure and the on/off button is responsive. Having two in the pack is perfect—one for the house and one for the camper, or one for me and one for backup. The UV output is consistent across both lights with no dead LEDs or weak spots. Battery life has been good with standard AAA batteries. These lights have proven their worth countless times. Whether for practical applications like leak detection or just fun uses like seeing scorpions glow at night in the desert, they deliver strong UV output reliably. For the money, you really can't beat this set. Quality UV flashlights at a fraction of what single units cost elsewhere. Highly recommend

Only use them for a couple of days but seem to work well and good quality. I put batteries in all four and all four work very well.

I would give these a 5 star, but the only thing holding me back is the heftiness of the flashlight itself. More like 4.8 stars if I could. It's great, don't get me wrong, works perfectly, used it on identifying some uranium glass and some minerals in some rock samples as well. It is 100% a working UV light, and what's more is there's TWO flashlights included! The flashlights themselves seem sturdy, but not overly sturdy like some of the other stuff I've even gotten at Walmart has been. The metal feels fine, totally useable, but just ever so slightly thin, somehow. Like if dropped on the rocks too many times or gotten around a few to many splashes might damage or weaken it where as a thicker metal housing would add a sense of weight and toolness to it. Like a maglite almost. Good price for what it is though. Beam isn't as strong as a regular flashlight even, this is meant for close up, convenient, handheld observation, just perhaps not out in the field. Uses 3 AAA batteries. I would recommend this if you want a cheap simple UV flashlight to use around the home, that comes with a second one.

First, let me start out by saying the customer service is excellent. When I received these, one flashlight had some LEDs that didn't work so I was super bummed. Currently I have no transportation so getting around to return them would have been an issue. So I contacted the seller to see if there was any other way to fix the issue. Honestly, I was just hoping to be sent a package with postage paid so that I could send it back and have it replaced. The seller sent me a whole new one without issue and it works perfectly fine it! It was very quickly replaced and I'm super excited! Now for how it works. These are super bright to be so little and they work awesomely. I was able to see hard water spots on every surface it appeared and stains in my carpet that I wasn't even aware of. I was able to see spots that I had missed, cleaning around the toilet. It works perfectly. It even works better than and is much more lightweight than the more expensive one I was replacing it for! An added bonus is that because its a UV light, it makes my glow in the dark tv remote covers glow brighter and longer than they ever have. I have issues seeing things in the dark because they sort of blend in. So it's now easier to see them in the dark than it was before. In closing, I would definitely recommend these flashlights and if there is any issue it will be handled because like said, the customer service was excellent and there was no hassle what so ever. Another added bonus, you can't beat the price. I paid less for two of these than I did for my old one which was around $8 more and had less LEDs. So I'm definitely satisfied with my purchase!

Perfect size. It has a really good strong lamp. And they worked wonderfully for the purpose I bought it for! And I was able to share one.

Great price too bad they’re not very bright at all! I guess you get what you pay for I at least expected a better beam of light. I got it for checking for hornworms on my tomatoes in the dark. And it barely lights anything up. Disappointing, if I have time, I may still return them. I don’t see how they would be useful for much of anything, they have the little looks like spread out bulbs in the circle, not a nice beam of a light. Keep that in mind for whatever you’re looking for a black light flashlight for. I knew what they look like. I just expected a stronger beam, they’re extremely weak. It’s not that they’re not quality on how they’re made or how they look, they are just not bright enough at all. I use them in the dark on the plants and they barely lit anything up at all. The hornworms glow kind of, so they’re easier to find with a black light. Too bad they didn’t work for me for my purpose.

Great little UV flashlight. I ordered these to help find Yooperlight rocks. Can’t wait to go out and find these beautiful rocks that were discovered in 2017. There’s a picture of the rocket itself and then a picture of the rock with this UV flashlight. Have fun rock hounding. Well I tried to take a picture of the rock with a light, but it doesn’t do it justice. You’ll have to try it for yourself.

I used this UV flashlight on my cat after noticing some bald patches and being concerned about possible ringworm. In a veterinary exam room, we turned off the lights and used the flashlight to check the affected areas. The light was bright enough to clearly see whether any fluorescence was present. In this case, there were no glowing areas, which helped the vet rule out ringworm quickly and painlessly—no bloodwork needed at that stage. The flashlight was simple to use, lightweight, and easy to handle. The 2-pack was a nice bonus, and I even gifted the second one to my vet tech as a small thank-you for her help and care. Overall, this is a very useful tool to have on hand for quick visual checks in low-light conditions. It worked exactly as expected.

Cheap uv flashlight for charging up glow-in-the-dark resins and fishing lures. Does the job.
