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

Very versatile flashlight. Read the instructions. Bright light which I needed. Good price. Easy to carry.

One came scratched. Work well. But pay attention to which way the batteries are inserted. The wrong way won't work at all, but flip it and it works. Very bright.

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.

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.

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.

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 for 2 blacklight flashlights. I bought these to prove that my pooch was using my house as his personal latrine. Gross fact: dog pee glows under blacklight. I'm gifting one to my pet-loving friend. Bonus, I can use it on my antique dishes to see if they glow.

Para su presión es lo mejor que hay sirven muy bien luz potente dé noche

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