COSOOS Black Light Flashlight, 2 Pack 12LED 395nm UV Handheld Black Light, Mini Torch Light, Dogs Urine Detector for Dry Urine Stains, Bed Bugs and Scorpions.

I bought this black light after struggling to clean an oriental rug when someone let their dog go wild. Regular cleaning wasn’t solving the problem, so I needed a way to track down the root cause. This little tool worked perfectly. It’s very easy to use — just slip in 3 AAA batteries and it’s ready to go. The light quality is strong and clear, making it simple to spot hidden stains that would otherwise be invisible. Within minutes, I was able to locate the source of the odor and treat the rug properly. The difference was night and day, and now the rug looks and smells so much better. For the price, this black light is an excellent value. Whether you’re dealing with pets, spills, or other mystery messes, it’s a great product to have on hand. TL;DR: Compact, easy-to-use black light that makes hidden stains visible. Saved my rug and made cleanup simple.

Works so good! Small and compact but bright

These lights are very handy for disc golf glow events. We used these to charge up our discs and they worked great. Played 24 holes and the batteries made it through with no problems lights feel okay, maybe a little cheap, but the light weight is good when you’re lugging them around the course. The light output is sufficient to easily charge up your disc if you keep the light close to the disc. Overall, it’s a good product that serves the purpose and isn’t too heavy.

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

I have been using this a lot more than I thought I would! So a friend of mine in the plant community told me to get a black light flashlight to help spot pests on plants because they will glow when you shine the light on them. I did have a pest (thrips) but I was currently treating them so I used the black light flashlight to determine if I needed to repeat spraying. Although I am using systemic granules, I figured there were some at a different cycle in the lifespan so it would be immensely helpful to check them with the use of this flash light. They come in a 4 pack which is great because I gave two to my daughter since she has indoor houseplants as well. These compact flashlights provide adequate light, perfect to store or even fit in your purse if traveling. Highly recommend!

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.

These UV flashlights are powerful for their size and work great for detecting stains, pet spots, and more. The build feels solid and the light is strong and clear. Getting two in a pack is an amazing value.

I got these for my little daughter so we can light up the stars in her room. It's a good solid product. So far it's working and the battery life hasn't disappointed.

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