COSOOS 2 Pack UV Flashlight 12 LED Handheld Blacklight Flashlight 395nm Mini Light Torch Detector for Dog Pet

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. Read more

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. Read more

The caddy for the batteries was upside down in my flashlight, and worked once I flipped it around. It's not a powerful uv but works well enough. Read more

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!

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 Read more

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. Read more

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. Read more

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! Read more
