LELUOHQ2 Pack UV Penlight Flashlight with Clip，Mini 395nm Mini Pen Light ，,Waterproof Ultraviolet Flashlight for Leak, Pet Urine, Scorpion, Hotel Inspection, Dry Stain and Bed Bug.

I wanted this flashlight to find out if our cat was making a mess outside her litter box. This flashlight is amazing for that, works exactly as I hoped it would. It lights up any stains or moisture. It also shows lint and hair so I could tell what parts of the carpet aren't getting vacuumed as well. Then I ended up on a terrifying scavenger hunt all through the house to see what needs cleaned better. I was horrified at some of the things this shows, but I can tell you my house has NEVER been cleaner. So this definitely works extremely well, but be careful because you CANNOT unsee the things this flashlight will show you. I had previously bought a blacklight from the pet store to help with cat urine and it didn't work at all, but THIS flashlight works almost too well. Highly recommend!

Slim size is like a marker so it is perfect for a pocket. Bright but not super bright but will definitely light up what you need in a close distance!!! Would recommend especially if looking for specific items you need to light up.

They do work. I just wished they were brighter.

This is a great UV flashlight. There is a tab over the battery that keeps it charged during shipping. The lithium battery is included. Also included is a USB C cable and wrist strap. Check out my photos of a toilet and sink that does not show these stains under normal light. Urine, vomit, feces residue and other biological stains do fluoresce, or glow, under ultraviolet light. Many cat owners use this to find where cat urine is on their floors to clean better. This is much brighter than any UV light I have seen in the past. This is also useful for US currency. modern $20 and $100 dollar bills have a vertical stripe on the left side that glows under a UV light. This is a very useful UV light and only costs $25.99. A very good deal.

If u travel like I do and stay in hotels and Air BNB’s this is something u need just as much as your toothbrush. This will keep u from unknowingly laying on a bed that hotel housekeepers might not even change the naked eye can’t see the gross stuff that can be on beds, sofas etc. Anytime u stay at places that are being used by millions of people if you’re not on top of stuff I speak of u need to be! Bed bugs is taking over stay over places a good hotel or Air BNB will have zipped protectors on the mattress and box spring (I pack those too lol) great great thing to have on beds but what about the sheets when u check in a place nobody really knows if the sheets been changed I use to be a housekeeper only 2 months in the 90’s as a teen not a job for me and trust me it’s some lazy people that do that type of job and will skip the sheets I was always the last one off cause I cleaned to slow and too detailed u only got so many minutes in each room and might have a whole floor by yourself what u think a lazy person will do skip steps in cleaning I seen it happen…With this item you can see stains on sheets, beds, walls etc even if u spray down a wall to clean it this light will show everywhere u sprayed and wiped can spots bed bugs bodily fluids and much more. So travelers keep your suitcases and bags off these hotel floors and never walk around barefoot on the carpets and check your beds cause we living in a different time that people dnt care about sanitation and hygiene and good work ethics. This light can be used to check for hidden cameras too! Be safe and clean travelers!
