DARKBEAM UV Flashlight 365nm Black Light, Mini & Powerful Woods Lamp USB -C LED Rechargeable, Blacklight Flashlights Portable Pet Cat Urine Detector - Rock, Fluorescent Detection, Resin Curing

This light works TOO WELL. I got it in order to find out where else my cat may have peed and not only did I find out, I found probably 200 years of god knows what. I live in a 200 year old converted house and there are things on my walls that are probably older than I am. It also works crazy well for finding lint, as it turns out. I bet you didn't know that even if your painted walls look uniform in color...they aren't. Or that you could find out whether tobacco smokers have smoked in a place using a black light. I got a second hand couch and it looks clean, but I'm sure you can guess what I found. Dont' get me started on my visually spotless toilet and sink :( One of my sheets had splotches on it despite being clean and having no odour so I guess if there's some invisible damage or change made to your fabric items, you'll be able to see it with a blacklight.Anyway, it works really well. It's bright, or whatever you call it. Stuff shows up extremely well. It has a nice weight to it and doesn't feel cheap. The packaging was straight to the point and included a charging cable and a wrist strap (so that you don't accidentally throw it at somebody when you gesture in shock at what you find, surely).It worked out of the box but I'm charging it up now so I can traumatize myself some more and check my work after a Deep Deep Cleaning this weekend.I guess that could be a potential downside. You might night want to touch anything in your home ever again if you look at it with a blacklight.

This is the one! I bought a different black-light flashlight to find pee stains from my not-quite-potty trained puppy. They were hard to spot. Whatever frequency/wavelength whatever this one is - it’s perfect. They show up great. It’s small, it’s super bright, it’s rechargeable.If you are buying a blacklight to find pee stains - this is the right one!

It works like a champ on the uv resin I use. But dear God, don’t go looking around your bedroom or even worse your kid's room with it.

Great flashlight for the price; just be warned that it will not charge if the power source is too powerful (a lot of modern chargers won't work).

Works great for detecting stains in hotel rooms!

It's lit, durable, functional. battery life must be a beast cause i didn't even know it wasn't fully charged when i first got it. today I charged it up and was super surprised. Be careful what you look at you can't un-see it.

I bought this to identify ringworm on my foster cats and this works so well. It is very strong and can also be used for looking for any cat urine on surfaces. I like that it is rechargeable and think the materials are high quality.

I bought this black light specifically because it is advertised as having 365nm UV light instead of the more common 395nm. From everything I've read, for cat urine specifically, you need a blacklight in the 365 nm to 385 nm range in order for it to show. I already had a 395nm blacklight, so I bought this one specially to help me quickly find spots left from my kitty, who has crystals and sometimes goes outside the box. This unfortunately DOES NOT WORK FOR CAT URINE. I am so disappointed. It works amazingly for anything else, the bathrooms were lit up, and I was very grossed out by that. I know for sure it doesn't work for cat pee, though, as there were two specific spots where my cat went, and neither showed at all with the blacklight.
