MIU COLOR Black Light UV Flashlight, Small UV Blacklight with 21 LEDs, 395nm, Compact Handheld UV Flashlight for Dogs Urine Detector and Scorpion Hunting

This light is strong enough to illuminate cat urine spots even in the day light. Just beware, it highlights EVERYTHING, and lit up my carpet like a Dalmatian. It’s definitely strong enough and a great tool to identify areas that need to be cleaned more thoroughly.

Very weak light. Only good for checking hand held things like currency notes or documents. Not suitable beyond two feet.

Worked perfectly for my big project and can’t wait to use it for future projects.

This is a compact black light flashlight that's easy to use and carry.

I have the 51 LED black light from this company and wanted to buy a smaller more pocket/purse friendly size for my daughter since she works at a restaurant and deals with fake ID’s and large money bills.Batteries didn’t come with either flashlights. The 51LED of mine works fine for what I needed for my rocks and stones and to see pet accidents. I got her new light in the mail today and compared the two and I will be sending hers back to buy another. Her 21 LED Light was smaller in size with less LED lights but… I wouldn’t even consider it to be a UV light in my opinion! You can see a drastic difference between the two in my photos. Just terrible. It wouldn’t pick up stains on the carpet that I knew were there from my brighter 51 LED flashlight. This company’s larger 51 LED seems fine but don’t buy the smaller 21 LED if you plan on actually using it for something. Very disappointed!!
