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

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

I bought this to review hotel rooms (I frequently travel) to make sure I got clean sheets. However, most cotton sheets illuminate equally. I've seen one or two that have a yellow (under the blacklight) covered pillowcases, but those have been at my parent's guestroom (so it's undoubtedly my drool, not a stranger's) and but what it's mostly good at it spotting less than clean carpet, sinks, and showers. It does work very well for that, though. The problem is that even under the black light, it takes quite a bit of scrubbing (which suggests the hotel staffs haven't been slacking, just that it took more than they understood). So unless I want to bring scrub gloves and a whole cleaning kit, the amount of grime I've seen is acceptable. Except the carpets. Ew. Nothing to do about that, though.

This light does exactly what it's supposed to do. The black light feature works great!

Good Price its Not too Bright but will do the job,

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!!

Great little light. It doesn’t even have to be very dark to find urine spots. I would buy this again in a heartbeat.
