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

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.

I just received my UV Light and examined my whole place!! I’m very glad I got the 51 LED Light, it works great!! I was even able to examine the ceilings. I highly recommend using this light to double check the quality of any work that you hire to be done on your home. I could see were the painters didn’t bother to paint.It also gave me a sense of comfort because I was expecting things to be worse than they were. I highly recommend that you use this to know what is and what isn’t clean.

The media could not be loaded. Buena potencia con baterías nuevas, se tiene una visión diferente de los colores, es necesario un reactivo para ver bien los residuos.

I work in the medical field, and I got these to ensure that some of the workspaces we have are clean, since we have to work with bodily fluids. I just turned the lights off, and used the flash light, and found any gross spots and got to clean them. This is super helpful to make sure we don't cross-contaminate clean with dirty.

My cat has a UTI and has been peeing outside the litterbox. I wanted to see where so I bought this flashlight. Not only did I find where she has been going, I found every place my cats have thrown up also. I have cleaned those areas, but apparently it never goes away lol. It showed where food/drink had been spilled in my dining room (that my kids never told me about.) It shows so much more that isn't apropriate to share in a public forum ;) Anything biological or food related, you will see it. The light works well. Too well LOL!

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!!

This is a fantastic flashlight I bought this cuz I got a stone from the Upper Peninsula and it lights up under black light and I wanted to try it but believe me I was not really prepared for what I did see in my apartment when the lights are off this thing shows you everything and anything and I was quite disturbed by what I saw so now I'm abruptly scrubbing my apartment down so like I said it is a fantastic black light flashlight but people be prepared for what you will see that you don't want to see

I got this to check for pet accidents. I can tell you, if you think your house is clean don't use one of these because you will see that you probably are not as clean as you think. Or do use it and then go on a sanitizing rampage like I did.Also as a side note I tried using it to find a centipede that terrorized me once night by running over my foot in the kitchen. I pulled a 1950s house wife and jumped up on a chair and lost the little terror and spent the next 30 minutes searching for it with this light. Couldn't find it and was about to give up when it came wriggling right by me yet again. I killed it then shone the light on it just out of curiosity. Did not light up at all. This light isn't advertised to show centipedes so I'm not complaining I guess? but black lights supposedly should light them up so I found it a bit odd and just wanted to throw it out there.
