10 packs UV Mini Keychain LED Flashlight Torch Light Lamp, Blacklight Key Ring Light Torch, Black Light UV Flashlight UV Light, Ultraviolet Urine Detector for Dog,Batteries Included

Barely bright enough to light a key.

They aren’t super bright in normal lighting but that’s ok! I sell uranium glass in my oddities shop and I wanted to offer black lights people can buy with the uranium glass they take home if they don’t have one. In daylight they aren’t super strong but in the dark they work perfect and you can still see the glow up close no matter the room lighting.

We used these for an escape room party to find some black light writing and these were great! Bright light, worked with liquid laundry detergent being the material to find, and the kids had a blast with them! The keychain is a fun bonus! Also, they have a button to turn them on permanently or your can press down for little bursts of light. Love these!

Received the order on time...Because I had had some failures with another vendor''s lights, - I tested every light - Found NONE of them with dead or extremely low level batteries. That's great. - And besides, in the event that they die later, they're made with screws - I can take them apart and replace batteries and re-assemble. Perfect! - But: as I said... no need yet... ALL WORKED GREAT!

I have a UV art installation as seen in the picture, it’s at an annual music festival And I’ll be pairing these awesome little guys with some $1 key chain laser pointers for people to take home 👍Also these are great for people that are shopping for UV reactive items (paint/ink etc...) because it’s on your key chain already!

Used this for hidden messages for a game - great for the price - light weight, easy to use, and easy to hide. Happy about the quantity since the first one I tested only worked for about 15 seconds. Glad there was enough I could use the others as back ups.

I give these away when I do a uv tattoo so clients can show them off. They are bright, last a long time, portable and affordable. It also has a tiny switch to keep it on for short periods.

The item itself is great minus one aspect. I work nightlife security and wanted to use this for flagging false i.d's. Sadly this product only picks up a portion of the uv ovd's on id's. Example is on the new California's, this product picks up the uv ghost image, but does not pick up the uv ovd which involves the birthday on the i.d., and some other images like the Coit Tower. Nice for everything but i.d. checking. Small, easy to use...just don't get it if you're a doorman.
