6 Pack 395nm Mini UV LED Keychain Flashlight UV Keychain Light Black Light for Detections

Mini uv light good for on hand in case you ever need something uv sensitive. Simple to use, good quality. Button use is super simple.

Have had these for forever now and have not had to use more than the first one yet because it hasn't died yet. Very bright and very handy design, great for attaching to badge reel or key chain if not in the medical field

I use these at work now and I work for USPS. Youay not be aware of it but on the back of your letters on the bottom left there is a light orange ink called a ID tag. I work on the machinery that prints those tags. These tiny keychains are AWESOME to light up that ink! I bought several boxes of them and handed them out to everyone on my team. They absolutely LOVE them! Construction is great for the price and good quality. There is a guard to prevent accidental power on as well. Which is an awesome gesture considering they use CR2077 batteries which are quite small. What a great buy for the money. I was so happy to see their faces light up when I gave them to them. I'll prob buy more to give to other shifts.

The brightness is exactly what I wanted to help me see what I’m doing when operating a telescope or camera at night without blowing my or others’ night vision. The switch that lets you turn it on without having to squeeze it is a good idea but not well-executed; it’s very stiff and can’t be operated with one hand (and might crack your thumbnail)

Perfect for my keychain! Lightweight and bright.

I like to look for uranium glass at thrift stores and garage sales. These little lights are very powerful for their size, and provide more than enough power to test pieces for that iconic green glow. I don’t have to bring my bigger flashlight around anymore and will never forget it at home because it’s now on my key ring. Perfect!

Works as advertised however the switch is terrible and difficult to activate.

I bought these because I wanted a small light to attach to my car key to light up the ignition cylinder in the dark, and wow did these deliver! Since they are flat on the backside, I just used a 3M adhesive sticker and good to go. Light is super bright and replaceable batteries as well. Can't beat the price either!

Muchas gracias, muy prácticas

Perfect for any application where you need a red LED with momentary or on/off switch. I bought these for the tripod of a telescope. This pack will do two scopes. Works great.

Awesome little lights

Work well. Nice to have on a keychain for uranium class hunting

It's a good light that fits my purposes. Just to light up my bag. I do wish the on position was the other direction but whatever.
