LIGHTFE Black Light 365nm UV Flashlight UV101D with High Power UV LED Source Keychain Light Powered by 1 AAA Battery for UV Glue Curing Light, Pet Urine Detector Light, AC Leak Detector…

It fits right in that weird little small pocket in my jeans so that I can easily grab it when looking for certain types of glass at thrift stores, which it lights up brilliantly, by the way! It's a twist to turn on so it's nice that I don't make mysterious clicking noises. I can hide it in under my fingers and activate it one handed so I can be more stealthy. (I don't want everyone in on my glass finding game or asking me a bunch of questions!) It is pretty bright with a fresh battery, but it gets dimmer. It's almost too bright to be stealthy at first. I use rechargeable AAAs with it. It has helped me find a bunch of neat glass pieces and some other substances that I'm not as thrilled to find, but it's nice to know that they're there I suppose.

This is a very cool little, and I do mean little, UV light. It is unfiltered, so there is a lot of extra visible light, but the UV is truly 365 nm and it gets a good response from fluorescent minerals. It is powered by a single AAA battery, so it obviously is not as bright nor will last as long as a UV light using the same LG LED but powered by an 18650 battery. It isn't much bigger than an AAA battery either, so it is easy to take everywhere.

I am an auto glass technician, I bought this because windshield repairs use a resin that is Cured with UV light. Sometimes if I am in the shade or garage doing a repair and don’t have sunlight this is very much required. Most Uv lights for chip repair are 100-200$!! Which is outrageous. I bought this to see if it would work and honestly thought it would be a lot bigger than it was, so after I inboxed it I had high doubts it would work. However, this thing is powerful enough to cure the resin in seconds! I’ve used lights specified for windshield repair that took 30+ seconds and this one takes about 3

I was looking for a 365 to check glass while I am out and this is perfect! It seems to be high quality but it's new so I can't attest for longevity. I'm very happy with this light.

Very good for its size and price. Great wavelength. Even dealers at the mineral show were impressed. Sure, there are more powerful ones, but this one is great for a keychain size.

This little light works like a charm to help recharge the glow strips on my cane. And I can keep it attached to my cane strap for convenience.

I never got to see how this flashlight worked as I used the original battery and new ones and the flashlight would never work. And I even got a replacement and that didn’t work! Very disappointed as it was supposed to be a gift. Piece of junk!!

This light is perfect for spotting fake money on the go as I need to at work. Small size is perfect for me. One warning though, the key ring that attaches to the unit is brittle and will break over time. I highly suggest you purchase a better $1 metal ring for LIFETIME usage.
