Alonefire SV62 Mini 3W UV Flashlight 365nm Portable Ultraviolet Black Light Very Small EDC for Minerals, Pet Urine Detector, Scorpions, Finding Stains, Money Detection with AAA Battery Easy to Replace

This is a nice compact UV pen - only takes one AAA battery. I wanted something on the small size. I used this to show UV printing and reactive rocks and minerals Seems to be decent quality for the money so I feel it was worth the price

Nice little 365nm uv light. Alonefire sv62 3 watt. Great for checking florescent item's at yard sales, thrift shops, auction's etc. Works great and easy on battery life. It has a black filter lens which is standard on better quality UV light's! Would recommend.

It functions well, and in an appropriately dim environment lights up a decently sized area.

Nice compact design and good quality and works great. Wish they made a white LED version of this flashlight!!!!

This is a true 365nm UV light at a great price! Has the blueish UV light that reveals EVERYTHING, compared to the purple light of 395nm UV lights. Tiny! Light weight! Uses a single AAA battery. Test it out in your bathroom with the lights out - if you dare :)

The ALONEFIRE SV62 Mini 3W UV Flashlight is a handy size and takes a normal AAA battery for easy replacement. The beam reaches across an office or residential room easily. This form factor is easy to carry in a shirt or pants pocket, and the button on the tail cap gives a positive on and off so it doesn't shine in your pocket accidentally. I also like the purple lens housing so I can spot the UV light easily among my other flashlights.

This is not a good rock hounding light. It is 365nm but simply not bright enough to be effective when being held at adult or kids height.

I've tested multiple UV Flashlights.... If you are hesitant on purchasing this, don't be. I promise you will be happy you did.
