Review: Nice and bright - This worked great for detecting freon leaks in an automotive A/C system. It’s perfect for spotting those little things that regular lights just can’t pick up, like pet stains or hidden markings. It has great power with its UV 395-405 nm LED. The beam is strong and covers a good area, making it super handy for all kinds of tasks. Plus, it feels solid and well-made. If you need a high-quality UV flashlight that does the job right, this one’s definitely worth checking out!
Review: It's good, small and bright. - I bought this flashlight for uranium glass shopping. Testing it on the uranium glass I already have, it works as expected. I took it paint shopping recently too. I was looking for what paints are UV reactive, to spice up some things I'm planning on making. The added bonus is that it charged up the glow-in-the-dark paints too. It's nice being able to test paints in the store, especially with this compact size. My older lights were much larger, and more cumbersome to carry into stores discretely. It takes a standard 18650 battery. We have a bunch for other lights and assorted stuff. 18650s are the new standard for portable devices, replacing AA/AAA batteries that would just die off fast.

## Questions & Answers

**Q: Will this light dry and harden UV glues, like those used in fly tying?**
A: Works great for the "Damn Good" brand UV glue.  I used it to fix a broken pair of glasses.  The frame around one lens had broken, and I couldn't get new frames for the existing lenses.  Just made the mend last night.  I'm not certain how long an exposure ti takes--I gave it about 2 minutes.  The glue's surface was still a little soft,  but an hour later it was completely hard.   Quite a bright light and I would be careful not to expose your skin or eyes to the beam.  I will use it for fly tying as well and expect it will work very well.

**Q: how long to completely cure and what brand of uv resin has anyone used with this light?**
A: works great with loon, solraez, gulff probably the fastest. Average cure 10-20 seconds is my estimate, get a good 18650 battery though.

**Q: One part of the description indicates it operates up to the 405 nm another says only up to 395 which is it?**
A: There is 2 available nm that I know of. 365 and 395. 395 has a more purple more intense beam. Better for resins and glow stuff. 365 has a less visible beam better for seeing uv marks or ink doesn’t work as well for drying resin or charging glow in the dark stuff

**Q: I have two cr123 batteries which way do they go in? It says use cr123 batteries... then how do they go in??**
A: + goes in first

### ⭐⭐⭐⭐ Strong, effective black light—just be ready for the unusual battery
*by M***E on August 3, 2025*

This is a powerful UV flashlight that really does its job well. Whether you’re checking for pet stains, leaks, or other hidden messes, the beam is strong and clear, and it reveals details even in well-lit areas. The one thing to note: it requires a 18650 rechargeable battery, which isn’t something most people have lying around. You’ll likely need to order it separately, and it’s not included with the flashlight. Still, excellent performance overall—just be sure to have the right power source ready to go.
