## Description

desertcart.com: ULTRAFIRE 502UV 395-405 nm Black Light UV Flashlight Zoomable | Super Power Blacklight Flashlights for Leak Detector, Pet Urine Stain, Bed Bug (Not Included Batteries) : Sports & Outdoors

Review: Reveals Some Scary Stuff - Works as described. Amazing what you can uncover snooping around the house.
Review: Better than expected for the price. Uses 18650. Focusable. - Very nice for the price. I've been using a pocket UV flashlight powered by 3xAAA for the longest time for lures and circuit board work. Recently I changed to a different resin and that old flashlight just takes forever and burns through batteries like crazy. (AAA flashlight on left, this ultrafire on the right in photos) Was looking for an 18650 or 21700 powered flashlight since I have such batteries readily available. This thing kicks. Far more powerful and it has a focusable lens which is superb for when I only need to cure in a small area. It has no charging circuit. So you will need a way to charge your 18650 outside the device. Very solid construction. Pleasantly surprised. The clip is secured with screws not a tension ring. Total game changer. Never have to worry the flashlight escaped the clip. Size is nice imo. Good hand fit for holding normally. Little awkward if you want to hold it like a penlight though because it's back heavy. Only con: no lanyard/ring hole I would buy more of these for ice fishing (jigging glow in the dark lures) but without a way to secure it to my person I might have to pass. There are holes in the clip if you wanted to tie on there but then it gets funky not hanging straight.

## 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.
