Black Light UV Flashlight, 365NM Rechargeable Flashlights with Filtered 4 LED, High Power for pet Urine Detection, Resin Curing, Scorpions, Rocks, Car Leaks

We used this to look for Yooper Lights! Let me tell you what! These are some of the best lights for the novice rock hunter on Amazon. BE SURE to wear the UV safety glasses to protect your eyes! The light is very durable and comes with a special well designed case. It held charge wonderfully and were SO fun to use in the proper locations and back at the campground where we found more tiny ones in the rocks near the campsite! The zone to view the UV rays is focused so don't expect a larger wide angle. That focused view really ensures keep your sights set in a prescribed place too so that is helpful. These will likely go with us on many vacations to come. At home, post trip, these highlight tons of areas for improvement in cleaning. 😂🤣 It picks up everything (even the tiniest piece of lint and illuminates it for you!) I work with a lot of fabric in my free time... so imagine the stories this light tells when it illuminates that room even after a fresh vacuum. 🤪

Wide UV light allows for easier inspection. Haven’t had to charge as often as others.

My wife is a rock hound, as am I to a lesser extent. This flashlight has opened up a whole 'nuther world in that regard, and our grandkids LOVE to use it to view our fledgling collection of UV-reactive rocks. The 365 nm frequency is a great place to start when it comes to UV lights for hobbyists, and the black filter adds to the overall effect by cutting the visible light coming emitted by the LED's. I saw one complaint about the "cheap" charger, but I have found it serves its function just fine.

The flashlight works great. The charger is garbage. If you buy the flashlight be sure to purchase a different charger. The charger that comes with it doesnt charge completely and you can't tell if it's charging or not.
