DARKBEAM UV Flashlight 365nm Black Light, 3 LED Ultraviolet Flashlights 20W Powerful Woods Lamps, USB-C Rechargeable UV Light - for Pet Urine Detection, Money, AC Sistem, Blood Tracking, Resin Curing

３６５nm、20w、保護カバー、保護メガネ、ストラップなど色々付いて価格も手頃なので最初のUVライトとしてオススメかと思います。 しっかり、蛍石が判別できました。 21700充電池なので持続も良いです、 UVライトは熱くなる物なので時間を空けつつ使用して下さい。

I bought this to charge glow in the dark discs for disc golf, it's super powerful and does an amazing job. Unfortunately I shone it in my house with the lights off ...I then spent an hour scrubbing walls because my house looked like a crime scene. The flashlight does almost too good of a job.

I use this to charge the lume on my watches before I go to sleep. It charges them very quickly, in just a few seconds, and lets them shine bright throughout the night so I can always tell the time. I've charged it once about 2 months ago and it still is in the green for battery. I like that the power button LED changes when it's low on power.

意外と紫外線が強かったです。照射した物体からの反射光が眩しいので気をつけてください。いろいろ使えて便利です。ライトの代わりにもなりますが、バッテリーの消費が早いので気をつけてください。

Powerfull beam, very efficient with my UV blue. The lens are effective against UV light.
