This compact 365nm UV mini flashlight is the perfect add-on for rock and mineral collectors—especially for stones like Yooperlite and other UV-reactive finds. Unlike many common UV lights sold online (often 395nm), 365nm typically produces a stronger, truer fluorescence in minerals, so colors pop more clearly when you’re checking a piece at home or on the go. Built from solid black metal with a premium feel, it’s USB‑C rechargeable (cable included: USB‑C to USB‑A) and comes with a short lanyard cord for easy carrying.
