I'm pretty sure I left my old 395nm in an antique mall, so I had to get a new one. Saw this big ol' boy. 21700 battery, USB C rechargeable, and it has both 365nm and 395nm wavelengths.

VERY powerful, especially for single emitters. It does get warm but not blazing hot.

It's also a "zoomie" so you can focus the light to hit a piece far away. Great for when something is behind a counter or otherwise out of reach.

Highly recommend this one.
