LE Small UV Flashlight, Portable Black Light with 9 LEDs, 395nm, Ultraviolet Light Detector for Invisible Ink Pens, Pet Dog Cat Urine Stain and more, AAA Batteries Included, Pack of 2

Its a black light, I use it for my scorpion. Works great.

Great

This LE 9-LED UV Torch is a compact and handy little blacklight that performs well for its size. The 395 nm LEDs produce a strong enough UV glow to easily cure small resin prints and make fluorescent materials stand out. I’ve used it for quick resin curing touch-ups and checking UV-sensitive items, and it’s worked reliably each time. It feels solid in the hand and the portable size makes it easy to carry in a pocket or tool bag. The beam is narrow and focused, which works well for detail work but isn’t ideal if you need wide-area coverage. Battery life is decent for occasional use, though frequent long runs drain it faster than expected. Overall: A practical and affordable mini UV light — great for resin hobbyists and small-area blacklight needs. Not powerful enough for large surfaces, but very useful as a compact tool.

I used these Black UV Flash Light for Hunting Golf Balls and they worked perfectly. When hit with a UV flashlight, they glow brightly and are incredibly easy to find—even in tall grass or rough terrain.

Happy with this product
