UV Flashlight — 395nm Ultraviolet Torch, 51 LED

Ultraviolet light reveals what ordinary light cannot see — fluorescent minerals, counterfeit bills, scorpion tracks, hidden biological residue.

At 395nm, this falls just below the human visible range where fluorescence is brightest. Minerals containing fluorite, calcite, and scheelite glow with striking colours. UV inspection is used in NDT (non-destructive testing) to find cracks, in forensics, and in geology fieldwork.

• Wavelength: 395nm | 51 LED array
• Runtime: ~4 hours on 3×AAA batteries (included)
• Waterproof housing | Wrist strap
• Compact: 14cm length, 100g
