What Is a UV Flashlight?

A UV flashlight emits ultraviolet light, typically in the 365nm–395nm wavelength range, which causes certain materials to fluoresce. This makes invisible substances visible, making UV lights extremely useful for:

• Pet urine and stain detection

• Industrial leak detection (AC dye, automotive dye)

• Mineral and gemstone inspection

• Forensic evidence detection

• Currency and document verification

• Scorpion spotting

• Hotel room cleanliness checks

Among these, 365nm UV flashlights are considered the professional standard due to their stronger fluorescence response and reduced visible purple glow.
