UV Flashlights (Ultraviolet)
Ultraviolet UV flashlights are useful in leak detection, forensics, pest control, HVAC, authenticated money and documents and more. UV light will cause things to fluoresce. UV output is measured in nanometers or nm and the output specification usually ranges from 365 to 400 nm. A higher number designates more visible light. Most UV flashlights work best in low light conditions, and you normally have about a 1 to 3 foot range.
