Cold Cathode Fluorescent Lamp (CCFL) and UV Lights are light sources that use a mercury vapor to emit UV light that causes a phosphor coating to emit light (CCFL) and other light sources that provide wavelengths in the Ultraviolet frequency range (750 THz to 30,000 THz). The CCFL and UV lights come in sizes from 2.0 mm to 11 mm wide and 25 mm to 600 mm long.
