2FT 18 Watt Blacklight(UV) T8 Fluorescent Lamp

A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. Fluorescent lamps come in many shapes and sizes. Many compact fluorescent lamps integrate the auxiliary electronics into the base of the lamp, allowing them to fit into a regular light bulb socket. Typically a fluorescent lamp will last 10 to 20 times as long as an equivalent incandescent lamp when operated several hours at a time. Under standard test conditions fluorescent lamps last 6,000 to 90,000 hours (2 to 31 years at 8 hours per day). *Requries Ballast*

The ultraviolet lamp usually consists of an electric discharge lamp with material that yields radiations at the desired wavelength. Ultraviolet lamps are usually housed in quartz or special glass that transmits ultraviolet radiation more readily than ordinary glass.
