Fluorescent Light Sources

A fluorescent light source is a tube containing mercury vapor and lined with a phosphor. When current is passed through the vapor the strong ultraviolet emission excites the phosphor, which emits visible light. The ultraviolet itself cannot emerge because it is absorbed by the glass.
