Benefit from the energy-saving and long-lasting properties of fluorescent lighting. This popular technology generates light by running an electric current through a tube filled with mercury-vapor gas. Some fixtures come with added protection by means of tube guards for fluorescent lights that can slide over the linear tube light to protect it or even to change the color of the light. Fluorescent bulbs come in different shapes, most commonly linear fluorescent lamps, circular fluorescent lamps or compact fluorescent lamps. Some popular models include T4 twin tubes, T12 or T8 bulbs, commonly used in commercial applications. T8 light bulbs also come as U-bend or shatter-proof fluorescent tubes for added versatility of applications.
