What is the difference between Fluorescent and incandescent lamps ?
Incandescent Lamps: Regular incandescent lamps produce light by passing an electric current through a filament in a vacuum or gas filled bulb. They provide low initial cost, good color rendition and excellent optical control. Halogen Lamps: Halogen lamps also use a filament; but since it is sealed in a pressurized capsule containing halogen gas , the lamp provides brighter, whiter light and improved energy efficiency. Linear Fluorescent Lamps: In a fluorescent lamp, an electric arc passing between cathodes in a tube excites mercury vapor and other gases and produces UV radiant energy. A phosphor coating on the tube then converts this energy to visible light. Fluorescent lamps are very energy efficient and provide a wide range of color responses. Compact Fluorescent Lamps: Compact fluorescent lamps employ small diameter tubes that are bent so they begin and end in a ceramic base. This allows them to be produced in a wide variety of configurations, greatly extending the applications for
