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.
LED Lamps: Light from LEDs is concentrated in a beam. Refractive lenses are used to diffuse and spread the beam but this dramatically reduces light output. They are a good choice if mounted close to the work surface. LED’s are not recommended for lighting large areas where a wide dispersal of light is needed. Fluorescent fixtures are the most efficient source of light for illuminating a large area.
Linear Fluorescent Lamps: Are 4-5 times more efficient than Halogen or Incandescent 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 fluorescent lighting.
