Incandescent Lamp |
Light source that produces light by heating a filament until it glows. |
PAR Lamp |
Parabolic Aluminized Reflector Lamp. A precision‐pressed glass reflector lamp which can use a variety of technologies including incandescent, halogen, or HID. |
Halogen Lamp |
Type of incandescent lamp that incorporates halogen in order to increase the average life and light output of the light source. |
Light Emitting Diode (LED) |
A semiconductor device that emits light as electrical current passes through it. Light‐emitting diodes are more efficient than other light sources and offer exceptionally long life. |
Fluorescent Lamp |
Low‐Pressure Mercury‐Vapor‐Gas‐Discharge Lamp that uses fluorescence to produce visible light. Fluorescent lamps require a ballast for current and voltage regulation. |
High‐Intensity Discharge Lamp |
HID Lamps. The family of electrical gas‐discharge lamps that produce light by means of an electrical arc. |
High‐Pressure Sodium Lamp (HPS) |
Type of High‐Intensity Discharge Lamp. Frequently used in street and outdoor lighting applications. |
Mercury Vapor Lamp |
High‐intensity discharge lamp that generates light by passing an electric arc through vaporized mercury. |
Metal Halide Lamp |
High‐intensity discharge lamp that generates light by passing an electric arc through a mixture of mercury and metal halide gases. |
