Constant | Description |
COMPACTFLUORESCENT | A fluorescent lamp having a compact form factor produced by shaping the tube. |
FLUORESCENT | A typically tubular discharge lamp in which most of the light is emitted by one or several layers of phosphors excited by ultraviolet radiation from the discharge. |
HALOGEN | An incandescent lamp in which a tungsten filament is sealed into a compact transport envelope filled with an inert gas and a small amount of halogen such as iodine or bromine. |
HIGHPRESSUREMERCURY | A discharge lamp in which most of the light is emitted by exciting mercury at high pressure. |
HIGHPRESSURESODIUM | A discharge lamp in which most of the light is emitted by exciting sodium at high pressure. |
LED | A solid state lamp that uses light-emitting diodes as the source of light. |
METALHALIDE | A discharge lamp in which most of the light is emitted by exciting a metal halide. |
OLED | A solid state lamp that uses light-emitting diodes as the source of light whose emissive electroluminescent layer is composed of a film of organic compounds. |
TUNGSTENFILAMENT | A lamp that emits light by passing an electrical current through a tungsten wire filament in a near vacuum. |
