Enumeration definition

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.
USERDEFINED	User-defined type.
NOTDEFINED	Undefined type.
