7.4.2.16.2 Type values
| Type | 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
