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. |
