List of values

Detailed values

lamp_type=* is used describe the highway=street_lamp illumination source.

Key	Value	Element	Comment	Rendering	Photo
lamp_type	gaslight		The light source uses gas.
lamp_type	fluorescent		The light source uses a fluorescent lamp.
lamp_type	halogen		The light source uses a halogen lamp.
lamp_type	incandescent		The light source uses a traditional incandescent lamp.
lamp_type	led		The light source uses light-emitting diodes.
lamp_type	metal-halide		The light source uses a metal-halide lamp.
lamp_type	mercury		The light source uses a mercury-vapor lamp.
lamp_type	low_pressure_sodium		The light source uses a low-pressure sodium lamp.
lamp_type	high_pressure_sodium		The light source uses a high-pressure sodium lamp.

Generic values

The following values are acceptable, but they are very generic since there are many distinct variations, such as low pressure sodium (SOX) lamps, high pressure sodium (SON) lamps, and LED lamps. They should be replaced when the type of lamp is known.

Key	Value	Element	Comment	Rendering	Photo
lamp_type	electric		The light source uses an electric lamp of an unknown type. Please use one of more specific values above.
lamp_type	floodlight		The light source is a floodlight of an unknown type. Consider using actual lamp_type=* (e.g. lamp_type=halogen), and adding light_source=floodlight instead.
lamp_type	sodium		The light source uses a sodium lamp of an unknown pressure level. It is preferred to use low_pressure_sodium or high_pressure_sodium if it is known.
lamp_type	solar_lamp		The light source is powered by a solar panel. lamp_type=solar_lamp is a generic value, because solar-powered street lights may not always use LEDs. Consider using actual lamp_type=* (e.g. lamp_type=led), and (if needed) adding electricity=solar to indicate source of electricity instead.

Future

A proposal exists to replace this key with light:method=* or light_source=*, as part of a review how editors tag lighting in a broader context. For more information, see this proposal for light_source=*.
