support=*– Type of support/mount or positioning for the light source.light:method=*– Which light generation method/technology is used (values as forlamp_type=*, e.gelectric,led,fluorescent).light:colour=*– Colour of the emitted light, e.g.5000 K,white,orange,560 nm.light:lit=*– Time of day the light is turned on or method by which it is turned on (values as forlit=*, e.g.24/7,dusk-dawn,20:00-08:00,automatic).light:tilt=*– Angle of inclination of a directed light source. The range of this value is from-90(pointing downwards), through0(pointing horizontally), to90(pointing upwards).light:direction=*– In which (map) direction does a directed light source emit most of its light? Use an angle or a cardinal direction as a value (e.g.45,270,NE,W).light:shape=*– What kind of shape does the light source have? This determines the way the light is distributed. Typical values are:cylindrical– The light is emitted around a rotation axis.
directed– The light is emitted mostly in one direction.
spherical– The light is emitted in all directions.
light:count=*– How many light sources are there (on a lamp pole, for example)? The default value is 1.
