Lang is the post top luminaire designed by Danish lighting design firm ÅF Lighting awarded with German Design Award 2019. It is a design tool that allows to play with light, the two independent light sources with their four different geometries, can generate a lumen output between 1,500 and 15,000, whilst the ‘blade’ can be customised to enhance the identity of a place.
Lang's two light sources not only minimise the shadow generated by the post top structure, but allow endless custom configurations. Lang is available in Basic, Ready or Pro version.
The ‘Basic’ version is equipped with only one source and can be adopted every time the area adjacent to the illuminated one has to remain dark or does not need lighting. Light distributions available are symmetric and asymmetric, types: II, III, IV, V; lumen output ranges from 2,500 to 7,500.
The ‘Ready’ version is equipped with two light sources and a shared driver. This version comes in five standard and most commonly used configurations. The four light distributions have been already combined together whilst ten different lumen outputs for each source can be selected and adopted; lumen output ranges from 5,000 to 15,000.
The ‘Pro’ version is fully customisable. The two sources could be completely different one from the other in terms of distribution, flux and intensity, allowing lighting professionals total freedom. The independence of the two light sources and drivers is the equivalent of having two luminaires mounted on the same post at same or at different heights. There are three different screen options to choose from: prismatic, transparent or opal-white (same glass choice for both sources). Lumen output ranges from 1,500 to 15,000.
