BIS is a lighting system made up of two light sources that, by means of a unidirectional mirror, can give off a soft glow or a strong burst of bright light, making it visible as an object and constituting a real spotlight. It has a compact section that makes it versatile since it is possible to house it inside plasterboard partitions or in masonry walls, but it is also possible to use it as a surface luminaire.
It can be used to bathe walls, ceilings and floors, to signpost passageways or to homogeneously illuminate large spaces, while achieving great effects not only in terms of lighting but also in terms of architecture thanks to its mirrored surface.
