Square LED wall light Basic made of aluminium The Basic wall light produced by German manufacturer GROSSMANN has a simple square shape throughout - from the flat frame made of roughly brushed aluminium to the matt acrylic diffuser and its shiny frame. The light, the intensity of which can be controlled via an external phase dimmer, is emitted in all directions and provides uniform ambient lighting. Thanks to the very good colour rendering, the objects in the room are presented realistically.
