Square LED wall lamp Basic made of aluminium in black The German manufacturer GROSSMANN has designed its Basic LED wall lamp in a square shape. This motif is taken up by the black, roughly brushed aluminium frame as well as the square diffuser made of matt acrylic plastic and its shiny frame. The light output of Basic can be controlled with external phase dimmers. This creates a needs-based basic lighting on all sides, which also allows the other furnishings in the room to appear in their natural colours thanks to the high-quality LEDs.
