A disc with slightly rounded surfaces and edges, enclose two luminous devices designed to make the most of the emission of 96 LEDs directed downwards and 128 LEDs directed upwards. The intensity of the light can be adjusted independently, both upwards and downwards. Special raster optics avoid dazzle and decorate the horizontal surfaces of the disc with a pattern of concentric squares, and engravings in concentric circles contribute to heat dissipation. The very simple shape suggests and allows a complete range of applications (floor, table, suspension, and wall lamps) making it suitable to the most various contexts.
