The Catellani & Smith Macchina della Luce mod. F is a pendant lamp, consisting of four vertically mounted diffusers. These diffusers have the shape of round discs, the top disc is the largest one with 120 cm diameter and the others are becoming smaller downwards. The other three discs have a diameter of 80 cm, 50 cm or 30 cm. The lower three discs are coated with a smooth foil, the top with flying foil. Therefore, and because the light source is located in the lower discs, the upper disc is illuminated. The discs are available in three different surfaces: copper, gold leaf or silver leaf. The metal rods on which the discs are fixed, have a total length of 145 cm and can be shortened if necessary. On request, the rods are also offered with a length of 300 cm. The rods in the silver leaf variant are nickel-plated, for the other two versions they are made of brass. The pendant lamp is on site dimmable. The included LED boards have a total power of 9 x 6 watts.
