The Catellani & Smith Telchisugio is a wall lamp, consisting of a reflector disc hanging on the wall. This reflector lamp is illuminated by a diffuser on a flexible lamp arm. The flexible light arm allows the diffuser to be positioned variably above the disc, allowing the disc to be illuminated in different ways. The lamp arm has a diameter of 0.6 cm. The reflector disc is made of aluminum and has a diameter of 50 cm. Three surfaces are on offer for the reflector disc: covered with gold leaf, silver leaf and copper. For the copper and the gold variants, the remaining components of the wall lamp are made of brass, for the disc with silver leaf they are nickel-plated.
