Luminator floor lamp, 1994 (1955) Achille and Pier Giacomo Castiglioni Steel, 51 1/4 x 6 x 6" Manufactured by Gilardi & Barzaghi, Artform, and Flos Lent by Flos   As simple as a child's drawing, Luminator's main body is a tube just wide enough to accommodate the bulb socket. It rests on a tripod made of three sticks that can be easily stored and carried. The electric wire comes out from the bottom like a tail. This kind of indirect photographer's lighting was first suggested for domestic use by Pietro Chiesa with his Luminator (1933); in tribute, the Castiglionis also used that name.
