The Teorema, designed by Ferruccio Laviani in 2005, is a sculptural floor lamp in chrome-plated metal, with white or colored elements that protrude from a central structure. A polycarbonate screen contains the luminous core, and varying perforated patterns on the shade give the light a textured effect. Teorema is equipped with a double on-off switch for simultaneous or independent use. please note that this lamp requires two different bulbs.
