Borne out of a 1971 collaboration between Achille Castiglioni and Pio Manzù, the Parentesi Ceiling Light was named for the parenthesis symbol-a visual reference to the nickel-plated shaped tube that lives on a floor-to-ceiling steel cable. The steel cable can reach up to 157", and the tube allows the lamp head to move vertically along the cable to achieve a customized height.

Lamp bulb and dimmer are sold seperately.
