Height-adjustable Costanza designer floor lamp with a classic look The Costanza floor lamp, which was designed by Paolo Rizzatto in 1986 and is still a popular luminaire model from Luceplan today, impresses with its simplicity and elegance. The frame is made of aluminium and is equipped with a telescopic device that allows the height to be adjusted from 120 to 160 cm. The lampshade, which is conically formed, is made of polycarbonate and has been screen-printed. Pressing the small rod protruding from the bottom of the lampshade switches the light on or off.
