Height-adjustable Costanza designer floor lamp with touch dimmer With its simplicity and elegance, the Costanza floor lamp has been a favourite among purists for several decades. in 1986, designer Paolo Rizzatto developed the luminaire series, which has been a Luceplan classic ever since. Costanza consists of a delicate aluminium frame that is height-adjustable (120-160 cm) thanks to its telescopic arm. The classically conical polycarbonate lampshade is screen-printed. A small rod protrudes from the lower end of the lampshade, which is used for switching on and off as well as for dimming (in four stages).
