Costanza floor lamp: classic design with dimmer and telescopic technology As early as 1986, the designer Paolo Rizzatto developed the Costanza lamp series, which is characterised in particular by its timeless design and simplicity. The floor lamp of the series consists of a delicate yet stable frame made of aluminium, which is height-adjustable (120-160 cm) thanks to a telescopic device. On top sits a classically shaped lampshade made of polycarbonate with screen printing. At the bottom of the shade, a small rod sticks out, which is used for both switching on and off as well as for dimming (in four steps).
