Costanza designer wall light with cable and plug In 1986, designer Paolo Rizzatto created a light with a particularly timeless design. Costanza is an example of a design that is able to defy all trends and is consistently very popular. The frame of the wall light is made of aluminium and is complemented by a lampshade made of polycarbonate. In principle, a classic light like this has been designed without any distracting details - with one exception: the rod at the bottom of the lampshade is a practical and stylish reinterpretation of an on/off switch.
