Height-adjustable Costanza pendant light from Luceplan The Costanza pendant light is one of the classics from the Italian lighting manufacturer. It was designed by Paolo Rizzatto back in 1986 and has been one of Luceplan's most popular products ever since. The lampshade of the pendant light has a classic shape and is made of polycarbonate with a screen-printed surface. The special feature of this model is its height adjustability. Thanks to a rise and fall mechanism with a stainless steel counterweight, the height of the light can be adjusted from 100 to 250 cm.
