Successful design with dimmer and telescopic technology - Costanza table lamp The successful Costanza light design has been around since 1986. The Italian designer and co-founder of the Luceplan light company, Paolo Rizzatto, created a true icon and a real classic among lights with this timeless design. The Costanza family of lights is characterised by the conically shaped lampshade, which is made of high-quality polyurethane and fixed in place with press studs on the side. It is easy to replace and allows light to be emitted upwards and downwards. The brass-coloured frame of the Costanza is also adjustable in height from 76 to 110 cm and has a small rod at the top that can be used to switch the table lamp on and off and make it dimmable. The dimmable function has four levels and only requires a brief touch of the rod to start the process.
