bDescription/b The lamp with its large metal shade gives off a rich, uniform light, filtered by a white diffuser. In the Nova hanging lamp, with its distinctive mushroom-shaped metal shade, an attractive cylinder provides the counterweight for a traditional height-adjustable pulley system. Rationalist design provides intelligent technical solutions: the movement of the cylindrical counterweight is cushioned by a hidden spring which stops it striking the shade. The end of the pulley is hidden in the ceiling rosette. It uses fluorescent tube instead of incandescent bulbs. Because the fluorescent tubes do not heat up, the lamp can be raised and lowered without burning one's fingers. The metal shade is made using the lost wax technique, a process that dates back to the Middle Ages. Craftsmen shape metal sheets on lathes, using burins - a technique which requires considerable skill and precision. The inside of the metal shade is painted in a light mother-of-pearl tone to give the fluorescent lamps a warmer feel. A translucent screen beneath the bulbs is used to conceal the tubes and to shed the light more evenly. bMaterials Finishes/b Satin finished nickel lampshade (height adjustable lampshade due to a pulley system).
