Preben Dal (1929-1980) had a design studio in the 1960s and 1970s. He created the Symfoni lamp series in the 1960s. Symfoni lamps were produced by Hans Følsgaard Elektro. Symfoni lamps were available in different sizes (diameter from 20 to 68 cm) and different shapes, as pendant or wall lamps. White and dark grey-black painted metal diamonds assembled to an origami style lampshade. Out of production for many years. Lamp is in very good condition. No repairs, no damages, just light traces of use. Hard to find in this condition.
