The A330S is the more prominent design of A330. Created for The Savoy Restaurant in Helsinki, it bears the signature Alvar Aalto's streamline design ethics. It was also a part of the Finnish Pavilion of the Paris World Expo in 1937, the year it was created. The body lines flow starting with a small cylindrical section which transforms into a filleted dome. The small dome part diverges to form the more massive dome structure. The A330S comes in two major options - Golden Bell Savoy, a polished brass structure and Golden Bell. The Golden Bell design has various combinations of brass with polish and clear lacquer, chromed steel, steel with black lacquer, and steel with white lacquer. The body is a single piece hand-spun brass or steel structure.
The light fixture plug ends to a 2.5-metre long plastic cable which comes in two colours - black or white. The fixture calls for a 220-240V 50Hz power supply and can accept a maximum power of 40-watt. An E27 bulb is suitable for use with compatible energy classes of A++, A+, A, B, C, D, and E. The A330S comes with an appliance class II certificate and IP20 protection as safety assurance.
