The lighting for the stands at all of Osram’s trade fairs drew on the latest generation of halogen lamps available, that were carefully incorporated in the display system. "The stand was designed with gently flowing, almost mathematical aluminium structures glittering with bits of glass and decorated with a sky lit up by 60 small but brightly shining stars. The use of tiny 12V 100W halogen lamps, with no shields or lighting appliances, is the most distinctive feature of the entire lighting system and the optical position of the stand itself. Designed by the architects L. and P. Castiglioni, it was supposed to be a "light centre" focusing closely on the theme in question and fully visible from all sides, without any obstacles or useless structures to impede it (Notiziario Osram, 1-2, 1975)
