Designed in 1956, the Model 566 embodies Gino Sarfatti’s reductive process, resulting in a balanced elemental form. The luminaire stands poised, with implied forward motion, lightening the contrasting body tube which holds the characteristic Cornalux bulb. The body tube is cleverly supported by a simple rubber ring that provides the perfect amount of friction for infinite adjustability. Punctuating the design, a familiar push-button on/off switch is incorporated in the base, providing a satisfying click.
