FLOS was founded in 1962. The very same year it began producing a number of lamps that were to become classics in Italian industrial design. These first lamps were Arco, Relemme, Toio and Taccia — all designed by Achille and Piergiacomo Castiglioni.

From the very outset, its distinguishing feature has been the high quality approach to lamp design and production. Many of the numerous lamps designed for Flos, first by Achille and Piergiacomo, are undoubtedly some of the best-known and most successful products of industrial design. They have won awards and historical-critical accolades, and are included in all the most important collections and design museums around the world.
