The Castiglioni brothers often created designs that challenged our perspective, and the Taccia, which gives the illusion of an upside-down hanging lamp, is an inspired example of that. This new, smaller version is approximately half the size of the original design created in 1962. It has a painted aluminum reflector that is gloss white on the inside and matte white on the outside. The diffuser is transparent blown glass and can change direction. The body is available in matte black or naturally anodized extruded aluminum. The base is nickel-plated ABS and polycarbonate. 10-100% dimmer switch on cord. The plug-in power supply includes interchangeable plugs.

Achille Castiglioni said of Taccia in a 1970 interview: "We consider it the Mercedes of lamps, a symbol of success: perhaps because it looks like the shaft of a classical column. We certainly weren't thinking of prestige when we designed it. We just wanted a surface that would stay cool." Taccia was devised in 1958, designed and prototyped in 1959 and, after several years of study of the prototype by Flos to devise a mass production scheme, produced in 1962.
