A shallow aluminum dome, enameled with white heat-proof paint, is positioned on top of a deep bowl and becomes the reflecting screen of the table lamp. A bulb is hidden inside the metal base, which is corrugated to better disperse the bulb's heat. The bowl, which rests unattached on the base, moves to adjust the light's direction.

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.

Taccia features a metal base, aluminum reflector and transparent diffuser. The diffuser is now offered in two choices, hand-blown glass or methacrylate plastic. The base is available in your choice of 3 finishes with an LED light source.
