Flos Arco Floor Lamp with marble base

Flos Arco is the legendary floor lamp designed in 1962 by Achille and Pier Giacomo Castiglioni: a timeless icon of Italian design, among the most imitated and admired in the history of lighting. Its structure combines a white Carrara marble base — acting as a counterweight — with a long arching arm in aluminium that elegantly extends towards the centre of the room, bringing direct light from above without any work on the ceiling. The hole crafted into the centre of gravity of the base is a stroke of design genius: it allows the lamp to be moved simply with the help of a broom handle.

An icon for every space

Arco was created to answer a concrete need: achieving the light effect of a pendant lamp without drilling into the ceiling, making it ideal both for the living room — where it illuminates dining tables or creates striking reading corners next to the sofa — and for showrooms and high-profile contract environments.

A revolutionary design intuition

The Arco project was born from a question as simple as it was brilliant, posed by the Castiglioni brothers: how do you bring light directly onto the dining table without intervening on the ceiling with wiring or drilling? The answer was an arching arm capable of "suspending" light from a floor-standing point far from where the light needed to fall. This seemingly simple solution required sophisticated structural calculations to achieve the perfect balance between the weight of the marble base and the cantilever of the aluminium arm, a balance that still makes Arco a case study in design schools around the world today.

Technical specifications

The structure reaches a total height of 2,400 mm, with an arm length between 2,140 and 2,240 mm and a base measuring 235 x 550 mm. The E26-E27 lampholder is compatible with voltages from 100-240 V (EU, USA, UK, AUS, JAP) and the 2,700 mm power cable ensures great flexibility in positioning. The lamp features an ON/OFF switch and provides direct light emission; the bulb is not included.

Why choose the original Flos

Arco is among the most reproduced design pieces in the world, but only the original Flos guarantees the materials, craftsmanship and proportions designed by the Castiglioni brothers. Choosing the original means relying on certified build quality, selected Carrara marble and aluminium engineering that ensures correct weight distribution and structural safety over time — a value that imitations simply cannot replicate.

A timeless classic

More than sixty years after its debut, Arco remains an absolute reference point in Italian design, held in the permanent collections of the world's most important museums.

Frequently asked questions about Flos Arco
