Arco lamp: real Flos or replica? The 10-second base test

The world's most copied arched floor lamp. Carrara marble, steel, the hole in the base: the differences that matter, what a vintage one is worth, and what a €200 replica hides.

“arco flos imitazione”, “lampada ad arco replica”: it is one of the most searched-for lights in dupe form, above all in Italy. The Arco — the steel arc that lights a table with no ceiling fitting — exists as a genuine Flos and in a thousand copies. Here is how to tell them apart.

The original

Designed in 1962 by Achille and Pier Giacomo Castiglioni for Flos: a Carrara marble base, a telescopic brushed steel rod, an adjustable reflector. A feat — casting light 2 metres from its base.

Spotting a real one

The marble

A solid block of Carrara, heavy, with a through-hole (to slide in a broom handle and carry it between two people) — an original detail. Copies use a reconstituted marble, lighter, sometimes with no hole.

The steel and the logo

Quality brushed steel rod, a clean join, the Flos marking. Replicas use a thinner, shiny chrome that scratches easily.

Vintage versus new

A documented vintage Arco (1960s–70s) is often worth more than a new one. Check the condition of the marble and the steel, and the provenance.
