A 300-watt car headlamp was the inspiration behind the Toio floor lamp designed by Achille Castiglioni and Pier Giacomo Castiglioni.
The Toio was part of the brothers’ ready-made objects series, and included the use of parts of a fishing pole in addition to the headlamp imported from the USA.
Placed along the floor lamp's nickel-plated brass hexagonal stem are fishing rod rings used to guide the electrical cord from bulb to transformer. This transformer acts as ballast by being located at the base of the height-adjustable stem.
A cleat on the base is provided to keep the cord neatly coiled when the lamp is adjusted to a lower height. Considered a design classic, the Toio floor lamp is part of the permanent collection at MoMA in New York City.
