Bulbo57 by A. and P.G. Castiglioni

Bulbo was designed for an installation at the XI Triennale in Milan in 1957. A large industrial bulb deprived of its screw cap and with a shortened neck to take the shape of a bubble, with a filament inside as the distinguishing feature. The 2019 edition by Flos reproduces the classic filament in tungsten with an LED source, preserving the same color and intensity of the light as in the original
