How this lamp was created, by Isao Hosoe

In 1967, when I arrived in Milan, I started working as a designer, even if I was an engineer, at the studio Ponti, Fornaroli, Rosselli.

I was discovering the world of industrial design with an unusual approach, reaching the concepts following my interests. At this moment my attention was concentrate on the possibility to use existing industrial components to create new objects.


In a store near the Columns of Saint Lorenzo, in Milan, I found a simple flexible tube that cost 20 lire per meter, so with a total expense of 1000 lire (half Euro), you could buy 50 meters of wrinkled electrical tube.

With this “precious” material I went to Valenti, the company that I was suppose to collaborate with.

I spent, together with the workers, the whole afternoon in the workshop of the company, cause I wanted to create a lamp from this tube.

We manage to find and assemble all the necessary pieces, except the base. It was a problem that we couldn’t resolve.

While we were talking, playing with this object, we understood. If we roll up the flexible tube, the lamp can support by itself, without any kind of base. In this way Hebi was born, and put in the production from 1970.


Produced by Valenti, Hebi had an immediate success, selling 5000 pieces in one month.

Hebi is a product that wasn’t designed, but had an immediate power of communication. It’s concept was the movement: the flexible tube folds, make soft curves and after a sensual dance finish illuminating with a small spherical diffuser.

The key point of the Hebi project is the “lack”, that here has a positive meaning. The lack of the base has simplified the project and has introduced you the creative component, that is a patrimony for everyone, everyone that interacts with this object.
