Supported by a round brass fitting on a marble base, this floor lamp is composed of a rotating brass stem that simply rests on a marble sphere used as a centre of gravity.

The counterweight mechanism is central to the ingenuity of this design. By balancing the adjustable arm through a simple mechanical principle, Sarfatti achieves effortless movement without compromising the lamp's slender silhouette.

Rather than concealing its engineering, he makes it an integral part of the design. Every component serves a purpose, and the relationship between balance, movement and light becomes the defining character of the lamp. This economy of means perfectly illustrates Sarfatti's approach to lighting: finding elegant solutions to practical problems through technical invention rather than unnecessary decoration.
