INCONTROLUCE
For once, we switch off the light to illuminate, and switch it on to tell a story.

UMASI S
The magic of a lampshade. An invitation to rediscover, in light, a form of simplicity.
The light reveals itself without ever appearing directly.
It passes through three layers, transforming into a soft, enveloping material. Shadows dissolve and the space slows down. It is a quiet presence, capable of evoking a deep sense of familiarity. Switching it on is never an intrusive gesture, but a gentle breath that spreads through the room.
UMASI S is an essential suspension lamp that naturally adapts to domestic settings, creating intimate and measured atmospheres.

Available in two sizes. the roses available are in textured matt black or matt white painted steel. The lampshade is made of PETG, coated inside and out with paper, to ensure a soft and even light diffusion. The light source is an integrated LED module. The electric cable is in matt white or matt black, depending on the luminaire finish. A range of roses and power supplies are available. Floor version also available.
