Soli is an outdoor lamp powered entirely by the vitality of the soil beneath it. It transforms the hidden life in the ground into a gentle glow, a quiet thank you from the earth.

At its core is a microbial fuel cell that generates electricity from the natural activity of microbes in the soil. As they break down organic matter, they release electrons that create a small but steady current. The healthier and more active the soil, the brighter Soli shines.

Designed as a symbol of reciprocity, Soli invites us to see the ground not just as something we use, but as something alive, responsive, and worth caring for. It becomes a bridge between the visible and the unseen, an object that makes the wellbeing of the earth both tangible and beautiful.
