Inspired by the golden ratio and the Fibonacci spiral—geometries found in countless growth processes throughout nature—the work transforms the space into a sensory experience. Here, light is perceived as a presence that structures the environment, even as its source remains hidden.
The installation is brought to life through suspended threads that trace the curve of a spiral in mid-air. This subtle gesture creates an almost imperceptible choreography, connecting mathematical rigor with a poetic dimension. As the viewer’s gaze moves forward, an aluminum-paneled backdrop dissolves the boundaries of the room, multiplying reflections and projecting the installation into a visual infinity where form and light appear endless.
Arkoslight’s luminaires, featuring “The Invisible Black“ technology, integrate seamlessly into the space by disappearing from view, allowing light to emerge silently and precisely. The result is a soft illumination that accompanies the visitor’s journey, inviting them to pause, observe, and inhabit light as a material substance.
A dialogue between nature and technology
The project arises from a reflection on the existence of an origin or source that is not always visible, both in nature and technology. In the natural world, this order manifests through patterns like the golden ratio—a system of harmonic growth repeated in everything from galaxies to seashells.
Following this analogy, L35 Architects conceived a sculptural spiral piece that materializes this universal proportion. In it, the light is clearly perceived, but its source remains concealed, reinforcing the parallel between natural processes and “The Invisible Black” technology. The installation thus proposes a space where reason and emotion coexist in balance, inviting the visitor to do more than just understand it rationally: to feel it.
The creative process
To develop the project, Arkoslight and L35 Architects organized an internal, anonymous competition across three of the firm’s offices (Madrid, Barcelona, and Paris). “Spiral” emerged as the winner, proposed by Estefanía Davel, a senior architect from the Madrid team. The idea won unanimous approval from a jury composed of members from both firms.
The presentation of the space served as an opportunity to celebrate the collaboration between the architectural studio and the brand, highlighting the vital role of the architect in the conception of lighting.
