Arkoslight introduces “Spiral” at its corporate headquarters, a temporary installation by the leading architectural firm L35 Architects. Drawing on the golden ratio and the Fibonacci spiral—geometries that recur in countless natural growth processes—the installation turns the space into a sensory experience. Light becomes a presence that gives structure to its surroundings while its source remains concealed.

Suspended threads bring the installation to life, tracing a spiral through the air. This delicate gesture unfolds as an almost imperceptible choreography, linking mathematical rigor with poetic expression. As the viewer’s gaze travels deeper into the space, an aluminum-paneled backdrop blurs the room’s boundaries, multiplying reflections and extending the installation into a visual infinity where form and light seem to continue without end.

Featuring “The Invisible Black” technology, Arkoslight’s luminaires blend seamlessly into the space, receding from view as light emerges with quiet precision. Soft illumination follows visitors through the installation, inviting them to pause, observe, and inhabit light as a material in its own right.

A Dialogue Between Nature and Technology

The project explores the idea of an origin or source that remains unseen, in both nature and technology. In the natural world, this underlying order emerges through patterns such as the golden ratio—a system of harmonious growth that recurs in everything from galaxies to seashells.

Building on this analogy, L35 Architects designed a sculptural spiral that gives physical form to this universal proportion. Light is clearly perceptible, yet its source stays hidden, drawing a parallel between natural processes and “The Invisible Black” technology. The installation creates a space where reason and emotion find balance, inviting visitors to move beyond intellectual understanding and experience it through feeling.

The Creative Process

Arkoslight and L35 Architects launched an anonymous internal competition across the architecture firm’s Madrid, Barcelona, and Paris offices to develop the project. The winning proposal, “Spiral,” was conceived by Estefanía Davel, a senior architect on the Madrid team, and unanimously selected by a jury with representatives from both firms.

The unveiling offered an occasion to celebrate the collaboration between the studio and the brand, underscoring the architect’s essential role in shaping lighting concepts.
