The challenge

In Japanese, sen means “line”. For Prolicht, it became the name of a lighting system that treats light as a continuous, spatial element that structures, connects and defines space. The system had to offer complete freedom to build, from straight lines to complex compositions flowing from wall to ceiling. At the same time, the design had to stay pure, and every module had to connect electrically quickly and reliably. Bringing those three together was above all a technical challenge.

Our solution

We reduced the system to its essence: a refined coupling system that brings the mechanical and electrical connection together and stays invisible within the line. Every element connects the same way, which allows a maximum of configurations, from a subtle, minimal line to an expressive spatial sculpture.

During Milan Design Week 2026, Prolicht featured its modular SEN lighting system in several key installations, as a precise tool to define spaces, guide sightlines and shape atmospheres.
