St. Martin's Church in Kassel is the seat of the Bishop of Kurhessen-Waldeck. The church is frequently used for events and thus requires highly flexible options for lighting the interior of the church. At the same time, the simple lighting from the 1950s, which had come to be well loved, was to be retained at the congregation's request.
The solution combined the old glass pendant luminaires with new, freely adjustable LED spotlights on the cross vaults to illuminate the stage and alter room, the organ and special works of art.
