CELUNA, our archetype, focuses on the unique aesthetics of Betonlicht. Suitable for both indoor and outdoor use, CELUNA has a luminous flux of up to 4000 lumens, which makes it ideal for extra-high indoor spaces in homes, commercial buildings or schools. CELUNA has a purist design that makes the concrete glow, and the light becomes one with its source.
Good to know
  • Betonlicht is seamlessly cast into the concrete ceiling.
  • CELUNA complements Betonlicht, providing a timeless lighting solution for exclusive architectural projects.
  • Working in harmony, the two components deliver uniformly distributed, dimmable light with an infinitely adjustable beam angle.
