CIELUMA is an integrated Architectural light system, in which technical light and acoustical requirements are optimally combined.

CIELUMA is a fabric & light module in which technical light innovations and the acoustical and photometric material properties contribute multiple benefits simultaneously. With its pure and even construction – without visible design features – the system is ideal as a lighting and acoustical element which gives the architect and lighting planner the freedom to make their own stylistic marks on the ceiling.


Light ceiling, light wall, stand alone or together.


Optimal lighting and acoustically effective materials make a measurable difference to personal comfort and well-being in spaces dominated by hard construction materials such as concrete, tile, glass, and metal. The positive effect on spatial acoustics through the application of two layers of SEFAR Architecture fabric is achieved because the double membrane acts like an air cushion, noticeably reducing direct reverberations, reflections and echoes. Benefits, which could otherwise only be achieved by the addition of echo-reducing structures.


Uncompromising. In every detail.
