The Hera Sky Window - brings light into the darkness - everywhere (EN) 

The Hera Sky Window is a bright and powerful LED panel with the look of a typical roof window. Due to the extremely flat design, daylight effects can even be achieved in rooms where it would not be possible on site: e.g. as a ceiling window in basement rooms, as a skylight in shopping malls or simply as an additional window in interior windowless rooms and corridors. The daylight ambience (HCL) of the Sky Window is created by the simulated illuminated sky and the solar radiation that can be switched on. The result is amazingly real daylight effects.
