In rooms and cabinets, MASTER long fixtures have been installed. Square MASTER panels have been fitted along the corridors, and in the loft areas converted into office space. When LED lighting is closely matched to natural light, it guarantees comfortable working conditions in rooms with irregular heights. MASTER panels have also been used in rooms in the basement of the library intended for working in, including in the archives. The narrow corridors and confined spaces have benefitted from MATIS LED fittings.
