A linear lighting system simulates daylight during the different months of the year in a closed and windowless space. The system, connected to a satellite time clock, has four dimmable circuits, each one with different colour temperature lamps - warm, medium, cold and very cold - which vary in intensity according to differing times of the day, month and year. The light changes continually during day lit hours. This indirect light eliminates reflections in the numerous computers screens. To overcome maintenance problems, as scaffolding can not be erected, a complete hydraulic system allows each boom to be lowered from the ceiling to floor level.
