A movable lighting apparatus having multiple light sources comprising solid-state light units and arranged for the creation of sequences of simulated natural daylight in an indoor environment by controlling the mixing ratios and composition of light output of three types of spectral light, the three types of light comprising physiological light ranging from violet to blue, reading light ranging from green to red and mood light comprising amber colored light, whereby simultaneous emittance of mood light and physiological light is mutual excluded. The sequences are related to a natural daylight cycle of one or more geographical locations.
