Lighting control not only enables the lighting to be adjusted to suit the visual requirements but also allows it to shape and interpret the architecture. Light scenes are easily set up using the appropriate software and can be recalled via an interface. The inclusion of light colours and the time dimension opens up a room for scenographic lighting with dynamic effects. Lighting control systems with sensors or time programs also help adjust the power consumption in a room to its usage and thus optimise the economic efficiency of a lighting system.
