As the light bulb itself evolved a lot through years, light control systems are still switch\-based and require users to make most of the decisions about its behaviour. This paper presents an algorithm for emergent behaviour in a lighting system to achieve stable, user defined light level, while saving energy. The algorithm employs a parallel design and was tested using JCSP.
