The lighting largely determines the spatial effect and can adapt to the use of an interior space. A variation of activities or a change under which these activities must take place often requires different functional lighting, architectural lighting and/or mood lighting. Changes in the light level and colour can also contribute to the synchronisation of our biological clock with the daylight cycle. That is why a lighting installation must immediately consider a light scenario that enables us to perform our visual tasks optimally and that contributes to our sense of safety, comfort, wellbeing and health.
