Variation of light intensity and colour temperature throughout the day

Through research, we know that light affects us not only visually, but also biologically and emotionally. Light is important for our health and well-being, and it affects our level of alertness. It can also adapt and stimulate our biological clock as well as our psychological state.

Variations over time in lighting conditions, in terms of intensity, illumination levels, distribution, ambient lighting and colour temperature, can stimulate people’s alertness and well-being in a positive way. The recommended levels of these variations are being evaluated.
