DALI systems enable personal dimming control for occupants. Why should occupants be given personal control?
Studies indicate that office workers have a wide range of light level preferences, and feel they would be more satisfied if they had control over their lighting. However, lighting systems are typically designed as fixed-output systems, a one-size-fits-all approach. Personal dimming control allows occupants to choose their own light levels. One office lighting field study, conducted by the Light Right Consortium, revealed that office workers were more satisfied, vigilant and motivated with an indirect lighting/wall washing scheme with personal dimming control than with standard parabolic fixtures.
