AbstractFor solid-state lighting to make a major dent in the lighting energy budget will require light sources and luminaires that are more efficacious than the existing technology, and a reason for building owners and tenants to change to an initially expensive, new and unfamiliar technology. New luminaire designs and operation modes using the unique characteristics of SSL will aid this transition. The ability to individually tune the light source colour is one such characteristic. Building on prior research concerning the benefits of individual control over illuminance, this experiment tests the effects of tunable light source colour and initial LED spectrum on office workers? cognitive performance, mood, and satisfaction over the working day.
