Can lighting controls add to light quality?
Yes, controls can definitely offer a lot in this area. Firstly they work psychologically, because they provide user control of aspects of the work environment, which most people enjoy. Controls can also offer versatility, by adjusting light levels for different types of people and work – for example older people tend to want more light. For advanced applications dynamic lighting, where the colour and intensity of light is varied throughout the day to mimic daylight, relies on sophisticated control to be effective. The idea behind dynamic lighting is that it can be valuable, particularly in the northern hemisphere winter, in reinforcing the human circadian day/night cycle that helps with health and well-being.
