Sustainable lighting

Sustainable lighting is lighting designed with energy efficient light sources. "There are simple design strategies and some materials that can facilitate the energy saving advantages of natural light. Light colored interiors and open floor plans are good choices. This approach also augments artificial light efficiency. Energy efficient lighting is not simply finding the most light for the least wattage or the longest lasting light bulb. Proper sizing of the light to the needs of the location and the tasks that will be performed, called task lighting, is an energy saving strategy."

"The most sustainable source of lighting is daylight, other forms are solar lamps harvesting daylight and lighting controlled by occupation sensors. Furthermore technologies such as light-emitting diodes can be used to drastically reduce the energy requirement for energy. Part L of the UK lighting regulations contains criteria that effects efficient lighting design.
