This guide is based on chapter 1 of the forthcoming updated edition of the SLL Code for Lighting and has been produced as a free stand-alone document to act as an introduction to light and lighting for all those with an interest in the subject. It starts by looking at the issues that affect the quality of lighting and task performance before going on to look at how light affects behaviour, safety and perception of objects and space. The final sections look at lighting and health, and cost and pollution issues.
