This session follows presentations and discussions from leading lighting practitioners and researchers. Our task in concluding the symposium is to work with the audience to make connections between the ideas presented. By highlighting the areas where we have good understanding of how lighting can influence behavior, we can clarify the ways in which designers can confidently use lighting to influence human behavior. By identifying areas where effects are uncertain, or many questions remain unanswered, we will develop questions that researchers need to address. Our aim is that everyone will depart the symposium with enthusiasm for the power of light and lighting to enhance our quality of life.
