Excessive and unrestricted light from bollards, columns, and post tops can negatively impact people, animals, and the environment. However, fixtures that are designed to Dark Sky specifications can dramatically reduce the amount of sky glow and light pollution while saving energy and mitigating impact on the environment. This learning unit will explore the concept of Dark Sky and how architects can specify luminaires to help reduce light pollution and encourage a healthier and more responsible approach to lighting.
