One-third of outdoor lighting escapes unused into space, causing light pollution. Light pollution is a growing concern on many fronts: energy conservation, cost, safety, health, effects on wildlife, and our ability to view the stars. How we use illumination engineering to optimize where, when, and how light is used is of significant importance. We will discuss how NOAO's light pollution education kits are used to teach illumination engineering. In particular we will address topics associated with achieving sufficient ground coverage, color rendition, types of outdoor lighting, glare and sky glow, assessment of city lights, and task-oriented lighting.
