Abstract

Artificial light at night (ALAN) adversely impacts nighttime scenery values. Current standards for LED lighting have led to brighter nighttime lighting, using color temperatures that are more harmful to human and ecological health, and which create an exponentially larger landscape impact than historical ALAN technologies. Less-harmful LED lighting and other existing technologies can be used to control artificial light at night, creating safe and pleasing perceptual nighttime experiences while minimizing ecological impacts. Minimizing the impact of artificial light at night requires understanding new lighting technologies, and management practices that extend beyond current lighting standards. This is crucial in order to sustain and protect the visual and cultural qualities of the landscape, and the ecological functions that we enjoy and depend upon. This paper will outline how the human body perceives and is affected by light, a key component to the success of implementing light pollution mitigation; discuss existing and evolving fixture programming technologies, and present challenges faced and lessons learned in implementing new lighting standards that support visual resource stewardship.
