  Abstract The subject of limiting outdoor lighting seems straightforward- it saves electricity and reduces glare, but society has a predilection for activity at night that requires more than natural light. This extends beyond urban areas. “Cottage country” is well lit along the shoreline, and even campgrounds filled with amateur astronomers have lots of unshielded lights. Although these tend to be red, they still undermine our night vision (Dick, 2016) and change the nocturnal ambience. The main problem of whether outdoor lighting is good or bad depends on who is judge. Is there a less equivocal way to assess or define acceptable outdoor lighting, especially in rural areas? Must rural lighting follow “Best Practices” for cities? This is the first in a series of papers that will discuss the science behind the ecological impacts of artificial (anthropogenic) light at night. It will propose rational solutions to reduce these impacts and will define the characteristics of artificial light that minimize these disruptions that we call lighting with “low-ecological impact.” Although taking an ecological approach to outdoor lighting is unusual, we have observed that if the nocturnal environment is preserved for wildlife, it is usually sufficient for astronomy. Although it is understood that observatories may require a curfew during the three weeks centred on the new Moon. This first paper will set the stage for this somewhat unorthodox exploration into light.
