The Model Lighting Ordinance (MLO), produced jointly by the Illuminating Engineering Society (IES) and the International Dark-Sky Association (IDA), provides a template for municipalities seeking to develop standards for responsible outdoor lighting. Specifically, the MLO addresses skyglow (light emitted up into the sky that obscures nighttime viewing of stars), light trespass (light emitted onto neighboring property), and glare (excessive brightness that impairs or disables vision).
