The International Dark-Sky Association (IDA) and the Illuminating Engineering Society of North America (IESNA) Joint Task Force is developing a Model Lighting Ordinance (MLO) to address the need for strong, consistent outdoor lighting regulation.  

The MLO will soon be available for public review and comment.  The current draft is considered to be approximately 90% complete, and will include an accompanying "Design/User's Guide". Check back to this page for updates on the next public review.
