IES Meeting Topic:

The International Dark-Sky Association (IDA)/Illuminating Engineering Society (IES) Model Lighting Ordinance (MLO) is an outdoor lighting ordinance template designed to help municipalities develop outdoor lighting ordinances that reduce glare, light trespass, and skyglow. This presentation will give an overview of the MLO with examples on how to apply it. Also, an overview of TM-15-11 Outdoor Luminaire Classification System commonly known as the BUG rating, will be presented since it is part of the MLO criteria.

The MLO was developed jointly by the IDA and IES. The IDA/IES partnership encourages broad adoption of comprehensive outdoor lighting ordinances.

Learning Objectives:

  1.        Understand the MLO purpose and impact
  2.        Learn how to apply the MLO prescriptive method
  3.        Experience the MLO performance method
