This article describes what an IES file is, how to open it online or on your computer, and how to convert it to another format so that it is compatible with other programs.

A file with the IES file extension is an IES Photometric File, which stands for Illuminating Engineering Society. It is a plain text file that contains data about light for architectural programs that can simulate light.

Lighting manufacturers can publish files in this format to describe how different structures are affected by their product. The program that uses the file can interpret it to understand how to display the correct lighting patterns on things like roads and buildings.

There are several compatible programs: Photometrics Pros, Photometric Toolbox, Autodesk's Architecture and Revit software, RenderZone, the visual lighting software, and Photopia.
