IES is a standardized extension and format, which stands for Illuminating Engineering Society.

IES files are data files created to store measurements and amounts of light.

It is often used to simulate lighting systems in buildings before they are installed.

IES files, in general terms, are used to examine the illumination of the light source both indoors, as well as on roads and other places outdoors.
