Specifying an IES File for a Light Source
An IES file is a text file that describes the intensity of a light source at points on a spherical grid. It provides
more photorealistic lighting effects in rendered images than other types of light distribution. See
Photometrics
and IES Files
on page 1102.
Specifying an IES file for a light source is a 2-step process. First, in the light source definition, you must
specify Photometric Web for its light distribution. (To perform this step, you edit the lighting fixture family.)
Second, you must specify the particular IES file to use. (You can perform this step when editing the lighting
fixture family, or when modifying type parameters for particular lighting fixture in a project.)
To specify an IES file for a light source
1
Obtain the desired IES file.
You can obtain an IES file directly from the manufacturer, or use an IES file provided by Revit
Architecture. The Revit IES files reside in the following location, by default:
C:\Program Files\<product name and version>\Data\Electrical Components\IES
