What Is an IES File? An IES file, or Illuminating Engineering Society file, contains photometric data on light for programs to simulate lighting. These plain text files follow the format of the Illuminating Engineering Society (IES).
An IES file has measurements of light and quantities. Building designers and engineers use them to simulate lighting when designing structures like buildings and roads.
One can open IES files in viewers and convert them to other formats. IES-compatible programs include 3D graphic programs. All devices can transfer IES files. However, not all systems open them properly.
Only the latest software versions support the current IES format. One should also scan IES files for viruses using antivirus software.
IES files contain photometric data on light measurements and quantities in the format of the Illumination Engineering Society of North America (IESNA). Programs like 3D Studio Max import this data. The IES format can likely be exported to other photometry file types.
IES files allow simulating lighting systems before implementation and studying lighting design. Manufacturers often publish them. Software supporting IES files includes architectural and 3D graphic programs.
