What is an IGF file?

IGF files mostly belong to DIALux evo. IGF files serve a specialized role in professional environments. They are used to store detailed test data for two main purposes:

Lighting Test Reports – These files are used by DIALux evo. They record measurement details and simulation parameters for photometric evaluations under the Photoluminescent Design & Analysis (PLDA) process. This information helps validate light distribution and intensity. For more guidance, visit the DIALux website.

HVAC Data Files – In some cases, IGF files log trend data for heating, ventilation, and air conditioning systems. This data may include sensor readings and performance logs, and is handled by software such as TrendXpert or TrendReader.

FilExt.com tip: These files are built in a custom format. They are not meant to be edited with simple text tools and must be opened with the authorized software.
