I downloaded an IES file from a leading lighting manufacturer and placed that file in the proper folder (location where the other IES files are). I go to the properties of the lighting fixture, and then edit the type parameter for the IES Data File name, I seem to be able to only type the name for that file. There seems to be absolutely no indication that the IES data file is associated with the lighting fixture. In that field for IES data name, I can type anything. Is there a way to be sure that the IES data file I downloaded is being applied to the fixture? Any help offered is appreciated.
