Data that should be contained in a single line (according to the original IES file format spec) is spread over several lines, so it is necessary to read each angle and candela value one at a time instead of all in one line. I have also realized that some manufacturers (eg GE, Philips) create non-compliant IES files anyway.

Even a pdf of the file format specifications for IES LM-63-2002 is only available at a cost of US$20 (. Unfortunately IES (Illuminating Engineering Society) seems to be strongly focussed on profit.

I think they use the term 'open' to mean free, not open source. photometric data import and export in standard formats: CEN 13032, Cibse TM14, CIE 102, Eulumdat, IESNA 86-91-95-02, IES TM-33, UNI. That would be nice, but I couldn't find any reference to source code. Photoview is a powerful program for processing photometric and spectrum data of luminaires and light sources which includes the following functions: display and printout of graphs and charts. If this converter code is open source we could integrate it in the addon or Luxcore.
