IES file generator

Build an approximate photometric IES (IESNA LM-63) file for a luminaire: set the power, luminous flux and size, pick a light-distribution curve and the spot symmetry, preview it in a live 3D room and download the .ies file.

Important

This produces an approximate photometric file from a parametric model — useful for quick studies, mock-ups and testing. It is not a measured laboratory (goniophotometer) file and should not be used for certification or as a real product datasheet.
