The availability of reliable and accurate photometric data of the light sources is a fundamental requirement for any lighting designer for the plan of a good lighting system.


Our main partner for lights Cortem Group commits its lighting fixtures to specialized laboratories for the analysis of the lighting characteristics. On this page you can download, even in a single zip archive, .LDT and .IES lighting data files for the design and simulation of lighting levels in 2D and 3D, rendering and ray tracing. You can download the ZIP archives under “Other” on this web page.

More information about the lighting world and the correct interpretation of the characteristics of the lighting fixtures are available in the guide – Basic of ligtning engineering. You will find the document under “Other” on this webpage.
