how do create a RGBW ies file?

How do we make RGBW IES files like "DIALUX finder"?

Our IES only has one lamp in the IES file, and it is non-color.

Hi Huang!

To create RGBW luminaires, DIALux requires some spectrum information. Those are not part of IES or LDT files. As a result, it is not possible to create such luminaires in these formats.

ULD or GLDF files support this feature, but it is restricted to DIALux member only.
