.ULD File

File extension uld is mainly used for a special Unified luminaire data format used by DIALux 2 or higher.

Only the Project partners of DIALux are able (and allowed) to create this format. It includes all the information about the fixture (light distribution, possible equipment, fotos, text, 3D geometry,...).

Files with uld suffix can be mostly found as special light data files saved in Unified luminaire data format.

How to open:

Use DIALux to open and load up .uld files.

How to convert:

It is unlikely that this type of .uld files can be converted to anything else.
