.DLC File Extension
What is a DLC file?
File created by DIALux, a professional application that enables you to model and plan lighting for indoor and outdoor area; contains information about light scenes and control groups used by the DIALux program to control the dimming and color value of light fixtures; exported in order to be read by a Digital Addressable Lighting Interface (DALI) system and program the settings for a light system.
To create the DLC file, select File → Export → Save DIALux light scene file..., choose the save location, name the file, and click Save.
NOTE: There currently are no DALI systems that use the DLC file.
