What is a .ULD file?
The .ULD file extension stands for Unified Luminaire Data File. This type of file is specifically used by a program called DIALux, which is a tool designed for professionals to plan and design lighting for various spaces, both indoors and outdoors. The .ULD file contains important information about different lighting fixtures, which includes descriptions of the fixtures, pictures of them, how much light they emit (luminous flux), how much power they consume, and even a 3D model that allows users to see how the fixture looks from different angles. However, it's important to note that users cannot create these .ULD files themselves; they can only use them for viewing purposes within the DIALux software.
DIALux is a popular and free software that is widely used for creating lighting designs for a variety of places like homes, office buildings, neighborhoods, sports facilities, and commercial areas. It helps in planning how to light up a space effectively, considering different elements of the room or area being designed.
To open a .ULD file, you would need to use DIALux or DIALux Evo, which is an advanced version of the software offering more features. These programs allow you to import the .ULD file and view all the detailed information about the lighting fixtures contained in it, helping you make informed decisions about lighting design.
It's worth mentioning that .ULD files are similar to other file types used by DIALux, such as .LDT, .ELD, and .IES files. These files also contain data about lighting fixtures but may include different types of information or be formatted differently.
