What is a .LDT file?
An LDT file is a type of data file specifically used for storing information about light fixtures, also known as luminaires. This file format is used in conjunction with DIALux, which is a specialized software application designed for lighting professionals to plan and design lighting setups for various environments such as homes, offices, commercial areas, and outdoor spaces.
The content of an LDT file includes detailed specifications of a luminaire, such as the number of lamps it uses, the intensity of the light it emits, how the light is distributed, and the physical dimensions of the fixture. These details help in accurately simulating and planning lighting designs using the DIALux software.
To create or modify LDT files, you can use several programs: - **DIALux Evo and DIAL LDT Editor**: These are provided by DIAL, the company behind the Eulumdat format. DIALux Evo is used for comprehensive lighting planning, while LDT Editor is specifically for creating and editing LDT files. - **ReluxSuite and OxyTech LITESTAR 4D Open**: These are alternative professional lighting design software that can also handle LDT files. - **Meduza Photometric Toolset**: Another tool for working with photometric data, including LDT files. - **Eulumdat Tools ELUMDAT to IES Converter**: This is useful if you need to convert LDT files to the IES format, which is another common format used in lighting design.
For simpler tasks, such as viewing or making small changes to an LDT file, you can use basic text editors like Microsoft Notepad or Apple TextEdit, which are included with their respective operating systems. Although GitHub Atom, a popular text editor, was mentioned, it has been discontinued.
In summary, LDT files are crucial for professionals in the lighting industry, allowing them to manage and apply precise lighting specifications within design projects using various software tools tailored for this purpose.
