Questions and answers

  • What is the file format .LDT and what does it typically represent?

    The .LDT file format stands for "Laser Data Transfer" and is commonly used in the lighting industry. It is a standardized file format developed by the International Commission on Illumination (CIE) for transferring photometric data of luminaires.

    Typically, .LDT files represent the photometric data of a specific lighting fixture, providing information about its light distribution, intensity, and other characteristics. These files contain detailed measurements and calculations that allow lighting professionals to accurately analyze and simulate the performance of luminaires in various lighting design software applications.

  • How can I open a .LDT file and what software or tools are required for it?

    To open a .LDT file, you will need software or tools that are specifically designed for handling this file format. .LDT files are typically used in the lighting industry and contain data related to luminaire photometry, such as light intensity, distribution, and color.

    Here are a few software options that can open .LDT files:

    1. Dialux: Dialux is a popular lighting design software that supports .LDT files. It allows you to import .LDT files and use them for designing and analyzing lighting systems.
