The Global Lighting Data Format (GLDF) is a modern, open standard for exchanging lighting product data. It combines 3D geometry, photometric data, electrical specifications, and product metadata in a single container file.
GLDF is developed by DIAL and RELUX and supported by major lighting manufacturers worldwide. It enables architects, lighting designers, and engineers to work with accurate product data in their design software.
