IES/LDT Files
and 
Revit Family

IES and LDT files are photometric data files used in professional lighting design to describe how a luminaire distributes light in real space. They are essential for accurate lighting calculations, simulations, and compliance with lighting standards.

​Revit lighting families are digital BIM objects used in Autodesk Revit to represent lighting fixtures accurately within a building model. They combine geometry, technical data, and photometric performance into a single object that designers, engineers, and architects can coordinate across a project
