LDT file
The LDT photometric file format contains angular intensities, power consumption, physical dimensions, CRI, and color temperature. The angular intensities are stored in candela per kilolumen. The LDT format is mostly used in Europe.
TM33-18 file
The TM33-18 file is an extensive XML format which can contain all the data from IES and LDT files and much more.
