DIALux is used as a planning tool by over 680 000 lighting designers worldwide. With this free software you can design and visualize light professionally - single rooms, whole floors, buildings and outdoor scenes. DIALux constantly undergoes further development and meets the requirements of modern lighting design and lighting calculation.
ULD is the best data format for importing a luminaire into DIALux. Compared with conventional photometric formats such as IES or LDT, ULD files include many more features and much more product information so that data quality and calculation results can be substantially improved. Very complex luminaires can be shown, e.g. those consisting of several parts or light emissions.
As a premium partner of DIALux, we are now offering ULD files on the product pages of our website, allowing you to easily import each luminaire into DIALux with comprehensive information for your lighting calculations. Transferring the information into DIALux lighting design software can be done via drag & drop for immediate use.
Additionally, our products are also presented in LUMsearch, a luminaire search engine from DIALux where you can easily find the right luminaire and send the corresponding ULD file to DIALux.
If there is no ULD file available, you can still use our RELUX or LDT/IES files for your light calculation.
