These formats combine different requirements. Modern data formats that are used in CAD and lighting design programs include ULD (DIALux) ROLF (RELUX), RFA (Revit) or even IFC (OPEN BIM). This format cannot be used for light planning. This is designed for data exchange between the manufacturer and retailer, and compiles product descriptions. These formats contain very little further information that would be required for a complete BIM-process, including system design, commercial processing or facility management.įor information required by retailers, for example, there is the ETIM format which is common in Germany and also used in other countries. Measured properties are presented and can be interpreted using formulas and standardised application rules. These formats document physical properties of lights and lamps. Standard photometry formats such as Eulumdat, LM63, TM-14 or UNI 11733-2019 are available for creating technical data sheets or calculating a lighting system. Various descriptions for lights are currently available for different purposes.
Manufacturers are incentivised to maintain the information and keep it up to date as they no longer need to create new formats for many different purposes.Ĭurrent status of electronic lighting documentation

Software manufacturers can find great information for their (design) programs. The information is always identical, ruling out differences between different file versions. The file can be used by all programs and applications. Planners can find all information on a product in the GLDF. All processes operated by manufacturer data can access the information from the GLDF. The Global Lighting Data Format (GLDF) provides the following advantages for everyone involved: Manufacturers only need to maintain and offer a single format. This data must include all information required for the respective purpose. Software manufacturers require comprehensive and the most up to date product information. Planners and designers use several different programs for different purposes and expect product data to be available, and of course uniform, across all applications. Until now, manufacturers have had to deal with the fact that users require internal product information in different formats and for different purposes.
