After starting the GDTF initiative in 2018 as a member of the GDTF group, we have been focusing on providing specification and tools for convenient creation of the General Device Type Format files. You can read more about this innovative format in our

To help to understand the benefit to the user workflow and cooperation, see for example 

 with Veith Schmidt, where he talks about how teams can use this unifying format to work together without having to duplicate their work and effort.

We have been ensuring that every new product that we release is accompanied with a complete, comprehensive GDTF file. Here is an example of the initial description for

The data inside the GDTF file provide many details, including...

Device description like name, RDM ID for identification by controllers, power consumption, picture, 2D vector image for planning tools, weight, power consumption and many more data, required for planning and pre-show calculations:

Screenshot metadata

3D model is provided in a way that clearly identifies each part of the device, including the base, cable connection panel, yoke, head and also for example the lens or lenses of the fixture, which, in case of for example the Spiider or Tarrantula, allows for very nice, realistic visualization.

Screenshot 3D model

DMX description contains all DMX modes, their identification via RDM and also their description for the operator, to be able to understand which DMX Mode is most suitable for their mode of operation.

DMX Mode

Included Color spectral power distribution data for lamps, LEDs, color flags and color wheels allow the controller to calculate DMX values for a particular color which a lighting designer is requesting. This also provides the possibility to select a desired spectral settings to not only achieve the perfect color but also it's spectral characteristic. This further allows to combine many fixtures of various manufacturers on a single stage and achieve the same color output from all devices (given that they provide GDTF with the spectral power distribution).

Screenshot spectral data

Graphics content of the GDTF files is including for example gobo images but also definitions for animation wheels, prisms and other effects.

The data contains many more details, for example speeds of movements or strobing frequencies, zoom ranges and so on.

This year, we have had many additions to our Robe GDTF files library (

If there is a fixture for which we do not provide a GDTF file or if you find an error in any of our files, feel free to contact us at a dedicated email address
