The following review written by one of the Software Informer contributors applies to version 4.6
DIALux is a planning program for the presentation of projects.

By using this program, you will be able to plan the lighting you will use in a room, scene or building. The program will be able to calculate and visualize the daylight, as well as letting you plan your lighting scenes, plan the color and intensity of the lights you will use, position on the project the emergency lighting, with the right legal number of luminaires, and many more.

With DIALux you can prepare photo realistic visualizations of your light planning and send them to your customers via email, or upload them to a server.

For a better realism, the program can use different textures and furniture, and it uses an integrated ray-tracing module. You can also save your results in a .PDF format file, or export to .DWG and .DXF files. You can even import files in those formats to apply the lighting with DIALux.

The furniture, surfaces and luminaires can be placed simple dragging and dropping elements from the provided libraries.


  • It´s a complete and free tool to plan the lighting of any project.


  • None.
