DIAL – We develop DIALux, the worldwide standard in lighting design software but we do even more

DIAL was founded in 1989 as the German Institute for Applied Lighting Technology (DIAL) and since then has offered a wide range of expertise in the field of lighting design and building automation. Since 1994, the focus has been on the development of DIALux – the world's leading lighting design software.

We believe that good software and usability, contribute to an easier lighting design that is fun – and even free for the user. It is important to us to make the designer's work easier and to offer luminaire manufacturers an optimal platform with which to market products professionally and in a target-group-oriented manner. We employ enthusiastic software, lighting and smart building planners who deal with issues relating to lighting and intelligent buildings on a daily basis and share their knowledge in seminars.

Our portfolio


With DIALux we are the market leader in the field of light planning software. More than 750,000 professional users worldwide – including engineers, electricians and lighting designers – plan, calculate and visualize light with our software. At the same time, more than 190 renowned lighting manufacturers offer their products for planning in DIALux. DIALux is therefore not only a lighting design software, but also a marketing tool for luminaire manufacturers.


We provide knowledge in the fields of DIALux, lighting and smart building. With us you can book seminars on site or online seminars.  These include seminars at our headquarters in Lüdenscheid, Germany, as well as training sessions with certified DIALux trainers around the world.
