About us

Seebacher GmbH is an owner-managed family-owned company and is known in the industry as an innovator for lighting control and building automation. Thus Seebacher was able to intelligently connect the worlds of building and stage lighting right from the start and was the first to use a touch control panel for building control in 1997. The first systems with monitoring and fault message processing were implemented by the company in the same year. Today, one of the topics of the future in the field of light is circadian lighting. Seebacher already introduced the DA-04VM module in 2000, which controls warm white and cold white luminaires circadian. In 2005, the IP interface, the integrated web browser and a mail client followed.

Business segments

Our business is essentially divided into two segments: The components business and the project planning of entire control systems. As part of the components business, we develop series-ready modules for integration into lighting and building control systems. From our work in projects new requirements and improvements arise again and again, which we incorporate into our series products.

During the project planning of systems we support our customers from the first cost estimate to the successful acceptance of the project. We provide advice, draw up a specification for the programming and, if required, commission the system. We will be happy to maintain the system regularly afterwards.

Our customers benefit significantly from the combination of both business areas, as the experience from developmentand practice flows together. Because we incorporate our experience from projects and the requirements of the market into product development. We can also provide optimum support for planners and electricians because we know our products as well as the back of our hand and offer good service.

What is important to us

In addition to earning the money we need for our salaries and for new and further developments of our products, the following points are important to us:

We want to have fun at work:

It is important to us that we enjoy our work. You spend a large part of your time in the company and it is important to us to spend this time with interesting tasks together with nice colleagues and pleasant customers.

We need the challenge:

Simple projects would sometimes be nice, but actually we love to solve challenges with professionalism and perfection. 

We want to impress with our projects:

With pride we want to tell our friends, acquaintances and customers that we have supplied the controls for projects such as the Sistine Chapel, the Hotel Adlon and many famous museums and churches in Germany and worldwide and that they also work to the fullest satisfaction of our customers.

We want to leave the world in good conscience to our descendants:

That's why we pay attention to sustainability, a long service life for our products and the implementation of systems with the highest level of comfort while saving as much energy as possible.

We want to have an honest, open and trusting relationship with our customers and partners:

We don't cheat or trick anybody. Our work is honest and comprehensible.

We want to be better than the competition:

Be it the quality we deliver or the technical know-how we have, we always want to be one step ahead. We strive for perfection and to offer our customers added value.
