The city of Arnsberg and the larger area around Arnsberg is and has been the center of the German and International lighting industry for a long time. It goes back to the time before electricity was available, to the time of the petroleum lamps around 1830. A significant number of factories producing petroleum lamps and parts started in the Arnsberg Stadtteil of Neheim. With electricity becoming available after 1890, the factories adapted and started to make electric lighting fixtures and lamps. The most famous factory was the Kaiser factory, which already in the twenties and thirties of the last century provided lighting fixtures and lamps to a worldwide market.

Today, some of the largest lighting companies still call Arnsberg home. It is also home of the Lichtforum NRW (Nordrhein Westfalen), as well as the home for the Museum for Licht (Museum fuer Licht und Beleuchtung).

It is in this environment that Bernd Mueller started Trio in 1991. His main focus was always to bring the latest in Lighting Technologies as well as the latest Lighting Trends to the European market. He built his company from small beginnings to one of the leading German and European Lighting companies with more than 170 Employees and sales in Excess of one hundred million U.S. Their success is not only based on providing the latest trending lighting fixtures and lamps in a timely fashion to the marketplace, but also to be able to provide substantial technological lighting improvements, for example through the cooperation with Osram of Munich, Germany, to provide better and consistent LED Lighting through proprietary LED modules or through cutting edge dimming and switching technologies. He is now aided by his son Philipp to keep the company on a prudent growth path.

In 2016 the Mueller family and Paul W. Eusterbrock and his family joined forces to form ArnsbergerLicht, Inc., doing business as Arnsberg, to honour the long lighting tradition that the new enterprise is the result of. Paul W. Eusterbrock, a native of Germany has more than 30 years of lighting experience in the US. He is a former Chair of the American Lighting Association and has spent a significant amount of time working with the University of Colorado at Boulder to research the issue of Lighting for the Aging Eye. Both, the quality of light and the quality of the lighting fixture are important to him. Also, a significant number of patents in the lighting industry were awarded to him. 

The mission of the new company is to bring you the best lighting available at an affordable price. Also, our goal is to continually raise the design and technical quality standards, resulting in the best value proposition for you, our customer. The continual development of new technologies and new lighting solutions is part of the Arnsberg DNA and also our goal. Arnsberg as a company will continue to develop and distribute Trio products, but also other Zeitlos products as time goes on.

Thank you for your consideration
