Special workmanship from Thuringia - Made in Germany.
Sondershausen is a legendary mining town that today is the site of Germany’s oldest and deepest working potash mine. What’s more, the renowned Loh-Orchester and prominent cultural figures such as Franz Liszt and Max Bruch are inextricably linked with Sondershausen and remain to this day an important part of the city’s heritage.
We’ve been a fixture of Sondershausen for more than 30 years now.
Back in the 1970th the VEB Elektroinstallation produced luminaires at this location. In 1992 Dr. -Ing. Alexander Zimmermann bought the luminair production part of VEB Elektroinstallation and founded the company SONLUX. Since that time we have been producing high-quality and efficient luminaires for industry, trade, authorities and organisations with security tasks as well as event organisers. Since then, the plant, technologies and product range have been continuously expanded. Today, around 130 employees develop and manufacture the SONLUX quality portfolio on 25,000 square meters production area.
"Portable light for professionals" – Innovative premium products with an excellent price-performance ratio.

The fall of the Berlin Wall
In the period of political turn-around, the former sub-states reunited. At the same time, VEB Elektroinstallation and RZB made initial efforts to further expand their cooperation.

Before reunification
VEB Elektroinstallation Sondershausen in Thuringia.
Close co-operation with RZB Leuchten Bamberg had already existed since this time, which laid the foundation for the later merger of the two companies.

Foundation of the company
On 16 November 1992, 70 former employees of the former state-owned company VEB Elektroinstallation began manufacturing lights in the newly founded SONLUX GmbH & Co. KG with the production of lights.
Dr Alexander Zimmermann, sole shareholder and managing director of the company RZB in Bamberg, had acquired this part of the business from the Treuhand at the beginning of the month. He knew the location and the products. His father, the founder of RZB, had already been sourcing lights from Sondershausen long before reunification.
The final entry in the commercial register was made in May 1993.
