We ensure safe routes and power supplies in emergency situations.

Escape and rescue routes should be immediately visible and clearly identifiable for people in emergency situations. Power supplies vital to the system must not fail, even if the network is interrupted. We develop, produce and market photoluminescent and electrical guidance systems and signage for security applications in buildings, aviation and shipping. We plan and supervise projects in the field of industrial and secure power supplies throughout the entire product life cycle, from development to service & maintenance.

Over 25 years dedicated to safety

The development and optimization of security products is one of our central goals. We always look at the big picture and can therefore offer our customers comprehensive service, ranging from consultation and product development to service and maintenance. Our team of 60 employees ensure that our products are developed, produced and optimally used in accordance with the highest standards. The PERMALUX corporate culture means that we work hand in hand across departments and always focus on the optimum safety system for our customers. We are committed to launching innovative products on the market and to being a reliable and trustworthy partner for our customers.

Products for your safety

We offer our customers complete and complementary products and services for the safety equipment of buildings, ships and aircraft.

Ever since it was founded, the name P.E.R. has stood for Permalux Escape Routes. This describes our philosophy of manufacturing products that provide permanent lighting even in emergency situations and ensure an energy supply to enable people to escape safely. The PERMALUX logo contains the various products and services of the company: the stripes of the "E" represent our floor guidance system, the "LUX" stands for the light of the safety lighting, "PERM", an abbreviation for "permanent", is symbolic of the emergency power supply. The new PERMALUX brand presence revives and continues the successful guiding principle taken from P.E.R.'s company history.

Competence and experience result in certified quality

"Look, we'll argue about everything else, but when it comes to quality, we're not going to fight each other. Quality cannot get mixed up with other bargaining and be compromised by the unusual adversarial relationship between workers and management." (Lee Iacocca). We always follow this statement and act in the interests of our customers.


We are an active member of various professional associations and are thus involved in shaping standards. In this way, we ensure that the latest specialist knowledge is always incorporated into our products and that we can offer our customers optimum solutions for their needs.
