Retrofit Solutions Lighting technology is rapidly evolving. Even though our luminaires are developed to last a minimum of 20 to 25 years, some luminaires installed ten years ago are already outdated in terms of their electronic components, yet their housing is still in good condition. To solve this problem, we have developed various retrofit solutions (photometric and electronic) that can be installed in existing luminaires. This enables towns and cities to benefit from the latest technologies at a reduced environmental cost as only the obsolete components need to be replaced. Retrofitting offers a sustainable solution in a situation where a luminaire can last for more than 15-20 years. Giving the luminaire a second life also preserves the urban landscape. LED retrofits not only save energy and maintenance costs, they also save on materials. In a retrofit, much of the luminaire is reused and the rest is sustainably recycled.
Remanufacturing Remanufacturing is the process of restoring a used product to the specifications of the original manufactured product using a
Smart Tunnel Lighting Ensures Safety and Preserves Heritage in the Maastunnel
Opened in 1942, the 1,373m-long Maastunnel was the first immersed tunnel in the Netherlands and Europe. The tunnel crosses the Nieuwe Maas River that flows through the heart of Rotterdam. An average of 75,000 motorists now use the tunnel every day.
combination of reused, repaired and new parts. It is a sustainable way to preserve resources, reduce environmental impact and waste. Our factories in Hungary and France have started their first remanufacturing projects, where existing luminaires are recovered and upgraded to near-new condition, including the latest efficiency technologies. Initiatives such as these contribute to our goal of maximising the lifespan of existing lighting equipment while reducing its environmental footprint.
Thanks to its place in engineering history as the first immersed tunnel, the Maastunnel was classified a National Monument in 2012. This meant any renovation work had to respect the original features and ensure that the “look and feel” were preserved. In the 1940s, sodium lighting, with its warm orange glow, was the norm. We proposed an original smart tunnel lighting solution to meet both requirements and carried out a pilot project to show the local authorities how it would work. We fitted some of the existing luminaires in the tunnel, which were still in good working condition, with amber and white LEDs. The amber LEDs light the tunnel during normal operating hours. The luminaires are controlled by an ATS/Lumgate Controls system which switches on the white LEDs if an incident occurs and the emergency services need access. By combining both types of LEDs, the lighting respects the safety standards while preserving the tunnel’s character. The local authorities were delighted with the results of the pilot project. In total, 760 of the existing luminaires in the tunnel were retrofitted with the new amber/white LED optics and almost 380 new GL2 COMPACT luminaires were installed.
