A9 smart lighting upgrade
Smart lighting with the IZYLUM and Schréder EXEDRA control system has improved safety and sustainability in Noord-Holland
The A9 motorway runs from Amsterdam to Den Helder in the coastal province of Noord-Holland and is one of the busiest in the country. It is managed by the Rijkswaterstaat West-Nederland Noord that aims to provide an integrated sustainable transport network to optimise connectivity and mobility in the northern Randstad region.
In 2022, Rijkswaterstaat decided to replace the 11,000 luminaires along this motorway and access roads (A7, N9 and N99) with energy-efficient LED lighting to improve safety and reduce its environmental impact.
Schréder worked with the contractor De Jong Zuurmond to provide a smart lighting solution that would enable Rijkswaterstaat to complete this large-scale project on time and achieve its objectives.
Sustainable lighting to keep the province on the move
The roads were lit by luminaires fitted with a mixture of low-pressure and high-pressure sodium lamps, but they were no longer providing the required lighting levels to ensure safety. We proposed the highly-efficient IZYLUM, which delivers quality light with low energy consumption to reduce costs and carbon emissions.
Rather than simply replacing the luminaires one by one, we decided to analyse the different roads to ensure an optimal lighting design that would improve visibility and therefore safety.

Application(s)
Each road falls into one of two types of ‘cases' that we have defined. For type 1 cases, we replace the luminaires with high-pressure sodium lamps on a one-to-one basis. For type 2 cases, where we replace the old fixtures with low-pressure sodium lamps, we review the lighting study, distances and poles to ensure an optimal lighting design.
The new lighting will enhance connectivity in the province by improving safety and accessibility which will in turn reduce journey times and foster economic growth.
Smart lighting for an optimised infrastructure
All of the new IZYLUM luminaires are fitted with Owlet IV nodes and connected to the Schréder EXEDRA smart lighting system. By adapting the lighting level to what is actually needed, Rijkswaterstaat will save even more energy and further reduce carbon emissions.
Schréder EXEDRA will also optimise the service life of the installation by quickly detecting any incidents and helping Rijkswaterstaat to anticipate maintenance, reducing operating costs even more.
A more circular lighting infrastructure
The IZYLUM luminaire was designed from the outset to contribute to a more circular economy. Not only is it made of recyclable materials (aluminium and glass) but it has been developed with tool-free access to the LED engine to facilitate maintenance and future upgrades with more advanced technologies.
This project is an important milestone in our efforts to ensure safety and sustainability in lighting infrastructure. We are making great strides towards a future where technologies and partnerships contribute to a more sustainable world.
A bright future for the new lighting infrastructure
The roll-out has been running smoothly, with over 4,500 luminaires replaced by March 2024, thanks in part to the easy mounting of the IZYLUM luminaire. The upgrade is expected to be completed by July 2024.
Reactions to the new lighting have been very positive and the Schréder EXEDRA platform has shown a 50% reduction in energy consumption, helping Rijkswaterstaat to achieve its sustainability objectives.
