With rapid urbanization, cities are under pressure to optimize resources and provide enhanced services. Street lighting controls are at the forefront of this change.

Light control technology plays a crucial role in the development of smart cities. By enabling real-time monitoring and automated adjustments of lighting systems, this technology makes public lighting efficient and contributes to sustainability.

This article explores the integration of street light controllers in five cities—Barcelona, Singapore, Toronto, Vienna, and Florence—highlighting the diverse benefits these technologies bring to urban development.

Barcelona Case Study

Barcelona stands as a global example of how smart city technologies can improve urban living. One of its torch-bearer projects is its intelligent transportation systems (ITS) and light control technologies.

Since 2016, Barcelona has been using a centralized control platform for public lighting. This is designed to monitor and manage energy consumption and maintenance in real-time. Rather than simply increasing light output, Barcelona focuses on optimizing light distribution across its 146,000 lighting points. This approach improves visibility without wasting energy.

Currently, more than 50% of the city’s lighting system is remotely controlled. These efforts have led to a significant reduction in energy consumption, with the city adhering to international standards that recommend light levels between 5 and 30 lux for safety.

Its operation involves synchronizing street lighting with transportation networks, which helps adjust illumination levels based on traffic density, pedestrian activity, and weather conditions.

This responsive lighting improves visibility in high-traffic zones during peak hours, reducing congestion-related accidents and enhancing safety for both drivers and pedestrians.

Singapore Case Study

Singapore is equipping over 110,000 street lamps with a Remote Control and Monitoring System (RCMS). By completing the project in 2025, Singapore is all set to lead the way in smart urban lighting.

This initiative, which began in 2023, allows the city to automatically adjust lighting based on weather and time. This ultimately results in substantial energy savings. The RCMS is set to cover 350 kilometers of walkways and cycling paths, along with numerous bus stops and taxi stands​.

Since its implementation, the system has saved approximately 8.75 million kilowatt-hours (kWh) annually, enough to power around 2,000 four-room flats. Additionally, the RCMS enhances maintenance efficiency by detecting faults and notifying staff, which has led to an 80% reduction in public complaints.

As Singapore continues to innovate its lighting systems, the focus remains on sustainability and improved urban living standards.

Toronto Case Study

In Toronto, the integration of advanced networked infrastructure with street light controllers has significantly elevated urban lighting intelligence. The city leverages IoT-driven smart lighting technology, enabling real-time monitoring, adaptive lighting, and centralized control.

These street lights, designed in the form of LED having inbuilt sensors, automatically change the illumination levels in response to environmental changes such as traffic presence, weather conditions and more, ultimately enhancing security as well as saving energy.

This interconnected infrastructure also aids in predictive maintenance, where potential outages are detected early, reducing system downtime.

By adopting these technologies, Toronto positions its street lighting as a platform for broader smart city initiatives, such as enhancing connectivity and public safety. Additionally, the ability to scale this system supports the city’s sustainable development goals through reduced energy consumption and emissions, promoting a greener urban environment.

Vienna Case Study

Vienna is a leading example of green city construction under green public procurement (GPP) standards. The city has implemented the “EcoBuy Vienna” program, which emphasizes energy-efficient and environmentally conscious purchasing.

Vienna has integrated sustainable procurement across sectors, including urban lighting. The outcomes of this integration are lowered energy consumptions, longer product life cycles and a drastic reduction of carbon emissions. Further these efforts align with Sustainable Development Goals (SDGs), particularly SDG 12, focused on responsible consumption and production​.

Improving energy efficiency by using street light controllers also lower maintenance costs and contribute to the reduction of light pollution. Through GPP initiatives, Vienna sets rigorous standards for procuring lighting systems that meet energy-efficiency criteria, ensuring that urban development aligns with climate protection goals.

Vienna’s approach demonstrates how integrating light control technologies with green procurement practices can create a more sustainable, low-carbon urban environment, supporting the city’s ambition to become a role model in green city development.

Florence Case Study

In Florence, the integration of light control technology plays a significant role in its green city initiatives. Through the REPLICATE project, the city has implemented a smart lighting system based on energy-efficient LED technology.

These lights are equipped with sensors that gather environmental data, such as traffic and air quality, contributing to broader smart city operations. With smart LEDs, Florence has achieved over 40% in energy savings, 2.2 Million Euro, 3000 tonn reduction of carbon dioxide emission, while also reducing light pollution and enhancing public spaces.

Further Florence’s Smart City Control facility coordinates multiple city services, including lighting, traffic, and public transportation. It allows the city to dynamically adjust lighting levels based on real-time data. These efforts align with Florence’s green purchasing standards, aiming to promote sustainability while meeting environmental targets.

This holistic approach to lighting and smart technology positions Florence as a leader in combining energy-saving innovations with urban infrastructure management.
