Why simplicity matters in smart lighting

Cities face growing pressure to improve sustainability, public safety and service delivery, with technology often expected to provide the answer. Yet the systems underpinning smart city initiatives can themselves introduce new layers of complexity.

 In this Q&A, Julia Arneri Borghese, CEO of Paradox Engineering, explains why simplicity has become a guiding principle for smart lighting projects, and how open, interoperable systems can help cities deploy and expand connected infrastructure without adding unnecessary operational burdens.

What does simplicity mean in the context of smart lighting, and why has it become such an important issue for cities?

Cities are confronted with a number of urgent and complex issues which span ordinary as well as extraordinary matters: traffic, service efficiency and quality of life, environmental sustainability and climate resilience, public safety and social inclusion, and financial stability to name a few. Technology must allow city leaders to focus on these priorities and the wellbeing of their communities, without spending time and money in unravelling the unnecessary complexity of the very technical infrastructure which should simplify their work.

That’s why simplicity is more than just a keyword for us. It is about designing and delivering smart lighting solutions that are truly effortless to install, integrate, and operate, requiring the minimum possible maintenance. For cities to thrive on lighting as the backbone for urban innovation and growth, technology providers like us must solve the equation between advanced, feature-rich products and streamlined ease of use: complexity has high hidden costs, and it is our duty to spare our customers from it.

Smart lighting is often perceived as complex and difficult to implement. What are the biggest challenges cities face when planning and deploying smart lighting infrastructure?

From a technical perspective, a smart lighting system is an advanced Internet of Things (IoT) network that combines luminaires, lighting controllers, additional sensors, multiple communication protocols, and a central management software. All these elements must interact seamlessly in real-time but, depending on the specific layout and urban topography of each city, even ensuring reliable connectivity can introduce a first, significant baseline of complexity.

Another relevant challenge lies in integrating new technologies with the city’s legacy network. Nowadays, municipalities often ask for extending or modernising an existing infrastructure: bridging the gap between old and new without disrupting public services or overcomplicating day-to-day operations is a delicate balancing act that many cities find difficult to navigate, especially if chosen solutions were not designed with the future in mind, ready to follow the evolution of technology and mindset.

Interoperability and vendor lock-in are growing concerns for municipalities. How important are open and flexible systems in helping cities build smart lighting networks that can evolve over time?

They are absolutely critical. Street lighting infrastructure is a long-term capital investment designed to last for decades. If a city selects a proprietary, closed ecosystem today, operational agility and future innovation may be compromised.

Simplicity is tied to flexibility and freedom. By adopting open standards and truly interoperable systems, municipalities eliminate the risk of vendor lock-in. It means a city can seamlessly integrate new devices or launch a new urban application without undergoing an expensive system overhaul. Decisions made today must be able to withstand decades of technological evolution, and open standards ensure the network stays scalable enough to grow alongside the community.

Street lighting projects typically involve multiple stakeholders, from city departments and utilities to technology providers and contractors. How can cities simplify collaboration and decision-making across these groups?

Making life simple for cities requires providers to absorb part of the natural complexity engrained in complex and articulated scenarios. Street lighting naturally intersects with city councils, technical departments, utilities, power and connectivity providers, system integrators, and third-party installation and maintenance crews. When designing smart lighting solutions, our goal is to address the pain points of each stakeholder; we support with a full range of professional services for city and utility managers throughout the planning, designing, and installation phases, as well as with technical assistance and troubleshooting during implementation and maintenance, and solid project management throughout all phases of the projects.

Many cities want to use lighting infrastructure as a platform for wider smart city applications. How can they expand capabilities without adding unnecessary complexity?

Street lighting is the ideal urban backbone for urban innovation because it is widespread and already powered. Of course, hosting multiple city applications–like traffic monitoring, environmental sensing, or parking management–on the same network is possible only if the infrastructure is interoperable and based on open data models. If so, when the city wants to add new sensors for environmental monitoring or new systems for public safety surveillance, it can simply plug it into the existing network. The infrastructure expands and evolves, but the backbone remains exactly the same.

From installation and commissioning to ongoing operations and maintenance, where do you see the greatest opportunities to simplify the management of smart lighting networks?

We call it ‘simplicity by design’. We look at the entire lifecycle of a smart lighting solution and strip away any unnecessary complexity at every phase. For instance, we focus heavily on ready-to-use, plug-and-play hardware, so that new smart lighting points can be installed quickly and immediately operated. We drastically simplify operations such as auto-commissioning, auto-inventory, over-the-air firmware update.

We rely on open data models to allow full interoperability with any management platform, so our customers can perform tasks like scheduling adaptive lighting patterns or analysing energy consumption through their preferred software management system.

What practical advice would you give to cities that are beginning their smart lighting journey and want to achieve long-term benefits?

Our advice is to think big but start simple. It doesn’t pay off to plan hyper-complex smart city blueprints. As per our experience, it is far more effective to begin with targeted street lighting projects to achieve measurable objectives such as energy efficiency, reduced maintenance, and public safety.

In the long run, there are two success-critical aspects: interoperability, enabling multi-vendor upgrades over time, and cybersecurity, minimising vulnerabilities and having the best possible defence against potential cyberattacks.
