Cities everywhere are under pressure to do more with less — modernize aging infrastructure, improve public safety, cut energy costs, and meet sustainability goals. One of the fastest, most cost-effective ways to make progress on all of these fronts isn’t a new technology at all, but a smarter version of something every city already has: its streetlights. Smart lighting is transforming these ordinary fixtures into connected, data-driven assets that can help cities save money, enhance safety, and build the foundation for future smart-city innovation.
What began as a simple transition from high-pressure sodium lamps to LEDs has evolved into a sophisticated network of sensors, controls, and analytics that adapt in real time to the needs of modern urban environments. Smart lighting is reshaping how municipalities, utilities and planners think about energy management and infrastructure — and ultimately redefining the role of illumination in a rapidly changing world. Envocore will discuss.
What Is Smart Lighting?
Smart lighting refers to network-connected lighting systems that go beyond simple illumination. These systems typically involve LED streetlights equipped with smart nodes or controllers that communicate with a central management platform. They can adjust brightness levels automatically based on ambient light, traffic, weather, or programmed schedules. Some smart lights are paired with additional sensors, such as motion detectors, cameras, or environmental monitors, that allow them to serve broader urban functions, including traffic management, air quality monitoring, and public safety surveillance.
Smart lighting is not just about better light; it’s about better information and control. With remote management capabilities and two-way communication, these systems allow cities to monitor outages, respond quickly to maintenance needs, and analyze performance across entire grids.
Energy Efficiency & Cost Savings
Perhaps the most compelling reason cities adopt smart lighting systems is their potential for significant energy and cost savings. Traditional streetlights are often left on all night at full brightness regardless of need. Smart LED systems, in contrast, can dim during low-traffic hours or when conditions don’t require full illumination.
According to the US Department of Energy, by 2035, the majority of lighting installations are anticipated to use LED technology. Energy savings from LED lighting could top 569 TWh annually by 2035, equal to the annual energy output of more than 92 1,000 MW power plants.
Beyond kilowatt-hours and dollars, smart systems offer improved asset tracking and lifecycle management. Real-time diagnostics mean cities can proactively address faults before they become public complaints, optimizing labor and extending equipment life.
Enhancing Public Safety Through Light & Data
Well-lit environments have long been associated with safer streets, but smart lighting takes that a step further. Adaptive lighting levels can be increased in response to motion, enabling better visibility in pedestrian-heavy areas or during emergency responses.
In high-risk locations like intersections, parks, or public transit stations, smart lights can work in tandem with sensors and surveillance systems to deter crime, assist in investigations, and even alert authorities to abnormal behavior.
A 2024 study published in Buildings emphasizes that enhanced street lighting — especially with strategic design — can reduce both actual crime rates and perceived risk in built environments. This aligns with Crime Prevention Through Environmental Design (CPTED) principles and offers quantitative lighting recommendations to improve safety.
Lowering Maintenance Costs With Predictive Insights
Smart lighting also transforms how municipalities manage and maintain lighting infrastructure. Traditional streetlight maintenance is often reactive, relying on residents to report outages and crews to conduct manual inspections. Smart systems, by contrast, provide real-time alerts when a lamp fails, a controller malfunctions, or voltage drops unexpectedly.
This ability to predict and prevent failures can significantly reduce maintenance costs. Asset tracking features can help cities avoid redundant replacements and reduce inventory waste. Maintenance crews can be deployed more efficiently with detailed insight into exact problem locations and component specifications, saving time and money.
Building the Backbone of Smart Cities
Smart lighting is more than a standalone upgrade — it can provide a foundation for a city’s broader smart-infrastructure strategy. Once a city equips its streetlights with wireless connectivity and power at every pole, those same poles can support much more than lighting. They can host traffic sensors, air-quality monitors, EV-charging indicators, security devices, or even public Wi-Fi.
This creates a scalable framework for future innovation. What begins as a basic LED or controls retrofit can grow into a citywide network capable of supporting advanced smart-city applications. When lighting is integrated with municipal IoT platforms, cities can gain a unified view of how people move, how energy is used, and where infrastructure needs improvement. Cities like San Diego, Barcelona, and Copenhagen have already shown how intelligent streetlights can function as backbones of modern urban systems, connecting data, devices, and services across communities.
Equity, Access & Environment
Smart lighting also plays a role in addressing broader urban priorities. Dimming lights in low-traffic areas helps reduce light pollution, preserving night skies and reducing ecological disruption. Adaptive lighting strategies also allow for more equitable distribution of resources, ensuring that underserved neighborhoods receive appropriate attention, visibility, and safety enhancements.
Some cities are using smart lighting data to inform zoning decisions, identify underserved areas, or plan pedestrian-friendly corridors. In this way, lighting becomes not just a utility but a policy tool—helping align public infrastructure with environmental, social, and economic objectives.
Implementation Considerations for Municipalities
While the benefits are clear, successful smart lighting deployments require thoughtful planning. Cities must consider not just the hardware and software, but also long-term support, data ownership, cybersecurity, and integration with existing infrastructure. Stakeholder alignment is key. Transportation departments, IT staff, public safety teams, and sustainability offices must work together to define goals and select technologies that align with municipal priorities.
Pilot programs can provide valuable insights, allowing cities to test system performance, refine policies, and gather public feedback before scaling. Choosing a vendor with experience in large-scale municipal deployments is deeply important — particularly one familiar with smart lighting, distributed sensor networks, and related technologies such as AMI or utility metering systems, which often share similar communication and integration requirements.

Real-World Impact: Cities Leading the Way
Cities across the U.S. have already embraced smart lighting with notable results. In Louisville, KY, Envocore helped the city with lighting upgrades in the City’s Zoo, Parks, Police, and Library Departments. The kW and kWh were reduced by 22 percent and 25 percent respectively. The four departments expect to realize over $180,000 in annual savings. The maintenance savings were also significant. The upgraded lighting systems will see an increase in lamp life ranging from 20,000 to 30,000 hours for linear fluorescents; 20,000 to 50,000 hours for HID to LED; and 2,000 to 25,000 hours for incandescents to LED. The case study shows that smart lighting, properly planned, can provide a cost-saving measure and serve as a launch pad for smarter, safer, more sustainable communities.
The Road Ahead: Intelligent Illumination for Smarter Cities
As technology continues to evolve, the conversation on lighting in urban infrastructure and the possibilities continues. Future systems may include lights that respond to emergency vehicles, communicate with autonomous cars, or adapt to seasonal pedestrian patterns. What remains constant is the need for efficiency, resilience, and public trust. Smart lighting can offer a rare alignment of interests. It can save money, reduce emissions, improve public safety, and enable long-term innovation. For cities grappling with aging infrastructure and rising demand, smart lighting can serve as a smart investment.
