Connected lighting in Jonava

Jonava runs a major residential zone on Lusety connected lighting with LIGHTWAVE and LIGHTWAVE-LTE luminaire controllers, LUMAWISE Motion sensors, LIGHT KEEPER cabinet controllers and the HORIZON platform, and consumes 65% less electricity than the static system it replaced.

Connected lighting in Jonava highlights how the city is using smart infrastructure to:

  • Improve safety
  • Cut energy waste
  • Reduce maintenance costs in residential areas.

 

Location:

Jonava, Lithuania

Software:

Urban lighting management platform HORIZON

 

The challenge

The zone was lit continuously through the night regardless of foot or vehicle traffic, which wasted energy, added light pollution and put avoidable strain on maintenance crews.

A major residential zone in Jonava required a lighting upgrade to meet modern safety, energy, and maintenance expectations. Previously, static lighting provided continuous illumination throughout the night, regardless of actual foot or vehicle traffic. This lead to unnecessary energy use, light pollution, and maintenance strain.

The city sought a smarter, more responsive system that could:

  • Ensure safety
  • Increase efficiency
  • And reduce the long-term costs of public lighting.

 

The solution: connected lighting in Jonava

The municipality fitted every luminaire with a controller and motion sensor, added LIGHT KEEPER cabinet controllers so the network stays reachable even when the lights are off, and connected everything to HORIZON.

The municipality deployed a full smart urban lighting ecosystem. They equipped each luminaire with motion sensors and controllers, thus ensuring the local network remained accessible at all times, not just during active lighting hours.

All components were connected to the urban lighting management platform HORIZON, which enables centralized monitoring, real-time data access, and remote control. Such a setup allows light levels to adapt automatically to real-time activity, brightening when pedestrians or vehicles are present and dimming during periods of low or no traffic.

 

Results & benefits

Electricity consumption and CO2 emissions fell 65%, HORIZON sends fault alerts as they happen, and fewer site visits cut maintenance costs by up to 30%.

  • Lighting adapted to real-life
    Lights respond to actual movement in the area, ensuring safety while reducing unnecessary brightness during quiet hours.
  • Energy efficiency and CO₂ reduction by 65%
    The adaptive system can reduce electricity consumption by up to 80%, helping the city lower both its energy bill and carbon emissions.
  • 24/7 network access
    With the cabinet and luminaire controllers, the lighting network remains fully accessible—even during daylight hours—allowing for round-the-clock oversight and data collection.
  • Fault alerts and predictive maintenance
    HORIZON sends instant notifications when faults occur, helping municipality crews resolve issues faster and avoid prolonged outages.
  • Lower maintenance costs
    Fewer site visits, smarter diagnostics, and reduced luminaire wear contribute to up to 30% savings in maintenance expenses.

 

Looking ahead

Jonava is now part of a smarter, safer, and more sustainable network of cities. By using real-time data and smart controls, the city is building a future-ready infrastructure that balances efficiency with quality of life for its residents.
