Adaptive lighting in Sakiai

Sakiai runs adaptive residential lighting from Lusety on LIGHTWAVE and LIGHTWAVE-LTE luminaire controllers, LUMAWISE Motion sensors and the HORIZON platform, with electricity use and CO2 emissions both 84% lower than before.

Adaptive lighting in Sakiai illustrates how smart technology can make residential areas safer, more energy-efficient, and environmentally friendly.

The challenge

The residential area in Sakiai was lit on fixed schedules that held luminaires at a moderate level all night regardless of activity, which wasted energy, added maintenance load and produced avoidable light pollution.

A calm residential area in Sakiai needed a lighting upgrade to improve both safety and sustainability. The existing lighting system operated on fixed schedules, keeping luminaires moderately lit throughout the night regardless of actual activity. This led to wasted energy, increased maintenance demands, and avoidable light pollution.

To support its smart infrastructure goals, the city looked for a lighting solution that could respond to real-time usage while reducing long-term operational costs.

 

The solution: adaptive lighting in Sakiai

Sakiai installed motion sensors and luminaire controllers across the residential zone and integrated them into HORIZON, so luminaires stay dimmed during quiet hours and brighten when a pedestrian or vehicle is detected.

Sakiai deployed a full smart urban lighting ecosystem by installing motion sensors and luminaire controllers across the residential zone. All components were integrated into the HORIZON urban lighting management platform, giving the city full yet remote access and control of its lighting infrastructure.

The true adaptive lighting technology enables luminaires to remain dimmed during quiet hours and automatically increase brightness when pedestrians or vehicles are detected, ensuring comfort, safety, and efficiency based on actual movement in the area.

 

Results & benefits

Electricity use and CO2 emissions fell 84%, and reduced wear on the luminaires brought maintenance costs down by up to 30%.

  • Real-time, behavior-based illumination
    The lighting system adapts instantly to motion, brightening only when activity is detected and dimming again when the area is empty.
  • 84% less energy consumed and CO2 emitted
    With adaptive dimming, the city can reduced its electricity use and CO2 emissions by 84%.
  • Minimal light pollution
    Reduced unnecessary lighting creates a more comfortable nighttime environment for residents while preserving the night sky.
  • Centralized control and visibility
    Through the HORIZON platform, Sakiai’s operators can monitor illumination status, adjust settings, and access live data for better planning and maintenance.
  • Smarter infrastructure with lower costs
    Less wear on luminaires and fewer on-site interventions help reduce maintenance costs by up to 30%, contributing to long-term sustainability and operational efficiency.

 

Looking ahead

By implementing adaptive lighting in residential areas, Sakiai is laying the foundation for smarter, more efficient urban infrastructure. This project highlights how data-driven lighting can simultaneously improve quality of life, reduce environmental impact, and optimize city resources.
