From Always-On to On-Demand Lighting: What France’s Smart Street Lighting Pilot Means for Cities

Introduction

Public street illumination has followed a simple operative principle for decades: lights robotically switch on at sunset and remain illumined until dawn. Road security, pedestrian visibility, and nighttime security has improved because of this approach, but at the same time it also means that thousands of luminaires continue functioning even when streets are empty.

Rising electricity costs, determined carbon reduction targets, growing awareness of light pollution, and speedy advances in digital technology are encouraging municipalities to rethink how public illumination should operate.

One of the most innovative examples comes from Loos-en-Gohelle, France, where a pilot project called “J’allume ma rue” (I Light Up My Street) was launched on June 9, 2026. Istead of  leaving lights on all through the night, the city substituted its whole street illumination network with LED luminaires and adopted an on-demand lighting strategy.

This project represents much more than a local energy-saving initiative. It shows an extensive evolution in Adaptive Street Lighting, On-Demand Lighting, Smart Street Lighting, Public Lighting Control, Smart Photocell, and Zhaga Book 18 technologies that are redefining how municipalities balance sustainability, operational proficiency, and public security.

Why Are Cities Rethinking Traditional Nighttime Lighting?

Traditional street illumination has served municipalities well for decades, but it was developed during an age when electrical energy was comparatively cheap and illumination systems offered little operative flexibility.

Many inhabited streets experience very little activity between night-time and early morning. In spite of nominal pedestrian or automobile traffic, illumination systems continue operating at full glare, using electricity whether anyone is present or not.

Cities gradually recognize some challenges associated with traditional illumination:

• needless overnight energy usage
• increasing electricity bills
• growing maintenance expenses
• too much carbon emanations
• light pollution
• abridged visibility of the night sky
• needless operating hours that shorten equipment lifecycle

All at once, completely switching lights off creates reasonable public concerns.

Citizens may worry about:

• personal security
• pedestrian visibility
• emergency access
• crime deterrence
• neighborhood safety

The challenge is no more simply reducing electricity usage.

This is where On-Demand Lighting starts changing the conversation.

How Does On-Demand Lighting Create a Better Balance?

Instead of treating illumination as either fully ON or completely OFF, demand-based systems introduce a far more flexible functioning model.

Illumination becomes available exactly when required.

France’s pilot exhibits this concept efficiently.

During chosen nighttime hours, lights remain off to eradicate needless electricity usage.

Though, if residents need lighting while walking home, cycling, exercising, or accessing public facilities, they simply activate neighboring illumination through a Smart Lighting App.

The illumination remains operative for a predefined period before automatically returning to standby mode.

This approach brings numerous important benefits.

First, energy usage falls considerably because luminaires operate only when people are actually present.

Second, citizens retain confidence knowing illumination remains immediately available.

Third, cities evade the political and social concerns often linked with permanent nighttime shutdowns.

This signifies a major move from always-on infrastructure toward responsive infrastructure.

Which Lead-Top Solutions Support Intelligent On-Demand Lighting?

Successful adaptive illumination projects rely on dependable illumination control components skillful of supporting future smart infrastructure.

Lead-Top offers solutions specifically designed for connected outdoor lighting applications.

Together, these products support cities transitioning from orthodox illumination toward fully connected Smart Street Lighting systems. 

Instead of viewing illumination exclusively as public lighting, cities increasingly consider illumination networks as smart urban platforms skillful of adapting to changing communal needs.

Though each city will choose different implementation strategies, the extensive direction is clear.

Illumination is becoming:

• responsive
• connected
• data-driven
• citizen-focused
• ecologically responsible

Frequently Asked Questions

Conclusion

France’s innovative “J’allume ma rue” initiative shows how public illumination is growing from static infrastructure into smart urban services. Cities are embracing On-Demand Lighting and Adaptive Street Lighting strategies that deliver light exactly when and where it is required, rather than depending on permanent nighttime lighting,.

This approach helps municipalities address numerous priorities at the same time: decreasing energy usage, minimalizing light pollution, dropping operating costs, and upholding public confidence in nighttime security. As illumination networks become increasingly connected, technologies such as Smart Photocell controls, Public Lighting Control platforms, and Zhaga Book 18 interfaces offer the flexibility required for future smart city development.

Cities are building smart illumination ecosystems that can evolve together with varying urban needs, instead of simply substituting older luminaires with LEDs,. The changeover from “always-on” to “on-demand” illumination marks a noteworthy step toward more sustainable, citizen-focused, and digitally connected municipalities.
