As part of its bold climate and energy goals, the European Green Deal is reshaping infrastructure development across the continent. Among the major focus areas? Urban lighting. Cities are now fast-tracking the upgrade of their aging sodium street lamps to LED-based, energy-saving smart solutions.
Across Germany, Spain, the Netherlands, and France, municipalities are issuing public tenders that emphasize:
- Energy efficiency through LED retrofits
- Remote monitoring via connected lighting controls
- Modular design to support future upgrades
At the core of this revolution is Zhaga Book 18, a universal standard that makes interoperable lighting systems possible, It ensures that controllers, фотоэлементы, and smart sensors from different manufacturers can work seamlessly together.
“Zhaga Book 18 is now a must-have for any smart streetlight tender in the EU.”
— Lighting Engineer, Brussels City Council
What Are the Problems with Proprietary or Legacy Streetlight Interfaces?
Historically, outdoor lighting relied on basic photocells or custom controller interfaces that created serious limitations:
- Proprietary sockets that blocked upgrades
- Basic dusk-to-dawn фотоэлементы with no networking capabilities
- Poor IP protection (IP44–IP54) unsuitable for outdoor European environments
These solutions fail to support evolving smart city requirements, making it difficult to:
- Retrofit dimming/sensing devices
- Integrate with CMS (Central Management Systems)
- Meet EU interoperability and circular economy goals
Issue | Impact on Modern Projects |
Incompatibility | Can’t integrate with smart sensors or CMS |
High Maintenance | No remote diagnostics → more on-site visits |
Limited Functionality | Only dusk-to-dawn, no dimming/scheduling |
Regulatory Non-Compliance | Fails to meet circular economy standards |
Whether it’s retrofitting dimming capabilities or deploying remote control lighting, outdated photocell setups simply can’t keep up.
Zhaga Book 18: The New Standard for Smart Lighting in Europe
Zhaga Book 18 is a standardized 4-pin interface developed by the Консорциум Жага for mounting intelligent controllers and sensors directly onto LED street luminaires.
It supports low-voltage (24VDC) operation and is compatible with advanced smart technologies like:
- Plug-and-play sensors, including фотоэлектрические датчики, motion detectors, and environmental sensors
- Multi-brand interoperability, ensures that a photocell switch from one vendor can work with a socket from another
- Modular architecture, allows lighting to be upgraded as tech evolves
- EU policy alignment, promotes long-term sustainability and digital connectivity
With a Zhaga socket, you can transform a streetlight into a smart node in a city-wide lighting control network, enabling plug-and-play integration of sensors, remote monitoring, adaptive dimming, and future upgrades without replacing the entire luminaire.

Real-World Application: Amsterdam’s Lighting Upgrade Initiative
Amsterdam recently launched one of Europe’s largest smart lighting overhauls, replacing over 20,000 sodium lamps with Zhaga-compatible LED luminaires using Lead-Top’s LT600 Series.
- Energy consumption reduced by 45%
- Real-time data collected from photocell sensors and motion detectors
- Maintenance dropped significantly thanks to remote diagnostics
Now, similar initiatives using photocell lighting sensors are being adopted in:
- Vienna, Austria
- Munich, Germany
- Rotterdam, Netherlands
Each deployment leverages the plug-and-play capability of Zhaga Book 18 to scale smarter, faster, and with less labor.
Why European Clients Choose Lead-Top?
With more than 20 years of manufacturing experience, Zhejiang Lead-Top is a leading photocell sensor manufacturer serving public and private clients across Europe.
- Full Zhaga Book 18 compliance
- DALI-2, NB-IoT, and 0–10V controller variants
- OEM/ODM services with customized labeling and specs
- Fast delivery from 15,300㎡ factory to EU logistics centers
- Low MOQ flexibility for pilot or city-scale projects
- Customized solutions with CE certification
From photocell street light controllers to modular outdoor light sensors, Lead-Top’s systems are trusted by municipal engineers and large-scale contractors alike.

The Importance of IP66+ in Europe:
While Zhaga compatibility is critical, IP rating is just as important, especially in Northern and coastal Europe, where weather is harsh.
- Rain and snow can damage unsealed housings
- Fog and salt air (e.g., UK, France, Netherlands) cause corrosion
- Dust and insects can degrade non-IP-rated controllers
Lead-Top’s IP66 enclosures protect the core photocell components and sensor electronics, ensuring 10-year performance guarantees even in extreme climates.
Conclusion: Be Zhaga-Ready or Be Left Behind
Smart lighting in Europe is no longer an option, it’s a mandate driven by regulation, sustainability, and rising urban expectations.
City planners, OEMs, and EPC contractors must now:
- Invest in future-ready platforms
- Meet certification standards like CE, RoHS, and Zhaga
- Enable plug-and-play lighting control systems that adapt over time
Lead-Top’s Zhaga Book 18-compliant photocells and sockets are purpose-built to meet the demands of modern cities, delivering not only energy efficiency but also true interoperability and remote functionality.
In the smart streetlight revolution, Zhaga Book 18 is the connector to the future. By integrating Zhaga Book 18-compliant controllers, you ensure your LED lighting projects are:
- Future-proof
- Interoperable
- Compliant with EU policy goals.
