Technology — Controls
Ready for smart networks.
A luminaire that simply lights is fully functional — but a luminaire that can be controlled, monitored, and connected to sensors is an infrastructure investment that can evolve with the city's needs, even years after installation.
Four Interfaces
Choose your level of control.
0-10 V
Analogue dimming via a control signal from an external device. Simple and compatible with many existing control systems.
DALI-2
Digital bus protocol with individual addressing, group control, and status feedback per luminaire.
Zhaga Book 18
Standardised mechanical and electrical interface for sensor nodes on the top surface of the luminaire.
Fixed
Constant output without dimming capability. The simplest installation configuration for lower control requirements.
DALI-2
Every luminaire, individually addressable.
DALI-2 (Digital Addressable Lighting Interface) is an internationally standardised bus protocol in which each luminaire receives its own digital address. This makes it possible to control individual luminaires, group them freely by geography or function, and apply individual dimming schedules — all from a central control unit.
Unlike analogue 0-10V control, DALI-2 also provides feedback: status, operating hours, and fault indication can be read back from each luminaire, simplifying preventive maintenance and reducing unnecessary site visits.

Zhaga Book 18
A standardised socket for tomorrow's sensors.
Zhaga Book 18 defines a standardised mechanical and electrical interface on the top surface of the luminaire where third-party modules — occupancy sensors, environmental sensors, cameras, or mobile network gateways — can be mounted without replacing or modifying the luminaire itself.
For a local authority, this means today's lighting investment can evolve into a sensor platform for smart city applications when the need arises — without a new luminaire procurement.
Control Systems
Open interfaces, established partners.
VALDUR's DALI-2 and wireless interfaces make the luminaire compatible with several established control systems and sensor platforms, from simple radar-triggered dimming to fully connected mesh networks. Wireless radio can be built directly into the luminaire thanks to the SMC housing's radio transparency — no external antenna or cable gland required.
Radar Control
Comlight
24 GHz Doppler radar with central control unit. Operates with or without a gateway, in chains of up to 254 luminaires.
Wireless Mesh
LumenRadio AirGlow
Embeddable wireless mesh solution (MiraMesh). Commissioned via mobile app without requiring internet connectivity, with scene and group control.
Bluetooth Mesh
Casambi
Wireless control via Bluetooth Mesh. Commissioning, grouping, and scheduling managed directly from the mobile app.
DALI-2 / Gateway
Tridonic
Standardised DALI-2 systems with gateway. Supports dual PIR sensors for occupancy-triggered dimming.
Central Management
Capelon
Central management systems with gateway for monitoring and controlling entire luminaire fleets from a single interface.
Sensor Nodes
Specific nodes for the Zhaga socket.
A selection of sensors currently available for mounting in the Zhaga Book 18 socket or directly on the column.
Radar Sensor
Eagle Eye / Eagle Eye 3.0
Occupancy detection via radar. Available in a Zhaga-mounted version for the socket on the top surface of the luminaire and in a column-mounted variant.
PIR Sensor
TE Connectivity
Passive infrared motion sensor (PIR) for occupancy-triggered dimming and switching.
PIR Sensor · Bluetooth Mesh
Easyform HIR15/BLE
PIR motion sensor with built-in daylight sensing, DALI-2 dimming, and Zhaga Book 18 compatibility. Commissioned and controlled wirelessly via Bluetooth Mesh in the Koolmesh app.

Frequently Asked Questions
About controls
Can VALDUR be controlled alongside existing DALI installations?
Yes. DALI-2 is an open, industry-standardised protocol and VALDUR can be integrated into existing DALI systems from other suppliers, provided those systems comply with the same standard.
What can be connected to the Zhaga Book 18 socket?
Occupancy sensors, environmental sensors (temperature, air quality), traffic and pedestrian flow counters, cameras, and mobile network gateways from any third-party manufacturer that supports the Zhaga Book 18 standard.
Does the Zhaga node require a separate power supply?
No. The interface provides power to the node directly from the luminaire's own supply, making installation straightforward without additional cabling.
Is it possible to upgrade from 0-10V to DALI-2 after installation?
This depends on the cabling to the luminaire. Please contact POLAB for advice on upgrade paths for your specific installation.
