Energy LighT





Device placed on the lamp body, communicates directly with the LED driver; allows a direct control of the streetlight on which it is installed, being able to regulate the light intensity in real-time. These devices come with GPS and therefore are geolocated on a map and can be easily applied via prefabricates holes (Zhaga protocol) or they can be installed inside the pole (no need of holes).


Control cabin for the coordination of a certain number of devices. The Gateway is the device that acts as a link between the central unit and the controller installed on the lamps body. It is an element for the collection of all the information that is exchanged between the different devices and is appointed to the communication of these to the cloud. Moreover, it deals with assigning to each driver tasks based on the orders received from the “brain” of the system.



Easy and intuitive graphic interface for the network management.
monitoring of a consumption lamp; allow sending instructions; collecting information concerning installed sensors; receiving warnings about any faults.




The Street Light Controller is compact and can be integrated with ease into virtually all LED street lights. It comes as standard with wireless communication, eliminating the time-consuming routing of data cables and thereby saving installation costs. The Controller can be used with all major electronic control equipment and helps you to reduce energy consumption and keep maintenance costs down to the absolute minimum. In combination with the motion sensor only particular stretches of road being used by people or vehicles will be illuminated.

Through Controller street lamps can be dimmed automatically, when little or no light is needed. As soon as the sensors detect pedestrians, bikes or cars, the intensity of the illumination will be adjusted for that particular stretch of road.

Zhaga Controller features

Impact points over time:
• Optional extensions such as motion sensors, radar, brightness sensors, LED temperature sensors and other options are available
• Dim by timer, light levels, site-mode or automatic-mode
• Individual adjustment of the illumination through continuous dimming
• Real-time profiles with time and weekday dependent dim levels
• Combines the benefits of both the central and independent controlled lights
• 2.4 Ghz radio network with self organized meshing
• 0-10V, PWM- and DALI-output interface combined in one controller
• Can be operated by either 100-240V AC or 12-60V DC
• Low power consumption in operation (0.2 – 0.6W)
• Active monitoring of the light source (LED) temperature
• Switch functionality enables a manual, quick and profile independent illumination for special events or emergency situations
• GPS-Options, to synchronize the time and automatically determine the light position


The esave slControl Gateway (slGateway) extends the existing esave slControl product family and brings your luminaires into the cloud.

New and existing esave slControl systems can be expanded with gateway modules.

The gateway module is a small device, which is attached near the systems and connects to the esave slControl mobile radio network. In addition, the module connects to the esave slControl server through mobile radio or Ethernet. To protect the data against unauthorized access, all transmission paths are encrypted and secured.

The esave slControl server collects the data of all connected gateway modules and makes them available in a user-friendly web application. The connected systems can thus be easily monitored, controlled and manage by any computer with an Internet access.



ELT complies with the Zhaga Consortium smart street lighting specifications ensuring universal compatibility with all LED luminaires with a standardized Zhaga socket .


Streetlight controllers can be installed with ease and quickly.


The data coming Realtime from any luminaires allow to deploy a predictive maintenance plan and always be aware of the lamps’ life status, resulting in less maintenance costs.


The integration with photosensor allows the streetlights to automatically adjust their brightness based on the outside light level


When connected to a motion sensors, the system activates as soon as any presence is detected, optimizing at the best the energy deployment using energy only when and where is needed.
