Efficient, remotely managed street lighting.

S4 takes part in public street lighting and large-site lighting projects: lighting design by road type, efficient LED luminaires and remote management to control, configure and monitor lighting from a single platform.

Who it is for

Lighting manager at a public entity

Failures detected without patrols and consumption matched to traffic.

Industrial park or residential complex administrator

Internal roads well lit and easy to maintain.

Large-site manager

Campuses, shopping centers and sports venues with centralized control.

Know which luminaire has failed without going out to look for it.

With conventional lighting, failures are found through complaints or night patrols, dimming is not possible and consumption is the same all night even when traffic drops.

You need it if you recognize any of these signs:

  • Failures are detected through complaints or patrols.
  • All luminaires run at 100% all night.
  • There is no geo-referenced inventory of light points.
  • A switch to LED is planned and remote management is wanted along with it.

How the system is built.

We recommend luminaires with a standardized socket (7-pin NEMA or Zhaga) so the remote-management controller can be replaced without replacing the luminaire, and platforms with open interfaces.

What is included and what is not.

Included in the service

  • Survey of existing lighting
  • Lighting design by road type
  • Luminaire selection by performance and maintenance
  • Supply and installation of luminaires and controllers
  • Remote management platform and inventory
  • Measurements, testing and training

Out of scope

  • Contract or concession management of the lighting service
  • Medium-voltage electrical networks
  • Poles and civil works, unless expressly agreed

Anything out of scope is coordinated with the right party or quoted separately, and is always stated in writing before we start.

How we do it, step by step.

  1. Assessment

    Inventory of light points, road types and network condition, and review of current consumption.

    DeliverableInventory and assessment

  2. Design

    Lighting calculation by road according to regulations, luminaire selection and remote management architecture.

    DeliverableCalculation report and phased plan

  3. Integration

    Luminaire replacement, controller installation and registration of each point on the platform.

    DeliverableLuminaires installed and geo-referenced

  4. Commissioning

    Road measurements and testing of dimming profiles and alarms.

    DeliverableMeasurement and test report

  5. Operation and improvement

    Fault monitoring, maintenance and profile adjustment.

    DeliverableStatus and consumption reports

Work sequence: each step closes with a written deliverable.

Reference regulations and standards.

These are the usual references for this type of system. The technical report of each project identifies which ones apply, depending on the use, size and location of the installation.

Regulatory reference, indicative

RETILAP
Colombian street lighting requirements: lighting classes by road type, levels and uniformity.
ANSI C136.41 and Zhaga
Socket standards for outdoor luminaire controllers.
RETIE
Colombian technical regulation for electrical installations: governs the service connections and circuits that power the equipment.

What stays in your hands.

  1. Georeferenced inventory

    Each light point with its status.

  2. Calculation report

    Levels by road and luminaire selection.

  3. Measurement report

    Values measured on the road.

  4. Platform access

    Profiles, alarms and consumption.

What people ask us most.

Do you take on public projects?

Yes. Contact us with the project data so we can assess it.

What is remote management?

Remote control of luminaires from a platform: dimming, scheduling, detecting faults and measuring the consumption of each point.

Which regulations apply?

In Colombia, RETILAP sets the lighting classes and levels by road type, and RETIE sets the conditions of the electrical installation.

Can existing lighting be remotely managed?

If the luminaire has a standardized socket, it is enough to install the controller. If not, adapting or replacing it is evaluated; the assessment decides.

Does it work for private roads and campuses?

Yes. Industrial parks, residential complexes, campuses and shopping centers follow the same principles.
