Problem Addressed

The Municipality of Tijuana was in an emergency situation.

Since 2012, it faced a serious problem in the operation of its public lighting system, including constant failures, reduced light output, complaints from citizens, and insufficient financial, material and human resources. All this prevented the provision of a good level of basic service to citizens.

During 2015 illumination values were obtained from 47 major roads, only 1 complied the national standard with the required minimum average illuminance, and none complied with the uniformity ratio.

It became necessary to look for an alternative that would allow luminaires to function properly, address citizen complaints, reduce energy consumption and reduce the cost of maintenance.

Major roads were selected to upgrade 6,800 luminaries with LED, which presented greater advantages and benefits like low energy consumption, long expected life, low cost of maintenance and reduction of greenhouse gas emissions.

Solutions Used

In order to define the characteristics of the luminaires that were acquired, the geometric conditions of the road, the luminous efficiency, the voltages and the type of ignition of the luminaires were taken into account.

Thus the suggested power range was determined from the geometric conditions of each road, providing the basis for lighting simulations, made with specialized lighting software. With those simulations, the minimum delivered lumens and luminous efficacy were obtained, with the intention that not only the NOM-013-ENER-2013 (national standard) requirements be met, but that they were exceeded.

Road safety was improved significantly in 68 locations, among them: major city roads, bridges or junctions and the central business district.

Average illumination levels at those locations went from 2.9 lux to 18.5 lux, achieving and exceeding compliance to the national standard.



6,800 luminaires upgraded to LED technology


538% increase to average illumination levels (2.9 lux to 18.5 lux), achieving and exceeding compliance to the national standard


587,000 vehicles use the roads daily


25% reduction of traffic accidents

Something Unique

Establishing minimum specifications of over 115 lm/W (high luminous efficacy) for LED luminaires allowed us to have a winning bid, offering roadway lighting luminaires of up to 130 lm/W, which translates to maximum illumination and decreased energy consumption

Who Should Consider

Any local, state or federal government that has not yet upgraded its old HID or HSP luminaries, which have a high cost of operation and maintenance, and poor illumination levels.
