The present work seeks to increase the level of illuminance in the district of Santiago de Surco, which is below the minimum required by regulations. The methodology used is Lean Six Sigma, which begins with the “Define” phase, where data collection was carried out in the five selected Surco zones, it was determined that zones 2 and 3, Jr. Combate de Iquique and Jr. Almirante Grau, respectively, are the ones with the lowest lux. In the next phase, "Measure", it was validated that these areas have a lux level lower than the average, which according to regulations should be between 5 and 10 lux, identifying that only 47% of the light poles in these areas comply with the rule. In the "Analyze" phase, the focus was on identifying possible causes that could affect the quality of street lighting. These are the height of the pole, the condition of the lighthouse, and the type of light. Thanks to the development of a mathematical equation, in the improve and control phases, the potential to increase the average illuminance level has been identified, going from an average of 3,107 to 5,370 lux. The projected benefits are estimated at an environmental impact of 1,402.33 TCO2 and an annual economic impact of $34,800.00.
