General lighting and public lighting in particular are accounting for a large proportion of power consumption, including street lighting system. Modernizing the street lighting system to save energy and reduce operating costs, while ensuring the quality of lighting is considered an urgent solution today. This article is the result of the research to create energy-saving control cabinet for the street lighting system. The result of the research show that, by reducing and stabling voltage at the off-peak time, the power consumption of the bulbs is reduced. This stabilization also avoids overvoltage when the voltage is high at night which enhances the life of the bulbs.
