This paper presents the design, implementation, and evaluation of a DC-based public lighting system installed in the Buitenhof neighborhood of Delft, Netherlands. The system replaces a conventional AC setup [1] with a bipolar DC grid incorporating solid-state protection and dual-end ring feeding. Key objectives included improving operational efficiency, reducing material costs, and simplifying maintenance. The modular cable architecture and improved fault detection capabilities contributed to faster diagnostics and higher system reliability. Continuous monitoring and remote control of the lighting grid were achieved through solid-state breakers, offering enhanced data visibility and control. Overall, the project demonstrates the viability and advantages of adopting DC technology in urban public lighting infrastructure.
