Cities face big headaches with old systems. Before we talk about smart solutions, let’s look at those problems. Traditional streetlights are often inefficient. They are costly and unreliable. Manual controls and old timers waste energy. They also raise maintenance costs and risk public safety.

Does your city still use old timers or manual controls for streetlights? That wastes energy and money. The lighting control process in many cities is still tied to fixed schedules. This causes unnecessary lighting hours—up to 37% excess usage, according to data from the U.S. Department of Energy.

For example, a state in North America that upgraded to photocell street light systems reported a 42% reduction in electricity bills within a year. The reason? Smart photocells respond in real time to ambient light, turning on only when needed.

Manual maintenance adds more weight. Cities spend up to 28% of their lighting budget just on inspecting and managing lights. A typical outage after a storm can take 72 hours to fix without remote access. With Longjoin’s photocell control systems, that detection and correction happen in seconds, not days.

And let’s not ignore safety. Traditional streetlights have a failure rate of about 15% annually due to surge damage. But Longjoin’s photoelectric protection system with IP66 weatherproofing and dual-mode control architecture ensures 99.98% fault-free operation—a massive leap in public safety.
