Implement Urban Public Lighting Efficiency Improvement

The article is part of a series of articles on how local governments and utilities work together to improve energy efficiency. It describes a partnership strategy for implementing urban public lighting(Classic) efficiency improvements, which is the most common type of public lighting.

In the past decade, public lighting technology has been greatly improved, enabling high performance and high efficiency to be used on a large scale. Efficient technologies such as LEDs, sensors, monitoring systems and controls are beginning to be widely used in public lighting systems. While these technologies typically have high upfront costs, they can reduce energy and maintenance costs over time and offer many additional benefits. LEDs are the most effective public lighting technology, and their cost is quickly reduced, but the cost per luminaire is typically 2-4 times higher than traditional high-pressure sodium technology. However, it uses 30-50%+ less energy and significantly reduces energy costs over its lifetime. In addition, because LED lamps have a longer life than traditional technologies (usually 7 to 10 years to replace, not 2-3 years), they can significantly reduce the cost and personnel time associated with replacement and maintenance.
