Lighting is essential for everyday living and particularly critical for public safety. Street lighting provides an opportunity to create an inviting and safe pedestrian environment that encourages people to be active after dark. It is important to select lighting that complements the surrounding environment and provides energy cost savings. To this end, LED lighting has become increasingly popular for its energy savings, long life expectancy, improved color rendering and controllability, and because it is a familiar technology and often considered aesthetically pleasing for cityscapes. LED lighting offers many benefits, including energy savings and long life expectancy. On average, LED lighting consumes up to 80% less electricity than conventional lighting and lasts over five times longer. This in turn reduces maintenance costs since fewer light replacements are needed, while providing better visibility and safety. LED lighting can also be manufactured and customized to produce varying color temperatures which can significantly contribute to the pleasantness of a persons environment. Additionally, LED technology can be used for a variety of other applications, such as art lighting, as well as in the home. Recently, smart lighting systems have become popular, which are gradually replacing the traditional flood and spotlights of past generations. These systems use built-in sensors and wireless controls to create a more customized and efficient lighting experience for homeowners and businesses alike. In summary, LED lighting is an increasingly attractive option for lighting needs in our modern world. It is energy-efficient, long-lasting, controllable, and highly versatile in its applications. With the aid of new smart system technology, LED lighting is likely to become even more popular in years to come.
