Emergency lighting systems are an essential safety feature in buildings that provide illumination during a power outage or emergency situation. These systems are designed to ensure that occupants can safely evacuate the building in the event of an emergency. Emergency lighting systems typically consist of backup power sources, such as central battery systems, integral batteries within fittings or generators, and strategically placed light fixtures that provide visibility along emergency egress pathways.

In addition to illuminating pathways, emergency lighting systems often include exit signs that provide clear direction to building occupants. These signs are typically illuminated with bright, easily visible letters, and symbols that are visible even in low-light conditions. Overall, emergency lighting systems are a critical component of building safety, and regular maintenance and testing are necessary to ensure that they are functioning properly.
