Self-contained emergency lighting systems operate by being connected to the normal mains power during regular operation. However, in the event of a power outage or emergency, these luminaires seamlessly switch over to an internal battery power source, ensuring continued illumination of exit routes and critical areas. The battery backup power allows the emergency lighting to continue operating for a specified duration, typically for the duration of the emergency or until mains power is restored. This ensures that exit routes remain illuminated and occupants can safely evacuate the building. Self-contained emergency lighting systems offer several advantages, including ease of installation, flexibility in placement, and reliability in providing illumination during emergencies. They are commonly used in various indoor and outdoor applications, including commercial buildings, industrial facilities, schools, and healthcare facilities, to ensure compliance with safety regulations and provide peace of mind for building occupants.
