Sustained emergency lighting is a type of emergency lighting system that is designed to remain operational for an extended period during a power outage or emergency situation. It typically includes battery backup or generator power to keep the lights illuminated, providing visibility to help occupants safely evacuate the building.
Emergency lights should be installed at regular intervals to ensure adequate coverage and visibility in case of power outage. The recommended distance between emergency lights is typically around 25 to 30 feet apart to provide consistent illumination throughout the space. However, it is important to consult local building codes and regulations to determine the specific requirements for emergency lighting spacing in your area.
A central battery system is a setup where all the emergency lights in a building are powered from a central source, usually a bank of batteries. This design allows for easier maintenance and testing of emergency lighting systems.

An emergency ballast is a lighting ballast that has an internal battery. This battery will store enough energy to power the light for a short amount of time. Typically this battery is not designed to last through long power outages. Rather, it is normally used in conjunction with a backup generator. In the event of a power loss, the ballast immediately carries the load of the light, until the generator comes online. Some manufacturer's do not combine the ballast and the battery in the same metal can; they use 2 separate cans. The battery part in many instances does not light all the lamps of the fixture and it may only light the lamps about half brightness. The purpose is only to assist in evacuating the building
