Emergency lights are permanently mounted lights that automatically turn on during a power loss within a building. They draw power from their internal batteries and are designed to provide light for a minimum of 90 minutes. These lights are typically used to light pathways leading to exits from offices, stores, warehouses, and other buildings. They help prevent injuries by allowing people to find their way out of a building. They also supply light for first responders or maintenance personnel working within the building during a power outage.

Emergency lighting and accessories provide light and mark exits to help prevent injuries in emergency situations such as a power failure. Emergency lights turn on when the power goes out to supply a limited amount of light for those within the building. They're typically used along with exit signs to aid building evacuations. Lightsticks are a temporary light source that people can carry with them to find exits, conduct searches, signal for help, and direct traffic. Emergency lighting accessories include battery backup and standby power systems to keep lights on during a power outage.
