What Is the Difference Between Maintained and Non-Maintained Emergency Lights?

Emergency lighting is essential for safety in the event of a power failure. The key difference between maintained and non-maintained emergency lights lies in their operation:

Maintained Emergency Lights: These lights are designed to remain on at all times, much like regular lighting. They are commonly used in places like cinemas, theatres, and public venues where illumination is required even during normal operation. In the event of a power failure, they continue to function using their backup battery.

Non-Maintained Emergency Lights: These only turn on when there is a mains power failure. They are ideal for workplaces, offices, and industrial settings where normal lighting is sufficient, and emergency lights are only needed during an outage. Both types typically have a minimum 3-hour battery backup, ensuring adequate illumination for safe evacuation during emergencies.
