What type of lighting provides the minimum light levels needed to assist people when exiting a building?

Egress lighting is specifically designed to ensure safe and efficient movement of people out of a building in emergency situations. It provides the minimum light levels necessary for individuals to find and follow exit paths clearly. This type of lighting is crucial in guiding occupants to safety, especially during power outages or in low-visibility conditions.

It contrasts with other types of lighting. Emergency lighting primarily serves to illuminate areas that may otherwise be dark during power failures but may not always be focused on exit routes. Task lighting, on the other hand, is meant for specific activities or tasks, such as reading or working, rather than for navigating exits. General lighting provides overall illumination for spaces but lacks the specific purpose of directing occupants to safety during an evacuation. Therefore, egress lighting is tailored to the unique demands of safety and accessibility in emergency situations.
