How long do the emergency lights last on the CRJ 200?

The emergency lights on the CRJ 200 are designed to provide illumination in the event of a power failure or emergency situation. They are powered by a dedicated battery system that activates automatically when normal power is lost. These emergency lights are engineered to last for 15 minutes, allowing sufficient time for passengers and crew to evacuate the aircraft safely or to address an emergency situation. This duration is strategic, ensuring that emergency illumination is available to guide individuals to exits or assist with other critical actions during a brief yet potentially chaotic period following a loss of power. The design and duration are in accordance with safety regulations, providing a balance between functionality and the need for efficient use of battery power.
