How long do the emergency lights last on the CRJ 700?

Emergency lighting on the CRJ 700 is powered by an independent emergency power source so it stays on even if the main electrical system fails. The system is designed to provide continuous illumination for 20 minutes, including exit signs and floor-path lighting, to guide passengers to exits during an evacuation. A shorter duration wouldn’t give enough time to evacuate safely, while a longer duration isn’t part of this aircraft’s standard emergency lighting design.
