Emergency lighting must automatically illuminate exit routes, stairways, and other key areas when normal power is lost to ensure safe and orderly evacuation. According to NFPA 101 Life Safety Code and most local regulations, emergency lights must provide at least 1 foot-candle of illumination along exit paths and remain operational for a minimum of 90 minutes on battery or backup power. Proper installation and regular testing are essential for code compliance and occupant safety.
