What is emergency lightingEmergency lighting is a critical safety system designed to provide illumination during power failures, fires, natural disasters, or other emergencies that disrupt normal lighting. Unlike standard lighting, which relies on the primary electrical grid, emergency lighting operates independently through backup power sources such as batteries or generators. Its primary purpose is to ensure occupants can safely evacuate buildings by clearly marking exit routes, stairwells, and hazard-prone areas. This system is not merely a convenience but a legal requirement in most jurisdictions, governed by standards like the NFPA Life Safety Code (NFPA 101) and UL 924, which mandate specific performance criteria for placement, duration, and intensity.
