So, what is emergency lighting?
Put simply, emergency lighting is a form of lighting that normally comes on automatically when the power supply to the normal lighting fails.
Emergency lighting is a general term and is divided into emergency escape lighting and standby lighting.
Emergency escape lighting– that part of an emergency lighting system that provides illumination for the safety of people leaving a location or attempting to terminate a potentially dangerous process beforehand. It is part of the fire safety provision of a building and a requirement of The Regulatory Reform (Fire Safety) Order 2005.
Standby lighting– that part of an emergency lighting system provided to enable normal activities to continue substantially unchanged. Standby lighting is not subject to legislation and is generally used within hospital etc when normal light levels are required to operate the building.
