Philips Emergency tube light are rechargeable, energy efficient emergency lights
An emergency light is a light that is designed to provide illumination that is necessary for safety in the case of a power outage. When the main power supply is disconnected and normal electrical illumination fails, emergency lighting is used to provide illumination in an emergency scenario. A fire or a power outage could cause the loss of mains electricity. Without emergency lighting, occupants may be exposed to unexpected darkness and may be in danger, either physically or psychologically.
