  1. An Emergency Light is a battery-backed lighting device that comes on automatically when a Building or Property experiences a power outage or in the event of fire.
  2. Every model  requires some sort of a battery or generator system that could provide electricity to the lights during a power outage. The earliest models were incandescent light bulbs which could dimly light an area. The modern emergency floodlight provides a high-brightness, wide-coverage light that can illuminate an area quite well. There is now LED emergency lights which are smaller in shape and storage battery but are as bright or even brighter than the normal flood light.
  3. Modern emergency lighting is installed in virtually every commercial and high occupancy residential building. Latest model emergency lights usually have a test button of some sort which temporarily overrides the unit and causes it to switch on the lights and operate from battery power even if the main power is still on. 
    Most emergency lights  will need to last for a minimum of 90 minutes on battery power during a power outage, this is why we need to test and provide maintenance for these lights.
