Emergency lighting is important both for your business and home, for landlords it is required that you provide the proper fire safety and emergency lighting for your residence. In one story and two story houses conventional lighting is needed, whereas with four floors, you require emergency escape lighting if the escape route is complex and there is no effective borrowed light.

Emergency lighting should be tested regularly unless they are self testing. Emergency lights with internal backup batteries display a small green LED that indicates that the internal battery is being charged. Older models may have a red light. However, you still have to check the function of the emergency light regularly, as the LED only confirms that the unit charges rather than that the battery will last the full period required or that the bulb is in working order.
