Emergency Light Definition

Properly placed and functioning emergency lighting fixtures can be the difference between life and death. When AC power to a facility is lost and general lighting systems fail to operate, emergency light fixtures are relied upon to provide emergency egress lighting. Emergency lights must remain on for a minimum 90 minutes after a facility loses power, providing ample time for occupants to safely navigate to the outside safety.

Every type of building and facility in the United States is required to have emergency lights installed throughout the structure. Only buildings featuring backup power generators that provide emergency power to a building’s general lighting system are exempt from this requirement. If your facility does not have a backup generator then it is required to have emergency lighting fixtures installed throughout corridors, stairwells, and rooms.

Emergency Light Operation

All emergency lights require a constant source of electricity, either 120 or 277 volt AC power. Emergency lights also contain small battery packs within them, which are part of the “battery backup system”. Emergency lights only operate when electrical power is lost, making some wonder why emergency lights need AC power at all. The reason behind this is that emergency lights use AC electrical power to charge the battery backup system, insuring that it is constantly ready to operate and provide emergency illumination when AC power fails during an emergency situation.

Types of Emergency Lights

Wet location emergency lights are weatherproof. They can be used indoors and outdoors. Halogen lamps produce brilliant illumination.

There are many different types of emergency lights, each of which has its own distinct features and applications. Finding the right emergency light is important to you and to us. We offer a wide variety of models that are all UL 924 Listed for the United States.

Twenty-four hours is the amount of time required to properly and fully charge the battery backup system of an emergency light. After this time period elapses, the emergency light is prepared to provide a minimum 90-miuntes of emergency illumination. A test button that simply presses in is installed on all emergency lights, allowing easy testing of the battery’s capability. Pressing the test button in cuts off AC power and switches the unit to battery power.
