What is the real purpose behind lighted LED exit signs?

Power outages occur in businesses, educational and medical facilities across the country every day. Are you prepared for such an emergency? Many people think that the sole purpose of an exit sign is to mark stairwells and building exits. However, that is only a secondary purpose for lighted LED exit signs.

Many times a power outage can be the result of a fire in the building. In such cases, finding the emergency exits can be complicated not only by a loss of power but from the presence of smoke in emergency egress routes. Under these circumstances, lighted exits signs powered by rechargeable backup batteries can literally save lives by allowing individuals to safely exit the building.


Most relevant codes (fire, building, health or safety) require exit signs to be permanently lit. The use of light-emitting diode (LED) technology provides brighter illumination than incandescent lamps, resulting in better visibility in a fire situation. LED exit signs also consume much less energy than traditional incandescent models, typically requiring about 4 watts of power to operate. This results in significant cost savings over the life span of the fixture, especially considering that LEDs have a very long life and may last for 10 or more years of continuous use.
