Imagine you’re in a dark room. The only source of light is coming from the door. You can see the exit, but you’re not sure if you can make it to the door in time. Exit lighting is designed to help people find their way out of the darkness in an emergency. Exit signs are required by law in many commercial buildings and for good reason. In a fire or other emergency, every second counts. Having marked exits can mean the difference between life and death. Exit lighting is also important for security purposes. In short, exit lighting is a critical safety feature that no commercial building should be without.
