These LED lighting fixtures are shared by the main lighting and by the emergency lighting. Cost savings are derived from the number of lighting fixtures and consequently from the general maintenance of the system. Using LED lighting fixtures deployed with LED’s results in substantial savings in power consumption. Further, the switching of the main lighting to the emergency mode occurs automatically but it can also be controlled manually.
