In the event of emergencies where power is lost, building codes require emergency lighting. When everything goes dark, these twin beacons of hope shine brightly. The Fulham FireHorse FHEM10-W emergency light is damp location rated and features a universal J-box mounting system for simple installation. Its compact, low profile design makes it ideal for installation in plain view. This FireHorse emergency light includes a push-to-test switch for manual testing of the emergency system. The two fully adjustable LED lamps are powered for up to 90 minutes off of a Ni-Cad battery.
