In the event of emergencies where power is lost, building codes require emergency lighting. When everything goes dark, this avenue of escape shines brightly. The Fulham FireHorse FHEX21-WR-EM emergency exit sign 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. In the event of an emergency, a sealed lead-acid battery powers the internal LED for up to 90 minutes.
