The Fulham FHEM12-WW is designed to meet all codes and regulations, and even go above and beyond, being able to supply emergency lighting in wet and damp locations. Although the FHEM12-WW is a waterproof emergency fixture, it is still compact and low profile making it perfect for installation in plain view. The Fulham FHEM12-WW will run for up to a massive 90 minutes during the event of an emergency power outage thanks to the high grade Ni-Cad battery.
