These glow in the dark 5" x 5.25" phosphorescent "NO EXIT" signs on adhesive vinyl are energized by ambient light and will illuminate the instant lights go out. These glow in the dark no exit signs will keep people from trying to exit the wrong way in the event of a power loss or fire emergency. The phosphorescent material is charged by common light sources such as daylight, tungsten filament and fluorescent lights. When exposed to ambient light source, the sign will charge the phosphorescent material to glow for up to 8 hours.
