The LED Exit and Emergency Sign with Adjustable Heads from Nora Lighting keeps you safe when it counts. A rectangular sign with adjustable lamping placed on each side, its durable plastic housing can be installed on a ceiling or wall as needed. The housing resists rust, dampness, and flames with ease, and the sign lights up brightly to indicate the nearest point of egress with signature clarity. The twin LEDs cast a glare-free glow even when the power goes out, thanks to an included battery that can light up its surroundings for up to 90 minutes.
