The LED Exit Sign with Battery Backup from Nora Lighting offers safety and long, steady service. Made from injection-molded thermoplastic, the round-cornered rectangular construction features clear lettering and chevron-style arrows across its surface. The LED lamping inside the housing offers a long service life with low maintenance, boosted by a battery backup that ensures that even with a total loss of power, the sign will shine for 90 minutes, lighting the way out.
