The Die-Cast Aluminum LED Exit Sign with Battery Backup from Nora Lighting offers strong service with a straightforward design. The sign is made from die-cast aluminum and keeps a low profile until it is needed. It can go without maintenance for years, holding energy-efficient and powerful LED lamping inside. The compact fixture shines in low-maintenance areas like commercial or industrial locations, where low maintenance requirements and a damp rating keep it working. A built-in battery provides 90 minutes of power in any emergency, blazing out in the darkness to show the way out if the regular power source disconnects.
