Our Tritium Self Luminous Exit Signs are non-electrical, self-powered exit signs ideal for locations without AC power. They uses tritium gas to provide a glowing "EXIT" illumination, making it reliable during emergencies, as they do not require electrical connections or batteries. Our tritium exit signs meet fire and building code standards and are housed in a durable, vandal-resistant thermoplastic casing with a poly-carbonate face-plate for outdoor use. Installation is easy with top, side, or surface mounting options, with a low-profile. Our Tritium Exit Signs are available in various colors (green, red, and black), require no maintenance and lasts for 10 to 20 years, after which can be recycled. We offer both single-sided and double-sided models.
