With more than eight hours of illumination time requiring no electricity or battery, signs made with this material have become the benchmark for safety and regulatory sign requirements. These materials are used extensively in the cruise ship industry, as well as passenger trains and in much of new high-rise construction. The luminescence of the material we use surpasses all regulation requirements for use in fire evacuation and safety. Examples of applications: fire evacuation, floor markings, stair treads, emergency exits, stairwell wayfinding and vinyl lettering.
