Detailed Explanation

Photoluminescent materials absorb energy from ambient light (natural or artificial) and release it as visible glow when surrounding light levels drop. For signage, photoluminescent materials provide egress guidance during power outages without requiring electrical connection. Quality photoluminescent signs glow for 90+ minutes, meeting IBC and fire code requirements. Some jurisdictions, including Los Angeles for high-rise buildings, specifically require photoluminescent exit signs and egress path markings.
