Glo Brite® PF100 Exit Signs utilize next generation photoluminescent technology to absorb and store ambient light for dark places. During an emergency blackout or low visibility conditions, this stored glowing energy is immediately visible, creating a clear, recognizable photoluminescent egress indicator. During an emergency blackout or smoky conditions, this stored energy is immediately visible, reducing the risk of panic or injury during an emergency evacuation while also reducing energy and maintenance costs.
