For building and facility owners or managers striving to meet fire and safety codes, new “dual technology” exit signs are combining the efficiency of LED lighting with revolutionary new photoluminescent materials to increase reliability and performance over decades of use.
This hybrid approach combines two established exit sign technologies in a single unit – LED and photoluminescence. During normal power conditions, the sign is illuminated with highly efficient LEDs. When the power goes out, a translucent exit stencil diffusor made of photoluminescent material provides the illumination. This is charged by the LEDs while electric power is provided to the sign.
