Power Free / Photoluminescent Exit Signs

Harnessing the incredible scientific process of photoluminescence, power free exit signs function by absorbing light, then utilize that light energy to glow in the dark. A technology somewhat newer than electrically lit signage, photoluminescent exit signs are nonetheless a highly trusted and extremely reliable option for emergency lighting. Here is a few benefits:

  • Remarkable longevity: In contrast to the impressive longevity even of LED lit exit signs (typically 8-10 years), power free exit signs enjoy a standard lifespan of 25 years.
  • Minimal maintenance requirements: Because this type of lighting relies on the absorption of environmental light, it is virtually completely self-sustaining. Very little light is required to power this type of sign, which can subsist on the basic indoor lighting of most commercial, residential, and retail spaces. (Click here for an example of a standard power free sign unit.)
  • Compliance with legal safety standards: Photoluminescent exit signs meet the same federal guidelines for safety as electrical exit signs, and are fully UL listed for compliance throughout the United States and Canada.
