History of Photoluminescent Technology and Safety

Photoluminescent technology - "glow-in-the-dark" in simple terms - was first utilized two decades ago in marine applications, after prominent ship and oil rig disasters demonstrated the hazards of relying on powered systems for egress lighting.

Later the FAA approved the use of photoluminescent material in airplane cabins for aisle pathway marking. More recently, leading cities and states around the country, including New York City and in California, have adopted photoluminescent egress systems as a matter of law.

Today, non-toxic and non-radioactive photoluminescent technology has progressed to the point that Underwriters Laboratories now certifies the use of especially high grades of this material for use in the UL 924 EXIT signs mandated by building codes throughout the United States and Canada.

No electricity used, no energy used, no lamps and consumables to replace. In fact, replacing, just one LED electrical EXIT sign with a Clarion photoluminescent exit sign eliminates 1.2 tons of CO₂ emissions over the exit sign's 35-year life span.

Photoluminescent EXIT signs. Fail-safe. No energy.
