Self-Luminous Lighting Explained

The secret to our non-electrical self-luminous sign is the gaseous tritium light sources (GTLS) that illuminate the sign’s letters or pictogram.  A GTLS is a small glass tube internally coated with phosphor and filled with tritium gas.  Tritium gas (H3) is a radioactive isotope of hydrogen that emits low energy radiation in the form of beta rays or electrons.  These electrons energize the phosphor coating thereby causing the GTLS to continuously emit light.  The process of producing light is exactly the same as an electrical fluorescent lamp with the only difference being that the electrons that illuminate a GTLS are supplied by the tritium rather than by an electric current.  They require no external energy source, battery, or activating light source (like a photoluminescent sign) and are therefore the most energy efficient light source available today.

The tritium gas used in our GTLS is a waste or by-product of nuclear energy production.  You may not know it, but here in Ontario, where we’re located, more than 50% of our electricity comes from nuclear energy.  By finding a commercial use for this product we have effectively turned waste into a valuable life safety product.

Our signs have successfully passed the most rigorous ANSI N-540 tests for structural integrity before being approved and licensed by the Canadian Nuclear Safety Commission and the US Nuclear Regulatory Commission. In addition, they meet or exceed the standards of all appropriate regulatory bodies including the National Building Code, Provincial Building Codes, Underwriters Laboratories 924 Standard for Emergency Lighting, and The National Fire Protection Association’s Life Safety Code 101.

At the end of the sign’s effective life it can be returned to us for recycling of all its’ component parts.
