Egress photoluminescent tape is a smooth demarcation tape, used for marking areas in buildings to guide you during power outs or lights out situations. The glow in the dark properties are from photoluminescent powder applied to the base film. When the lights go out, the powder, which is full of photons that store energy from natural or artificial light, release this energy in a bright glow, guiding you down stairways, along walkways and through door ways and exits.
Luminance of glow in the dark material is measured in millicandelas per square meter ( mcd/m2 ). Measurements of products are judged on how long an after glow takes to reach 0.32 mcd/m2, which is when it is rendered ineffective. Premium is the best performer, at full charge taking approximately 1800 minutes ( 30 hours ) to reach 0.32 mcd/m2. Super takes approximately 450 minutes ( 7 hours ) to reach that mark. ASTM 2072 stipulates that the levels of luminance at 10 minutes should be 30mcd/m² and at 60 minutes should be 4.4mcd/m² and from the above results we can show that they far exceed these regulation requirements.
