What is Photoluminescence?
Photoluminescent materials (commonly called “glow-in-the-dark”) can absorb and store direct light energy (sunlight, fluorescent, incandescent, etc.) and upon removal of the light source, the stored light is gradually released – the strongest glow is produced during the first 30 minutes of darkness, the most critical period following a power failure or other emergency. The glow can last from a few hours to several days depending on the quality and color. It then fades over a period until reintroduced to a direct light source, so it may start the process again. The pigment can repeatedly absorb energy and emit visible light for over 20 years without any perceivable change of its properties.
Is it environmentally friendly?
Photo luminescent materials are non-toxic, non-radioactive and contain no phosphorus, lead, or any other hazardous chemicals.
More information about the pigment and the colours I use.
Can they be used instead of a reflector?
Although they have a bright glow, it may not be visible from far away in traffic. Stay safe at night, always wear a reflector.
