Highly durable:  Life Expectancy exceeds 12 years in exterior environments and 20 years in interior applications. There is no limit to the number of charge cycles that the paint can undergo. As long as the durable paint is in good condition it will continue to charge and glow as it did when new. 

 

GID Green is the brightest glowing Glow-in-the-dark Paint and is used for safety and decorative applications. It charges in light then glows for 12 hours in the dark. In normal light the paint is a pale green color and then glows a typical lumo green color in the dark. GID Green is often the color of choice due it having a brighter glow than GID Aqua-blue. 

 

Always paint Glow-in-the-dark Paint onto white colored surfaces to get a good glow so if necessary paint the surface white with a good quality acrylic/PVA wall paint first. 

Bear in mind that many outdoor environments are not dark at night due to street lights, exterior house lights and even moon light (when full moon). If the area is not dark then the glow result may not meet your expectations. If you have seen pictures of "glow paint" on plant pots or pathways and the glow looks as bright as a light then the pictures are not of glow paint; they are either edited pictures, are items with battery operated LED lights under the surface or are UV Paints with an Ultra Violet light shining onto them. If our paints could do this then they would have replaced electrical lights in many applications.
