The range starts from the lowest grade, to the highest grade, which can glow for more than 30 hours. There are no higher grades than this in the world. This glow in the dark powder pigment works by absorbing and releasing light energy in a continuous cycle. When the surrounding is bright, it absorbs light energy and the glow in the dark Powder pigment can be re-charged many times over just by exposing it to any light source, preferably those with Ultra Violet rays like sunlight or UV light (black lights).
