The logo can be same as regular debossed, embossed or printed on the glowing wristbands. After exposure to natural light, fluorescent light, and ultraviolet light, the phosphor can store the light energy, stop the light and release it slowly in the way of fluorescence, so the light can still be seen at night or in the dark, lasting for hours to more than ten hours. The luminescent powder can be automatically lit in the dark. The main component is rare earth, which belongs to inorganic materials. The luminous powder first absorbs a variety of light and heat, converted into light energy storage, and then automatically luminescence in the dark, by absorbing all kinds of visible light to realize luminescence. The product does not contain radioactive elements, and can be used indefinitely, especially for short wave visible light, sunlight and ultraviolet light (UV light) under 450 nanometers. Accept the ability. A UV rubber bracelet can transfer it’s color darker under sunshine when absorbing UV light. It transfer to purple or blue normally which indicating the strength of the UV index.
