Glow in the dark effect can generally last for a maximum of 4 hours.
The length of glow relies on many factors ie.
1. How bright the light source where the clock is positioned.
2. Even there is light in the room, location of the clock can affect light absorbance which in turn affects the brightness and length of glow.
3. Within the length of glow, brightness is expected to fade gradually. After approximately 1.5 - 2 years, the luminosity of the dial will decrease in strength
