glow in the dark film rapidly accumulates the light energy and emits the glow in the dark during emergency or planned turn off of the lights. luminescent sheets can be perfectly charged even by weak sources of light: office illumination, daylight lamp and others. After the lights are turned off a 10 sq. sm. piece of the film becomes noticable from a distance of 100 m.
