Warm reminder: Principle of luminescence
It will emit bright light after absorbing a few seconds under the light source at night (the effect is better when illuminated by a flashlight), but it will not always emit light, and it will not emit light during the day! If the luminescence becomes weak, it can absorb the light source again (you can keep cycling)
