Millet night light 2 inexplicably bright there are only two reasons: 1. The quality of the light itself has problems; 2. Something triggered the light.
First check the second item, you put the lamp into a position that will never be triggered, observe whether there is a situation of their own light, if there is no longer their own light that the light itself is no problem, if it is still their own light that the quality of the light itself has a problem, generally the second item is more likely, the possibility of the quality of the light itself is still relatively small
