greater than expected, battery weird

The Ninjago figure is certainly 25 cm tall (is determined in the description) and thus hardly a flashlight but rather a night light for bed (which I bought it as well). The helmet is removable and sits unfortunately quite loose, so that the usually lies somewhere else.

Initially, the light is very bright (not adjustable). If it is longer in use, it is becoming weaker. There is only one on-off switch. If one then turns the lights out and is reused the next night at a time back enough energy there.
