NiteCore SENS AA CREE XP-G R5 LED Flashlight The NiteCore SENS AA light is a quality micro light which offers a serious punch - 120 lumens - in a small package. The coolest feature of the light is the Active Dimming Technology - when you turn on the light while pointing it up, it defaults to ADT mode, where, as the angle of the beam to the ground decreases, the light slowly dims.
