Nitecore SENS AA-2 Flashlight XP-G R5 LED (170 Lumens)

The SENS AA2 has three output levels and the innovative ADT mode (Active Dimming Technology). Aluminum construction with tail cap switch and TIR lens. Uses two widely available AA batteries.

The SENS Series flashlights from Nitecore feature a unique brightness control method that utilizes an acceleration sensor to determine the output mode desired. When the flashlight is turned on from off it will enter high output level when the head is parallel to the floor, medium output level when the head is at 45 degrees, and low output level when the head is pointing straight down. So, the mode is based on the angle of the flashlight when turned on and it stays in that mode unless turned off and on at a different angle (see illustration above).

The Nitecore SENS lights also feature the Active Dimming Technology (ADT) mode, which continuously detects the angle of the flashlight in relation to the floor, while the micro processor uses this data to vary the light output. This mode is activated by turning on the flashlight while the head points straight up. One of the many advantages of ADT mode is significantly longer runtimes when compared to a regular flashlight.
