Our INFORCE TFx is so light you won&';t notice you&';re carrying it, but its 700 lumens pack a punch no nighttime critter or assailant will soon forget. Loaded with capabilities, handsome in appearance, and with a textured polymer body that feels great in your hand, we won&';t be surprised if you make it your new EDC. Press and hold the tactile tailcap button for momentary, click for constant high, once more for constant low, or quickly double tap to access the strobe function. Optionally disable strobe for simpler operation, or rotate the tailcap to lock out of the device when accidental activation would prove a snare. Provides up to 2 hours of high output, or 12 hours of low output with a single pair of lithium batteries.
