Xt Df Flashlight

The XT DF has a maximum brightness (primary setting) of 600 lumens when used with the included 18650 rechargeable battery. Dual Fuel (DF) technology allows substitution of two CR123A primary cells (sold separately), boosting max brightness to 635 lumens. The secondary light level is user-programmable at 15, 60, or 150 lumens, or strobe. In keeping with our emphasis on intuitive design and simplicity in our law enforcement tools and training, activation is via a single pressure switch on the tail cap press once to activate the primary/max setting, twice (Double Tap) to activate the user-programmed secondary mode. Setting the secondary light level takes just seconds?simply twist the bezel open to activate programming mode, tap through the levels until you reach your chosen setting, and twist the bezel closed to lock it in. A 3-position twist selector on the tail cap allows choice of intermittent, constant-on or locked.
