It is powered by the new SL-B50® battery pack that charges inside or outside of the light using a USB-C cord. It features TEN-TAP programming which gives the user the choice of three selectable programs: high for 2000 lumens, a 262m beam, and 2.5 hour run time, Medium for 570 lumens, 142m beam, and 4.5 hour run time, and low for 100 lumens, 60m beam, and 25 hour run time. It also has a strobe feature for signaling or disorienting with a 4 hour and 25 minute run time. The Protac 2.0 Flashlight is IP67 rated, dust tight and waterproof to 1 meter for 30 minutes, and 2 meter impact resistance tested. It is constructed of 6000 series machine aircraft aluminum with Type II MIL-Spec anodized finish. The anti-roll head prevents the light from rolling away when placed on a flat surface. It includes USB-C cord, removable pocket clip, nylon holster, and lifetime manufacturer warranty.
