The BLACKHAWK! Sentinel PL3 XTR utilizes the latest generation 3-watt CREE LED and produces 65 lumens of light on one CR123A- 3-volt lithium battery. The Sentinel PL3 XTR fits in the palm of an officer’s hand but is bright enough to illuminate objects up to 65 meters. The Sentinel PL3-AA XTR boats more light output than any “AA” battery powered light using 3-watt CREE LED and producing 60 lumens of light on two AA batteries. Both Sentinels have a “clickable” tailcap for either momentary or constant on activation.
