The Sentinel™ PL1 produces an impressive 35 lumens in an unbelievably compact size. The entire light is small enough to fit into the palm of your hand but bright enough to illuminate objects or persons at a distance up to 40 meters. At less than 2 oz., you can even mount this versatile lighting tool on the bill of your ball cap via its Pocket Clip design to illuminate diminished light work areas for up to 3 hours.
