The Klarus XT21X Pro is a 6.5 inch rechargeable tactical flashlight giving 4,400 lumens on turbo, with a tailcap switch and an anti-roll body.
Four thousand four hundred lumens is a considerable output for a handheld, and turbo holds it for 2.5 hours before stepping down. High gives 1,500 lumens for far longer. The anti-roll body matters more than it sounds. A cylindrical light set on a sloping surface ends up on the floor, and a flat section stops that.
A tailcap switch works with the light held in a fist, and both strobe and SOS sit on the same control. It takes either an 18650 or a 21700 cell, so a spare can be carried and swapped rather than waiting for a charge. Explore more handheld flashlights.
