Keep both hands on the job with light right on the spot. Equipped with a magnetic tail cap plus an optical head that rotates 180 degrees, the PS400S flashlight not only features famous POLYSTEEL® strength but combines hands-free positioning with dynamic directional beam-aiming. Whether from the hood of the truck or the side of a pipe, the PS400S holds fast and shines bright—putting you in control of the situation. A heat-welded, ultra-durable polyethylene exterior joins forces with a stainless steel core to withstand the harshest treatment. Featuring our PURE BEAM® optical system, this palm-sized TWIST FOCUS™ light combines two beams in one—with seamless transitions between Ultra View Flood Beam and BULLS-EYE™ Spot Beam. Boasting a run time of up to 27 hours on low, the three-mode PS400S maxes out at 440 lumens bright with a beam distance of 210 meters on high. This flashlight is storm proof, crush proof, drop proof, and dust resistant—to give you confidence no matter how rugged the work gets. 

With Coast’s commitment to quality, the Polysteel 400S Flashlight is impact resistant, stormproof and its LED is virtually unbreakable. The Polysteel 400S Flashlight is backed by Coast’s lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards.
