Pick mid-size, pack big power. Designed as an all-around flashlight that travels as well in a gear pack as it does in a tractor, the PS400 flashlight comes in at just under 6 inches long and 7 ounces but packs all the strength our POLYSTEEL® lights are known for. 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 26 hours on low, the three-mode (high, medium, low) PS400 maxes out at 440 lumens 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 400 Flashlight is impact resistant, stormproof and its LED is virtually unbreakable. The Polysteel 400 Flashlight is backed by Coast’s lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards.
