  • Features
    • Crush Proof

      The Crush Proof feature combines a super-tough stainless steel core with a grip-textured poly-nylon exterior to build unimaginable strength into highly functional lights

    • Drop Proof

      Verified Drop Proof by ANSI FL1 drop testing from 3 meters high for use in rugged, high-impact environments.

    • Dual Power

      Options to stay ready. With COAST Dual Power technology, you have the choice to power your light with USB-rechargeable batteries or with standard alkaline batteries.

    • External Device Charging

      Power any USB-enabled device. Select COAST lights feature a special external charging system that allows other devices to recharge from an easy-to-carry COAST handheld battery pack.

    • High|Medium|Low

      Control your light power with the push of a button. Cycle between full light, medium light and low light options.

    • IPX8 Rating

      Work or play in a downpour—or even underwater. COAST lights that have passed the IPX8-level waterproof test keep working even after 6 hours at a depth of 3 meters (9.9 feet).

    • Pure Beam Focusing Optic

      Pack two powerful beams into one and seamlessly transition—with no halos or hot spots—between short and long-range viewing. COAST’s patented focusing technology adapts to your need. The Ultra View Flood beam delivers edge-to-edge clarity in a broad circle of light up to 11.5 feet / 3.5 meters across, and the Bulls-Eye Spot beam sends a sharp ray of light at a distance of up to 1151 feet / 351 meters, with a transitional halo around the spot to increase the effective viewing area.

    • Twist Focus

      Dial in the shape of light you need for the situation. COAST’s Twist Focus system makes it easy to move between spot and flood beams by simply rotating the head of the flashlight. 

    • USB Insert

      Charge directly from AC, DC, and USB using the USB Insert on the flashlight. The insert is protected under the tail cap of the light. 

    • Waterproof

      Beam bright even in a downpour. COAST waterproof lights and headlamps keep shining—in full luminescent power—even after being submerged underwater for hours.
