Shine bright through the elements. Built waterproof with an ultra-strong, lightweight polymer handle, the GX20 flashlight goes big on brightness and never backs down. This go-anywhere light offers four modes—medium, high, Turbo, and low—with a max output of 1200 lumens. Use the COAST-patented PURE BEAM® optic and TWIST™ focus system to transition seamlessly between the edge-to-edge clarity of the Ultra View Flood Beam and the long-range precision of the BULLS-EYE™ Spot Beam. No storm, splash, or even submersion down to 1 meter (3 feet) will stop you. The grip-textured handle features a lanyard loop, which doubles as an anti-roll tail cap so that you can set the flashlight down and not worry about it getting away on uneven surfaces. Engineered with COAST Dual Power technology, the flashlight runs on four AAA alkaline batteries but can also operate using a COAST ZITHION-X ZX750 rechargeable battery (purchased separately). The GX20 is constructed of top-grade materials to meet IP67 waterproof and dust-resistant standards and is backed by a lifetime warranty. 
  • Features
    • Alkaline Dual Power

      Each COAST Alkaline-Dual Power is compatible with COAST Extreme Performance alkaline batteries and other standard alkaline batteries. Each product can also be powered with a COAST ported ZITHION-X™ rechargeable battery. This offers you the convenience of alkaline and the cost efficiency of rechargeable battery. 

    • 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.

    • Dust Resistant

      Take on any dirty work environment with this dust resistant light.

    • 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, and the BULLS-EYE™ Spot Beam sends a sharp ray of light at a distance with a transitional halo around the spot to increase the effective viewing area.

    • Turbo Mode

      The XP lights not only features standard light modes but also COAST’s signature Turbo Mode for overpowered light in critical situations.

    • 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. 

    • 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.
