The SX300R was created to provide both an excellent focusing beam flashlight and a brilliant, ready-to-go area light. By sliding the body of the light apart, users can easily access the C.O.B. light. The area light features a bright white LED light, solid red, and flashing red light modes. The light’s Flex Charge Dual Power recharging system means it can be powered by either alkaline or lithium-ion batteries. The SX300R includes a magnetic tail cap that allows users to place the light on magnetic surfaces and maximize the full light output of the area light. Harnessing the Pure Beam Optic with the ability to twist focus, the SX300R Flashlight is the ultimate tool for daily use in a variety of distances.

With Coast’s commitment to quality, the SX300R Flashlight is impact resistant, weather-resistant and its LED is virtually unbreakable. The SX300R Flashlight is backed by Coast’s lifetime warranty against defects in materials and workmanship. Tested and rated to ANSI/FL1 standards.

Make the most of your purchase with these add-on products.

S50 Sheath

Regular price $9.00
  • Features
    • C.O.B. Optic

      Get brilliant light tailored for specialized formats and use cases. COAST lights featuring Chip on Board (C.O.B.) technology cast a wide beam handy for up-close work—from a strip of LEDs built right onto the chassis, without a standard optic. 

    • 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.

    • Dual-Color White & Red Beam

      The right light for the moment. The Dual-Color White & Red Beam combines an all-white Utility Beam for general use with a red, anti-glare beam that prevents “night blinding” while also offering a tool for emergency signaling. 

    • Flex Charge

      Power up on your terms. Lights with COAST Flex Charge technology feature a rechargeable battery that can be recharged either inside or outside the light. A simple USB connection to either AC or DC ensures you can always get juice.

    • High|Medium|Low

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

    • Magnetic Tail Cap

      Attach the light to magnetic surfaces. COAST lights with a Magnetized Tail Cap have an integrated magnet that enable you to affix the light to magnetic surfaces for easy storage or hands-free use.

    • 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.

    • 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.
