Coast GX20 Flashlight

The COAST GX20 Flashlight is a rugged, high-performance LED flashlight built for demanding work environments, outdoor adventures, and everyday reliability. Delivering up to 1,200 lumens of powerful white light, the GX20 combines durability, versatility, and advanced optics in a compact, easy-to-handle design. Engineered with COAST’s patented PURE BEAM® optic, the GX20 provides bright, edge-to-edge clarity with no dark rings or hot spots. The intuitive TWIST™ Focus System allows you to smoothly shift from a wide Ultra View Flood Beam for area lighting to a focused BULLS-EYE™ Spot Beam for long-distance visibility, making it ideal for worksites, inspections, camping, and emergency use.

Built to handle tough conditions, the GX20 features a lightweight yet impact-resistant polymer body and meets IP67 waterproof and dust-resistant standards. It performs reliably in rain, splashes, and even temporary submersion up to 1 meter (3 feet). A textured grip ensures secure handling, while the anti-roll tail cap with integrated lanyard loop prevents the flashlight from moving on uneven surfaces. Powered by COAST Dual Power technology, the GX20 runs on four AAA alkaline batteries (included) or can be upgraded with a COAST ZITHION-X™ ZX750 rechargeable battery (sold separately). Backed by the COAST lifetime warranty, the GX20 is a dependable lighting solution designed to last.
