Our take on the Coast GX20 LED 1200 Lumens Flashlight

The Coast GX20 is a 1200-lumen handheld flashlight with four modes (low, medium, high, Turbo) and Coast's PURE BEAM optic with TWIST focus, which slides between a wide flood beam and a tight spot. It runs on four AAA alkalines or an optional ZITHION-X ZX750 rechargeable pack sold separately, and it is rated IP67 for dust and water, including submersion to 1 meter. The polymer body keeps it light, and a lanyard loop doubles as an anti-roll tail cap. At $19.99 at Amazon as of November 5, 2026, it sits at the low end of its recent price range, with two stores listing it new.

About the Coast GX20 LED 1200 Lumens Flashlight

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.

Questions and answers

Is the Coast GX20 worth it?
At $19.99 at Amazon as of November 5, 2026, it is a good value if you want high brightness and a focus beam without spending much. The catch is that you pay for AAA batteries over time unless you buy the ZX750 rechargeable pack.
Does the GX20 come with a rechargeable battery?
No. It ships to run on four AAA alkaline batteries. The Coast ZITHION-X ZX750 rechargeable battery is sold separately and swaps in without other changes.
How bright is the Coast GX20 and how long does it run?
Turbo tops out at 1200 lumens, with low, medium and high below it. Expect the shortest runtime on Turbo and the longest on low; AAA alkalines drain fastest at the top end.
Is the GX20 waterproof?
Yes. It is rated IP67 for dust and water and can be submerged to 1 meter (3 feet). That covers rain, splashes and accidental drops in water.
What is the difference between the flood and spot beam?
The TWIST focus ring moves between an Ultra View Flood Beam for wide, even light up close and a BULLS-EYE Spot Beam for reaching distance. Twist the head to switch between them.
When is the GX20 cheapest?
It has been listed near $20 at Amazon as of November 5, 2026, which is at the low end of its recent range. Flashlight prices often dip around Black Friday and holiday sales, so watch for drops then.
