Our take on the GX20

The Coast GX20 is a waterproof handheld flashlight with a lightweight polymer body and a maximum output of 1,200 lumens across four modes: low, medium, high and Turbo. Its PURE BEAM optic with the TWIST focus system slides between a wide Ultra View flood beam and a tight BULLS-EYE spot beam, so one light covers close work and distance. It is rated for submersion to 1 meter, and the grip-textured handle has a lanyard loop that doubles as an anti-roll tail cap. It suits homeowners, campers and tradespeople who want a tough general-purpose light rather than a compact everyday-carry torch; rivals in this class often match the output but fewer combine focusable beam, waterproofing and anti-roll design in one polymer body.

About the GX20

The Coast GX20 is a waterproof flashlight with a lightweight, ultra-strong polymer handle. It has four modes: low, medium, high and Turbo. Maximum output is 1,200 lumens.

The PURE BEAM optic and TWIST focus system let you change between two beams. The Ultra View Flood Beam gives edge-to-edge clarity. The BULLS-EYE Spot Beam gives long-range precision.

The handle has a grip texture and a lanyard loop. The loop also works as an anti-roll tail cap, so the flashlight stays put on uneven surfaces. It meets IP67 waterproof and dust-resistant standards and can be submerged to 1 meter (3 feet).

Questions and answers

How bright is the Coast GX20?
It reaches 1,200 lumens on Turbo, with low, medium and high modes below that. Turbo is best for short bursts; lower modes stretch runtime.
Is the GX20 really waterproof?
Coast rates it for submersion to 1 meter (3 feet), so rain, splashes and accidental drops in water are covered.
What is the difference between flood and spot beam?
The TWIST focus slides the lens between an edge-to-edge Ultra View flood for close work and a BULLS-EYE spot for distance. One light covers both.
Does it come with a battery?
The GX20 runs on standard batteries rather than an internal rechargeable pack, so keep spares on hand for Turbo use.
Will it roll off a table?
The lanyard loop doubles as an anti-roll tail cap, so it sits steady when set down on a flat surface.
Who is the GX20 for?
It suits campers, homeowners and tradespeople who want one rugged, focusable light. Shoppers wanting a pocket-sized everyday-carry torch may prefer a smaller model.
Where is the GX20 cheapest?
At Amazon, for $19.99, as of our latest check.
What do buyers say about the GX20?
Rated 4.6 out of 5 from 51 ratings.
Where can I buy the GX20?
