The Nite Glowring, manufactured by a company who produce “military equipment and other need-to-see-at-night items”, will provide you with a glowing light using tritium – the same kind of radioactive material that was used for this other glowing keychain.

Of course, everyone knows that laser-sealed borosilicate glass vials that are internally coated with phosphor will create a cold energy that produces a light source when injected with gaseous tritium. It’s as plain as the nose on your face.

A Glowring is small enough and tough enough to attach to anything you might need to use in the dark, a bunch of keys being the most obvious. But because they can glow for up to a decade, you can leave them hanging off things that only come out once in a while like fishing gear and camping equipment. It does have to be pretty dark to see the glow, but that’s the point.

The Nite Glowring is available over at the Firebox.com website for £9.95 (about $15 USD). You will have three different colors to choose from: blue, pink and green.

This tiny keychain glows continuously for 10 years using tritium, a radioactive material used in watches, compasses, gun sights and other products you might use in a dark environment.
