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. That’s the process of making tritium glow ring.


The manufacturers of the Nite Glowrings, also produce military equipment and other need-to-see-at-night items, have taken this everyday nugget of basic science and made tritium glow ring their business.

A tritium glow ring is small enough and tough enough to attach to anything you might need to use in the dark, especially when you are searching for keys when arrive home late in the night.

Due to its capability to glow for up to a decade, you could just leave the tritium glow ring hanging off things that only come out once in a while like fishing gear and camping equipment.

However, it has to be pretty dark to see the tritium glow ring to shine. You could get the tritium glow ring here.
