What Is Tritium and What Does it Do?
Tritium is also known as hydrogen-3 and is a radioactive variant of hydrogen. One of its by-products is a substance that glows in the dark when combined with phosphorous in a sealed space.
The result of this glow-in-the-dark combination is a light source that lasts as long as 25 years. You’ll find it in tactical and outdoor watches because you can check the time and other data without draining battery life. In fact, tritium tubes in watches never need to be recharged!
