Will Tritium Sights Last Forever?
This video explains the science behind tritium sights, clarifying that they do not last forever. Tritium, a radioactive isotope of hydrogen, decays over time, with a half-life of approximately 12 years. This means the brightness of tritium sights decreases linearly, becoming noticeably dimmer around year 7 and roughly half as bright at year 12. Manufacturers may offer tritium replacement services, but the illumination is not perpetual.
