Well Then, How Long Does Trijicon Tritium Actually Last?

Trijicon tritium lamps are guaranteed to last for 12 years from the date of manufacture with a minimum illumination of 0.2 millicandelas per square meter (mcd/m2). 

The tritium gas will continue to be present in the lamp after it has reached the end of its useful illumination life, typically about 15 years. But the light will no longer be visible.


Tritium: Does It Need to be Charged? 

No, the tritium does not need to be charged. Tritium is a radioactive isotope of hydrogen with two neutrons and one proton in its nucleus. 

  • It has a half-life of 12.3 years, which means that it takes that amount of time for half of the tritium atoms to decay. 
  • Over time, the tritium atoms will decay and release energy in the form of beta particles (electrons). And this energy is released without the need for charging the tritium atoms.

Do Trijicon Night Sights Need To Be Charged?

No, Trijicon night sights do not need to be charged. They use luminescent materials that collect and store energy from ambient light. So when it gets dark, the sights will glow. This makes them ideal for low-light conditions. 

The sights also contain tritium, a radioactive element. And this gives them a longer-lasting glow than other types of night sights.

What Night Sights Do Police Use?

Police officers typically use night sights that are illuminated with tritium, a radioactive isotope of hydrogen. These night sights use small vials of tritium that produce phosphorescent light, allowing officers to aim in low-light conditions.

How Long Will Tritium Last?

Tritium is a radioactive isotope of hydrogen with a half-life of 12.3 years. This means that the amount of tritium present will decay to half of its initial amount in 12.3 years.

  • After 24.6 years, the amount of tritium present will be reduced to a quarter of its initial amount. 
  • After 37 years, the amount of tritium present will be reduced to an eighth of its initial amount, and so on.

This means the amount of tritium present will continue to decrease exponentially over time until it is completely gone.

What Sight Does The Navy SEALs Use?

Navy SEALs use a variety of night vision and thermal imaging devices to observe and target targets in low-light environments. The most common type of night vision device used by Navy SEALs is the image intensifier, which amplifies existing light to provide a visible image of the surrounding area. 

  • Thermal imaging, sometimes referred to as infrared imaging, allows Navy SEALs to detect heat sources to identify potential targets.
