    15+ years is the standard answer retailers will tell you... but they seem to start dimming sooner than that.

    They should be expected to last 10-12 years. After that, one could expect them to be approximately half as bright as when new.

    I think the 10-12 is what most say, and from the night sight factory it is 15, but you don't know when they actually were created.

    The Half Life of Tritium is 12.5 years meaning that in 12.5 years your sights should be half as bright as when the tubes were filled.

    I don't think they would be very useful in 25 years though. Not even for a full 12.

    I guess it depends on how old the Tritium is when they make the gas tubes and how long they sit "in stock" before they are sold and installed.
    I really don't think you get even close to 12.5 usable years out of them.

    The first imported Tritium sights were on my Galil and they were decent for about 6 years.
    Realistically...I planned on 5 useful years on my Glock sights and that has proved to be pretty close to accurate unless your eyes are better than mine.
    Mine could stand being out for new ones right now.
    They still glow and ARE still "night visible" but, not like when they were spanky new - that's for sure.
