    Question regarding tritium painted markers on the dial?

    I have a question regarding the tritium painted markers on the dial

    so they don't require "charging" at all (like tritium tubes)?

    or they also need to be "charged"

    i am talking about the tritium paints (like older Fortis, etc), not the tubes (like Ball, etc)

    Just to correct you on a point -- tritium tubes don't need charging. At all. They are filled with an isotope of hydrogen gas which emits beta particles, or electrons. These electrons excite the phosphor powder included in the tubes, which then emits light. This happens completely independently of any charging from an external light source.

    The tritium (whether in paint or in vials) is not the luminous compound per se, but the energy source which "fires up" the luminous component of the lume mixture.

    So any tritium-based lume - whether paint or vials - will glow of its own and does not require "charging" by an external light source.

    However, I have noticed that some of my tritium paint watches do glow brighter for a while if you charge them up with light. But they fade quickly to a constant lower level glow.
