Luminova, SuperLuminova and Chromalight

[Asumer]

I had a technical question which I couldn't find the answer to and maybe some forum members may know.

Basically I am wondering how long luminova, super luminova and chromalight will last for, tritium is known as only having a shelf life of 12 or so years. I know the non-radioactive newer alternatives last alot longer but am curious how long.

And I have heard that the oldest of the trio - luminova does not shine as long as it originally did when purchased new. Curious what owners of all three can expect for nighttime dial reading and if and when they would need to be serviced to restore the original glow(brightness and duration).
