It's about time, for BALL to watch out for "BALLs" from CHINA!

Don't think this Tritium tech is very state of the art already, Vostok Europe launch 1 of their divers couple of years ago with the T tubes. Lumi-Nox as well.

There's another brand, Christine Alex or Alex Christine sometime has that too, sold locally also :lol:

Anyway, what's most important to note is, Tritium is a radio-active substance with a life-span of 12 years, 12 years later, there's no more lume ;) Probably the same applies to our Lumibrite ?

Bro I thought they always claimed that the lume can go up to 25 years? :lol:

Oh is it ? Not sure on that maybe it just get dimmer and dimmer and eventually die off..

Remembering from HS chemistry class... Radioactivity is basis half-life. So, supposedly, 1/2 the material would have released the energy/particle and reached an inert state. As you say, roo7, I think it's a half-life 12 years, so 12 years from now it'll be 1/2 as bright, 24 years will be 1/4 as bright, 36 years 1/8 as bright and so forth. It's just a question of when the luminosity of the material will be indistinguishable...

Of course, HS Chem was long, long time ago.... :lol: :lol:

Ahh, a scientific explanation, so it's not really dying off immediately after 12 years, but half dead after 12 years, 1/4 dead after 24 years and so on..

So that's why they say the lume will last for 25 years.... I do wonder how long will seiko lumebrite will last.... :?:
