SL also degrades over time. In my experience, in about 20 minutes it's about half as bright as it was when it was fully charged. One can replicate the charging process for SL repeatedly for ~25 years after which time it just won't glow at all.
So in 25 years time, whereas the tritium may only be glowing at 1/4th it's original brightness, it will still be glowing. The SL will not.

Which Pams have you?

I trust that is so for your eyes. I can guarantee you it's not for mine.

I tried to make a note this AM since its still dark as i awake and leave for work and the lume can still be seen in the low light conditions which aint bad considering about 6hours in total darkness.
I have the 283 which has the painted dial and the 320 with sandwich dial. I find i can always see the lume in any condition which i do like, except at 3am when i cant sleep and just stare at the time
