Overweight electrons

    I have this flashlight and it is now brighter and I changed nothing.
    So I was wondering if this is a case of overweight electrons.
    And is this typical American? Or have people in other areas seen it too?

    More likely the battery resistance decreased as the ions
    therein shifted around a bit. No electron dieting and/or
    bulking up necessary. :) I'd have to do some research
    on that.

    There is also the elementary point that someone else (your
    SO? your children? a passing fiend sporting a moustache
    and wearing a trenchcoat with pockets full of replacement
    dry cells? :) ) may have changed out the batteries.

    Contacts get dirty and the resistance goes up.

    A small jolt, as in picking it up, causes movement which breaks through
    the crud and the light brightens.
     

  4. You're sober today and it just looks brighter.

    Yes, a majority of American electrons is overweight, and a third or
    fourth of them is obese.
    Now that China's economy is developing and people can afford to eat
    something besides rice, more Chinese electrons are gaining weight.
    Was this an imported flashlight?

    When you first switched it on the electrons were probably not very
    experienced in running a torch - maybe they had been used to run a motor or
    a radio of something like that.

    However, once they learned how fast they needed to go, and how many of them
    could fit in the globes filament, they were able to work much more
    efficiently, and thus make the globe glow brighter.

    Another factor is that after a while they realsied they just didn't have
    enough 'go' and so they stopped trying to jump the contacts on the on/off
    switch when they felt like a run

  7. I think more likely the common-enough variations in human vision!

    Best example - how bright does the flashlight look in a sunlit parking
    lot? How bright does the flashlight look when it is the main light source
    in your bedroom at 4 AM?

    Actually, I think another poster has already hit upon the solution:
    dirty contacts. But your explanation also works, and one can also
    try to figure out how bright the flashlight seems to be after
    directing the beam into one's eyes for a moment. (Especially if
    the other eye is closed.)
