I really wish people would stop saying a light is burning.
The light is TURNED ON.
It's NOT BURNING....
I once heard that some guy called the fire department because someone
told him his porch light was burning. Whether this is true or not, I
donrt know, but I dont doubt its true considering how stupid some
people are, but that term "light is burning" is really assenine. If
it was burning there would be flames.
What is happening with that tungsten element? It is heated to the point it
glows and then burns through doesn't it? You do not need huge flames to be
burning. In the enclosure, it burns very slow compared to a bulb with no
glass where it burns out in seconds.
FYI: The tungsten does not burn.
It glows because it is really hot. Eventually enough of it evaporates
into the gas in the bulb so that one part heats even hotter. It then
melts, boils and causes a break.

I think you can do that, but then you need to remove all the air from
the bulb and seal it.
Actually, some bulbs seem to fix themselves. I've seen it
occasionally, mostly in C9 holiday lights. There is life after death,
at least for those light bulbs. The light will be brighter after
self-repair, since the filament is shorter now and so has lower
resistance (notice that it's whiter too, because of the higher
temperature). It goes out again quickly. That's how I know that if one
bulb in a group is brighter than the others, it's about to die again.
What happens when the filament reaches the end of its lighting life? It
doesn't turn off. It burns out. So common terms go.. Also things can
burn and not have to flame. Your chain of thought is a bit of track.
This just isn't my day. I went to the fridge to get a beer and found
the fridge was running. I chased it for several miles but it got
away. I finally got back home and found the toilet was running.
Chased that damn thing for over an hour and got all muddy in the
process, but never caught the toilet. Got back home and wanted to
take a bath. Guess what, the tub was running. I let it run, the hell
with it. Thank God beds dont run..... Goodnight !!!!
