HFguy makes claims by violating what was taught back in Junior High
school. Without first learning underlying principles of how a light
bulb fails, instead, he has proclaimed based only upon observation and
wild speculation. He ignores junior high school science to promote
speculation as if it were fact. Such reasoning also proved Saddam had
weapons of mass destruction.

Snip

Here is a fact for you;- you sir are a known Troll in at least several
news groups. You could say that you are a weapon of mass dissension.

Please keep the same handle so you stay in the kill file.

Any bulb will burn for decades if the voltage is low enough.

Also the fact that it's been on continuously. Incandescent light bulbs
seldom burn out while they are on, unless dropped or hit. Failures are
caused by the current surge when it's turned on. However they must have
had power failures during the many years the bulb has been there. I
wonder how they protect it from surges when the power comes back on.


The filament has high resistance. The current never gets high enough
to stress it. I'm surprised it survives earthquakes.

From the 'Great Internet Light Bulb Book':


-WHY BULBS OFTEN BURN OUT WHEN YOU TURN THEM ON-

Many people wonder what goes on when you turn on a light. It is often
annoying that a weak, aging light bulb will not burn out until the next
time you turn it on.
The answer here is with those thin spots in the filament. Since they
have less mass than the less-evaporated parts of the filament, they heat
up more quickly.
Part of the problem is the fact that tungsten, like most metals, has
less resistance when it is cool and more resistance when it is hot. This
explains the current surge that light bulbs draw when they are first
turned on.
When the thin spots have reached the temperature that they would be
running at, the thicker, heavier parts of the filament have not yet
reached their final temperature. This means that the filament's
resistance is still a bit low and excessive current is still flowing.
This causes the thinner parts of the filament to get even hotter while
the rest of the filament is still warming up. This means that the thin
spots, which run too hot anyway, get even hotter when the thicker parts
of the filament have not yet fully warmed up. This is why weak, aging
bulbs can't survive being turned on.

Where'd the ''thin spot'' come from?

From the wire overheating and vaporizing the filament.

The higher the Watt rating the lower the internal resistance.

I found it! It was looking right straight at me all the time.My old
General Electric A-C Volts meter,that is.(the meter itself is in a
little old style grey metal cabinet,I guess it dates back to the 1940's
or 1950's,but it still works as good as new) It was sitting on a pile of
junk on top of my bigggg olddddd antique trunk (can't see the tree for
the forest is the way it is my house) near my dining room/kitchen door.

(so was my Battery Cell Tester.MAC Quality Tools.Battey Cell
Tester.ET2007.Mac Tools,Inc.Washington Court House,Ohio 43160) I plugged
it in the wall outlet by my couch (oooops,Blueberry doggys couch) and it
is showing a rock steady 120 volts (the needle isn't wavering at all) on
the nose.Nothing wrong with my elecstwicyty here that would be causing
my 60 watt G.E.Reveal incadescant light bulbs to be blowing out.

I think the biggest problem is the fact that it's a G.E. bulb. They
make crap.

There used to be a G.E.factory here in Jackson that manufactured
incadescant and flourescent light bulbs.When my old buddy got out of
active duty (U.S.Navy) back in the mid 1960's,he worked there for a
couple of years,then he got a job delivering the U.S.Mail.(he retired
from the U.S.Navy Reserves unit here in Jackson [about 30 years or so]
and the U.S.Post Office too)

I dont believe G.E.makes crappy light bulbs.I own quite a few old
G.E.tube type and transistor radios and most of them work ok.I will keep
on buying and useing G.E.Reveal 60 watt incadescant light bulbs as long
as the stores keep on selling them.By the way,I noticed they sell very
well at the local Jackson stores around here,even though there are tons
of flourescent light bulbs sitting next to the G.E.light bulbs on the
shelves.(in Jackson,we like REAL Light Bulbs)
