Ticking with dustsucker against lamp makes lamp brighter.

Define "ticking against it"

don

Doesn't your lungs hurt?

Are you bumping into it with your mouth that is causing the filiment to vibrate?

I've noticed the same effect when I *wipe* the dust off!

Too bad that "trick" does not work for YOU...

Accidently, or deliberate tick with hose against lamp pole...

Doing it repeatedly makes the lamp shine brighter and brigther until it pops dead.

(Philips lamps)

Bye, Skybuck ;) :)

Nope, I with my vacuum cleaner ofcourse ! ;) :)

Hose might be doing it. Would vibration in the lamp be bad ?!

Is this a conspiracy by Philips to make the lamps pop when a car/truck drives by ? ;)

Bye, Skybuck.

Q:: Why does a lamp start shining brigher after.....

A: To get to the other side, of course!

Note: That answer is at least as asinine as the vast majority of your posts on SED.

Another question: Are you retarded? (or whatever the politically correct term is these days) Seriously. I think some of us start to feel bad picking on you all the time.

Maybe you slowly short the turns of the filament with each tap, until it finally burns up?

This illustrates the reason for rugged or rough service lamps, which are used in portable drop lights that might get banged around or experience shock and vibration from hammering, drilling, etc. Such lamps are built with more filament supports so the hot filament does not stretch and eventually break. Mechanical shocks while the filament is incandescent might cause some turns to short out and thus cause more current and higher brightness.

Phase out incandescent lamps and use CFLs. Even better are LED lamps, and they are very rugged and should last just about forever, but I've heard of some limited lifetime issues, mostly due to phosphor coatings deteriorating. I don't think that's an issue with white LED clusters that are composed of red, green and blue. They also have the advantage of being adjustable for color temperature.

The old lamp was near the end of its life. The filament was thin and very weak, so any vibration caused sections of itself to touch, shorting sections out. This increased the lamp current which burned the remaining parts of the filament out.

Smack yourself in the head with it.
