Whistling light bulb

The last time this bulb will work. The filament has broken but the electricity is arcing. Switching on again would only be possible with more than UK 240V AC. It is a 100Watt Silver Crown Bayonet fitting type bulb, and if the government had it's own way these would be banned for heating our homes, and let's face it, it is a cool climate anyway.

The lighting circuit was fuse protected. A fuddy duddy circuit breaker would probably trip out

[jovicakluk]

thats bull shit the light bulb would imeadiately melt if this were to happen

[thomasking55]

why?

[Arabhacks]

The light bulb is not arcing, the filament is oscillating.

The coil of tungsten wire can act as an electromagnet and vibrate.

Some otherwise normal light bulbs can be made to vibrate by placing a powerful magnet near.

The flicker bulb, where the filament wiggles back and forth, have a magnet inside.

@laurdy actually they are still better for the environment as most coal power plants spew out mercury to power the old bulbs

It has been turned into an arc lamp. Try feeding with a higher voltage...

@thomasking55 i Think what jovicakluk is saying is when the Bulb Filiment breaks and continues to light...normally a High Current would cause the Fuse Wires in the Bulb to melt...but in your case the Arc is small enough that the Current Drawn by the Arc isnt high enough to melt those Lead Wires.

those cfl's are worse for the environment than the normal type because they contain mercury, and take more energy to make, some also cause radio inteferance on the AM band, i've even had a cfl explode i my bedroom and i've heard of them actually catchng fire

It's gonna pop o;

[SmashCOBamberg]

it's dead

Gah, I'm sick of this - mine keep "singing" as well sometimes (not a filament damage as they "sing" even straight out-of-the-box), and it's kinda annoying. Also with a dimmer I removed by now (didn't cut much of the noise however) it kept sounding even louder and the bulbs kept blowing up from time to time, no matter I usually set the dimmer to the max anyway. Afaik my light holder construction has been removed from the production lines due to the internal electrical issues however.

Put a dimmer on a lightbulb and it'll sing to you also.
