Why are my Edison bulbs turning black?
Why does a light bulb turn black? Over the life of an incandescent light bulb, the filament begins to deteriorate and the particles will settle on the inside of the glass. In return the bulb will take on a grayish appearance and a slight decrease in light output may occur.

Can lightbulbs last forever?
Typically (depending on use), incandescent bulbs will last for about 2,000 hours — that’s usually less than a year if turned on 6-hours a day. … The main reason is that the filament in regular bulbs is made of tungsten rather than carbon, as in the “Centennial Bulb”.
Why did my light bulb burn out immediately?
Habitually loose connections, either at the socket or with the wire connections, can burn out the bulb quickly, as well as cause flickering. These loose connections increase the electrical resistance and the heat passing through the filament of the bulb, which can shorten its life.
