why do lightbulbs seem to go bad only when being turned on?
The filaments in the bulb get thinner and thinner with more use. At some point they are thin enough that the surge of electricity when turning on the bulb is more than the filament can take.
The Short Answer
The filaments in the bulb get thinner and thinner with more use. At some point they are thin enough that the surge of electricity when turning on the bulb is more than the filament can take.
