The life duration of a light bulb depends on the thickness of the filament. If you make it thicker the lifetime goes up, but at the same time the brightness goes down. This means you spend more money on power for less light output. Look at this lightbulb that burns for 100 years or so in some fire station, it’s hardly brighter than a candle.
