As a general answer, dimming. Incandescent bulbs are fantastically sensitive to applied voltage; Wikipedia's article on the subject (https://en.wikipedia.org/wiki/Lamp_rerating) notes that bulb lifespan is inversely proportional to the applied voltage to the fourteenth power or so.

In an ordinary home you can't directly reduce the supply voltage, but dimming a higher-rated bulb will get you somewhere in the ballpark through a reduction in the duty cycle.

However, this comes at the expense of luminous efficiency. Reducing the applied electrical power reduces the filament temperature, and the black-body spectrum of a lower-temperature filament has proportionally more output in the infrared region.
