What has gone unsaid is that a yellowish bulb gives the subliminal
impression of warmth. By dropping the voltage across the lamp
filament, you can fool the building occupants into turning down
the thermostat in the winter. This saves on heating oil, gas,
coal or electricity. Thus, it's obvious: a diode or series
wiring saves energy during cold weather. During the summer, just
boost the voltage up a tad and they'll be turning off the A/C and
putting on sweaters.
