A long time ago, SOME of us learned that constantly turning-on and

This is bull****. Turning on and off an incadescent light does not
use more energy, and if the off period is more than a few seconds,
energy will be saved.
Worse than that. AC incandescent lamps acturally turn on and off
60 times a second. :-)
