I know that, but I 'ass-u-me'd that a full wave rectifier was used just
because it gave a smother dc supply, that was easier to filter, not that it
was there to present a "balanced" load to the line.  Plus it makes more
"power" available at a higher voltage.

Not exactly what I was looking for there.

OK.  I am trying to imagine the flow of the DC current within the big
picture involving the "offending" light bulb, a neutral and a hot wire.
What "unwanted" effect on the AC mains is obtained from the diode inline
with the bulb?  I hope I have been specific enough here.
