Is this an old message spat back by another machine, or is this
really coming around again?  These devices exist.  They're called
diodes.  Simple (not full-wave) diodes packaged in discs to go at
the bases of light bulbs are available from almost all cheap mail
order catalogues, or at your corner electric hardware store.  The
mail order calls them "Light Savers" and charges ~ $2.50 per.

[Yes, diodes still spike @ 60/sec; but they do save the bulb life.
Maybe the "Light Saver II" has a full-wave rectifier or an LC
smoother in it.  I've never cracked one; I was told a long time
ago what was sposed to be in it.]
