   In NON obvious ways.  Classic (edison...  8)>>) light bulbs are
   VERY VARIABLE in resistance.  At room temp they will (momentarily)
   draw/allow roughly 10x the normal current.  If in series with
   something else, as proposed here, they will 'park' at some
   intermediate/indeterminate resistance value depending on the
   current, which, here, would depend on the coil output.

   Starting point:
     100W lamp draws .9ish A once on. 120ish ohms
     At room temp (for usual rooms... 8)>>): 12ish Ohms
     surge to 10 A.

I'll not even think about using CFLs....  8)>>

And, with filament lamps outlawed, may not be best choice.
