mm Close. I get .096 watts with one that has a 150,000 ohm resistor in
series with lamp. So if the utility KW cost $ .10 you can figure out the
rest. WW

This would be about 9 cents a year, if the light is off all year.

Much less than the stand-by power a wall-wart uses even when nothing
is plugged into the wall wart.

Power supply (AC or DC) that plugs into the wall and has a cord that
attaches to an electronic gadget.  It's a bump on the wall, hence
"wall wart".
