I have a 220 volt line that powers my pool pump. I want to run 110
volt lights near the pool pump and would like to convert 220 to 110.
Is this as simple as taking the 220 wires, and connecting only one hot
wire side with the common wire and ground wire to a standard 110 volt
outlet?

Suggestion: If all you need is a convenience light 'near' the pool it
may be possible to use a transformer. The transformer would convert/
step down the 220 to 110 volts to feed a conventional lamp. A
transformer for say 100 watts would not be too expensive or large. The
metal frame of such a transformer and the box it is mounted in should
be grounded for safety. The output of the transformer could have
switch to control the light. But again everything should be wired/
mounted in standard way to conform with approved electrical safety and
insurance practices.


Far cheaper to buy 220V lightbulbs.

Or just put two 120 volt bulbs of the same wattage in series across the
240 volt line. G

It's likely not to code, but thinking about it, each side of the 240
volt circuit is only 120 volts above ground, and for a zillion years
table lamps didn't have polarized cord plugs, so there was a 50-50
chance that the threaded portion of the light bulb sockets in them were
120 volts off ground.

While several people have pointed out you should never use a safety
ground as a return, the OP did not say that. He uses the word common,
a term sometimes still used for neutral. He therefore may or may not
have a safe way to do this. He says common wire AND ground wire,
implying he has both available.
