volts times amps = watts

So, you can say that the 110 volt circuit, times 20 amps = 2200 watts.

Hint: Try using flourescent, or compact fluorescent bulbs. They use a lot
less power.

At a lower power factor... watts = 0.4 x volts x amps,
for some undercounter fluorescents.

Do fluorescent lights have a power factor? would
like to know. But, that said, if the undercounter
light fixture say 15W, then that is how much is
used regardless of power factor and w=va still
applies. or am I wrong and the labels are incorrect.
