My Wife's mother wants a install an outdoor lighting fixture on the
side of the house where there is no convenient power access.
Instead of having to run a new 110v circuit 150ft, we were wondering
about a nearby 220v circuit that feeds 1 evap cooler.
Can we branch off from one of the hot 110 v lines to power an
outdoor light using 2 90watt bulbs? will this lower the voltage of
the tapped
into hot line and cause a fault or power issue for the evap cooler?
would tapping into each hot lines with only 1 90 watt bulb. be more
viable solution. Or should we immediately stop thinking of such
ridiculous things and smack ourselves for even thinking of such
possibilities? hehe It just seems awefully expensive to accomodate
this lighting desire. Can we extend off of a 110v receptacle
circuit provided the wiring is suitable?


I'd do it in a heartbeat - IF I had a good neutral for the 220V
circuit. One hot plus the neutral equal normal 110v circuit, almost.


How about getting some 100 watt fluorescent bulbs? That would cut
your draw down on your evaporative system by 2/3 or more.

Do you mean 23-watt?


Exactly. The package says 100 watts worth of light but only uses 23
watts.


and the "watts" in an (incandescent) 100W bulb is electrical
consumption, not light output. Incandescent bulbs aren't very
efficient, so the light output is considerably less.
