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?

Why isn't this your first choice, since it's straightforward and done
all the time? I hope you intend to use an electrician for the actual
No offense intended, but you don't seem to understand this stuff well enough
to do it safely. Please hire a pro, or at least get hold of a few books so you
can learn how to do it right. Improper wiring can kill.

Yes it can be done, BUT. You need to make sure that that 240V circuit
has a neutral as well as a ground included (at least four wires) As the
others have suggested, I will also. There are a few possible glitches that
may come up and you may will miss one and end up with a dangerous situation
if you want to do this yourself. I suggest hiring a professional. Also
make sure you get a permit, it would not be good to find out that your home
fire insurance will not pay off because of un-authorized wiring.
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.
Lumens is the measure of light output. Watts is the measure of
electrical energy you're putting into the thing. What they're
saying is that they put put the same light (lumens) as a 100W light
bulb while consuming less than 1/4 the electricity.
Look at the lumens of any light bulb and compare that with the
