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?

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.
