Thats a tough one to light on the right side from the bottom. How did it look in the demo. I asume you placed the lamp just to the right of the rail, but probably had a pretty good shadow. Have you considered down lighting from the soffit above? I know it is less dramatic and it will not get the arch and upper gable but the light will be even on the fluted columns. If I was then going to light up the interior of that arch. I think the only approach to do that would be to run my wire under that white stucco bond line that is running horizontally along the lower part of the walls. You could maybe adhere and hide a 14g wire under that bond line and run to an individual light placed in a flower pot, placed next to that fluted interior column. That is about the only way I could think of to get even light distributed on that entryway. 4 fixtures, 2 up and 2 down. Just my .02 though. Mike, after you attatch the wire; paint it white to match the stucco and you would probably never notice it unless you stuck your head down there to see it.
