Sleepyhead, I used the screw mount with stainless steel screws.
Columns, I ran the wire in the gutter. I drilled 2 holes. 1 above the gutter through the facia down at an angle into the soffit cavity. I then drilled a 1" hole in the soffit and chased the wire from the gutter out through the hole in the soffit. The fixtures are Vista 2116 copper directional spot with a 20w BAB bulb and frosted lense. I mounted the fixture to a round copper flush mounting canopy.
