I started putting up the light bars around the center peninsula. I wanted to keep the heat and amperage to a minimum. Did some experimenting with a variation of Joe Fugate's single bulb idea, but used compact fluorescents instead of incandescent bulbs. I can use a 13W CFL to get 60W of light. I tried them every 24" end seemed to have a good bit of light.
I came up with a framework that would also work as something to attach the upper fascia to. It just takes a while to mount individual octagon boxes, and wire the lights in series.
