It should not be too hard to find u-bolts at a local hardware store that are slightly larger than the pole diameter you currently have installed. drill out the rectangular plate that comes with them and bolt surfce mount lights to pole. If the pole is 4 inches in diameter or more, I would use glavanized heavy duty self tapping screws and just mount a surface mount plate directly to pole, usually a 1/2" thread, for a standard mr-16 spot and use a 12" extension from the plate to get the light out a bit farther. I would run the LV wire in a seperate 1/2" galv. steel pipe going up to the light and bury 6" in the ground to protect wire from mower and weedeater.
