our 2car garage right now only have a two-socket outlet on the ceiling (one outlet used up by the garage opener), another outlet in one wall, plus a switch for a scew-in light bulb. I want to add some shop light to the ceiling after we settle in. at first i thought about just plugging a powerstrip into the one available outlet in the ceiling and plug the shop light in there. then I realize I have no way to turn it on and off convinently. how difficult is it to add a new switch that'll control say 3 or 4 shop lights? I do have the black and decker home improvement and home repair books, but its lost in the garage during the move and i don't know where they are.
