I am planning on getting into the outdoor lighting. My issue will be multiple locations, I have three locations that are far part and across the grass so i cant run the low power extension cords. The base power supply looks to only come with the set of three spot lights or the one pathway light. I want to run two spot lights in one location and 1 spot in another location and then 1 spot and maybe a couple pathway lights. Where can I get just the base power supply?
