Good afternoon. I have a small landscape lighting system consisting of 4 LED lamps in a semi circle around my front yard flower bed. I am in the process of building a small rock bubbler fountain system in the middle of my array of landscape lights. I was asked by my spouse to make it so that the perimeter lights could shut off at a certain time, but leave the lights on that will accent the fountain. I'm not sure how to accomplish this without purchasing a separate transformer just for the fountain lights. Is there such a thing as a low cost multi-zone transformer that could accomplish this task? Any suggestions would be very helpful.
