Thanks all for the replies.
Looks like I have some testing to do this weekend.
As asked for more detail. Currently I have my low voltage landscape lighting running across the deck and through the trees. There is combination of (6)5 watt led floods in the trees and (8) LED flush mount and stair lights running on the deck. (just your basic cheap big box white LED) All currently run on 12V AC transformer.
I had hoped to dig up some of the landscape wire and connect a CMD24 and add 2-4 RGB floods into the trees and shinning out into the yard. What I was concerned about was running AC current into the CMD 24.
I do have extra landscape lights, I will see if they run off a DC power supply. If not will look into the bridge suggestions.
