Hi, Have decided on 'Dumb' RGB lighting for my mini trees. These are the lights http://www.aliexpress.com/fm-store/701799/209889132-522236867/IP68-DC12V-input-12mm-through-hole-LED-channel-letter-RGB-color-100pcs-a-string.html After advise from David and eddy, I am going to need a max of 6amps to run each of these lights. I intend to run 9 sets of these lights, but am needing a controller/s capable of running them. After looking through the ACL Manual on all the different types of controllers available, i cant see anyone controller capable of controlling all the lights off one board. I have found this one thou http://www.aliexpress.com/fm-store/701799/209915969-378113147/Easy-DMX-LED-controller-dmx-decoder-driver.html If i run one of these for each tree will this be ok??? and how do I link them to the one universe as it has no output do i just daisy chain them together???
