Long time lurker, first time poster. I'm wanting to add some additional RGB elements this year and each element is going to require 2 dumb 5050 RGB strips 30 leds/meter. I've used the holidaycoro 3-channel controllers on one strip with no problems. I was wondering if one holidaycoro 3-channel controller will feed the two strips? If they can should the controller be placed at one end or in the middle of the 2 strips? Would these y-adapters be useful? Just want to be sure I order enough stuff (with a couple spares of each). Appreciate any help/advice.
