Please excuse this first time poster with what may seem like a stupid question, but I don't actually know what I'm searching for, so I'm sorry of there is a post for this already.
I'm looking at creating myself a Adalight rig for my XBMC media system, http://learn.adafruit.com/adalight-diy- ... g/overview
Simply put, the post covers only a single string of lights e.g. 25pcs strand. I have a 50" TV and I figured Ill need at least 100 RGB LED's. My question is this, can I join 4 x 25 strands? If so could I run then off a single 12V 2Amp 110-240V power pack? If so is the distance of cable between the LED's important (not suggesting meters, only if it must be exactly the same all way round the circuit) or is it IC controlled when it comes to signal.
