I know this is an old post but just in case anyone else comes across it I thought I would post my experince with it. Yes it works, I tried it first I only connected the LS100 to the LED1 port on the commander pro, then I went to the corsair software also known as ICUE and set the LED1 port input as RGB strips, then I had to select the number of LED strips I had connected (maximum is 6) so I selected maximum but the strips didnt all light up only 1.5 lit up, so I created a loop that started at LED port 1 and ended at LED port 2 (this could easily be done using the cables that comes with the LS100 and now it works like a charm. Haven't gotten any dimming or LEDs that dont work and im currently using 3 ll120 rgb fans and 7 ql120 rgb fans through the commanderpro.
Step by step
So lets say you have 4 LS100 RGB strips - You would procced to take one of the included power cables, plug it into your commander pro LED port 1, then at the other end of that cable you connect one LS100 strip, followed by another and another and so on, once you run out of RGB strips you take the RGB cable thats included which has the same RGB adapter in both ends and plug one end into the last LS100 RGB strip and the other end into the LED port 2 on the commander pro.
