The LE will start responding to the channel that you set it's first channel to, and go for 16 channels from there.
It doesn't care if you start at 1 for the first controller, and start at 200 or even 4 for the second. Some folks "overlap" their controllers' channels on purpose to do a special effect, or control more lights than one channel can handle.
So you can have the first LE @ 1-16, and have the second at 201-216 if you want.
