How many DMX channels do the LOR 50 W Floods Use?

[Chris A]

I am using a F16v2 or a E682 and trying to set up the channel outputs in X-lights. I have several LOR controllers I want to use through DMX. I understand that each controller is using 16 DMX channels. It is my understanding that the 50W floods only use 5 DMX channels. So in my example my first controller would be using DMX channels 1-16 and then the flood would use channels 17-21. Can somebody please confirm I have this right.

Thanks, Chris
