I've been playing around with some DMX and RGB controllers for awhile, but I haven't been able to figure this out: If I look at a controller like the following: http://www.holidaycoro.com/3-Channel-DMX-RGB-Controller-p/26.htm It says "2 Amps per channel". To me that would be mean I can have 2 amps on Red, 2 amps on Green and 2 amps on Blue. So if my LED strips is set to "White" that would be 6 amps. Well now, if I understand things correctly, the common line has 6 amps on it. Is the correct and is that ok? Or do I need to assume I can only use 2 amps total for the RGB so like .67 amps per color?
