Just use the Bars style....its really all you need to know how the channels are set.
For Floods and Spots you don't need anything special they are like a normal 3 channel light and if they do have anything special just use a standard moving head style and it just won't move.
Attached is an example of a Flood graphic. Do that with a Single Line model set to 1 node. Change appearance to something larger. For this I used Size 300, Blended Circle, 30 transparency.
