And yes - you really really need a ring light. We found that green is a good option, since it's not a hue that you usually see elsewhere on the field.
We did that too and honestly it tends to be our favorite way to go with vision processing so long as we don't have a coprocessor. Vision processing is eating the cRIO alive, and considering the default robot/Dashboard code already sends like 2 or 3 int/bool values from the SmartDashboard to the robot, sending the X/Y relative coordinates of the target, the distance from the target in ft and whether or not the target is in the center of the frame in bool shouldn't be such a problem as far as bandwidth is concerned
