Ok, I can understand that watts (roughly) amps * voltage * some other factor, so I can appreciate that the same wattage is obtainable via different values on the RHS of the equation.

But what I'm still unclear about is this starter business. "Designed to be used with a starter." Do they not all come with a capacitor anyways? Or is that different? What is the starter? Does it come together with the ballast or is there a different part # for it and it has to be ordered separately?
