I haven't seen many duals that are separately controllable, so when you plug it in, both bulbs will fire. While some of the dual ballasts have a switch for each circuit, they typically only have one mains cord so if you wish to use a timer, your options are limited. With separate ballasts, you have the option of putting each on its own timer, with the disadvantage of more bulk.
