That was just a first-order calculation. I presumed the maximum wattages are for the same input voltages. You can do the whole V=IR foo if you want to, but you don't know the voltages applied to the resistors or the resistor values themselves.
Krivit's picture of the control box shows no transformers, so we mains voltage was probably used.
