Not true at all... wattage does not determine the internal resistance of the bulb, so put a hold on the bow for svxfiles!

Mr Ohm got it right! In a fixed voltage situation, the internal resistance of the bulb determines the wattage, not the opposite as you stated, Trevor.

Increasing the voltage, which is not a part of this equation because we have a fixed voltage sourse, would increase the wattage but not necessary proportionally to the voltage increase, because of the composition of the filament in the lamp.

A bad connection that causes heat on a contact, actually will add resistance to the then-series circuit, thereby reducing the power which is measured in watts.

Trevor, you should also know these facts.
