200AH lead acid battery
The battery (or any constant voltage power supply) will deliver a current that depends on the supply voltage and load resistance, as determined by Ohm's Law.

Incandescent light bulbs are designed to operate on a specific voltage, depending on their intended operation.  A bulb intended for 12 volt operation (for use in a car) will be instantly destroyed if you try to operate it from 120 volts.  a bulb designed for 120 volts (for use at home) will not produce any useful light when operated from 12 volts (it might get slightly warm).
