How do you know whether to get 120 volt or 130 volt light bulb?
Choose a bulb with the same voltage as your fixture to prevent damage or risk of overheating. If the fixture specifies 120 volts, use a 120-volt bulb. If in doubt, consult the manufacturer's instructions or a professional electrician.
Can you use 220 volt light bulb on 120 volt system - I know the reverse would probably blow the bulb so wouldn't European 220 Volt do ok in 120 volt socket or would it be dimmer than it normally would?
Yes a 220 volt light bulb will run on a 120 volt circuit but at 1/4 of the wattage that the light bulb is rated at. A 100 watt light bulb on 220 would would be equal to a 25 watt light bult on 120 volt system.
How many 1.5 volt batteries does take to light up a big light bulb?
It depends on the size and wattage of the light bulb. In general, a regular household light bulb would require more than one 1.5 volt battery to light up, as most standard household light bulbs operate on higher voltages (typically 120 volts in the US).
Can a car battery light up a 60 watt regular light bulb with out using a power inverter?
Yes it it is a 12 volt DC light bulb. It will not operate a household 120 volt light bulb.
Does a 9 volt battery light a light bulb?

It is not recommended to use a 130 volt light bulb in a 120 volt socket as it may cause the bulb to burn out prematurely or even pose a safety hazard. It is best to match the voltage rating of the bulb with the voltage of the socket to ensure proper function and safety.
