Does it have a name plate or instructions on how to wire it? the wire that you pulled black,red or red ,blue goes to one of the fixture leads and the other color to the remaining fixture lead. green to green for your grounding conductor. As always if you are unsure consult a qualified person in order to be safe!
240 watts to 120 volts? Or 240v to 120v? What kind of meter? As in an electrical test meter?
Not unless you have 277 volts in your garage. Open the fixture and check the ballast. Some of the commercial fixtures have multi tap connections for different voltages. If 120 or 240 volt tap is present then you can use the fixture.
It could if you don't get the terminals and motor wires on the correct terminals.
Wire is wire - is doesn't matter what voltage you use. However, if you are changing the voltage on a device from 240 to 120, given the same power requirement, you may need bigger wires for the doubled current (and increased heat of resistivity).
It depends on the voltage, but if you are using it on a 240 v system, it's quite OK to use wire that can take 600 v (if you had to buy the wire, you would be spending too much).
yes
A 240 volt street light circuit is wired in parallel connections. In the base of the street fixture an inline fuse is connected into the circuit that goes up to the fixture to protect the lamp head.
Yes, you can easily use it. Just install it as you would any other 120 volt light fixture and change the bulb from a 240 volt bulb to a 120 volt bulb. It will work just fine.
Yes 220 & 240 are considered the same.
Yes <<>> In North America, a three wire 120/240 volt system uses a neutral wire. For 240 volts two "hot" wires are used with no neutral.

The terminology T8 suggests to me that the fixture is a fluorescent fixture. These types of tube fixtures need a ballast to make the tubes ignite. If you are trying to operate this type of fixture on 220 volts, you will need a ballast that requires a 240 volts input voltage source.
You don't. This sounds like a strange situation. Get an electrician.
