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.
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 can be if you connect two same watt lamps in series with each other. The 240 volt supply will drop 120 volts across each lamp.
The question is "use less of what?". If they are both the same wattage the 240 V light will use 1/2 the current of a 120 V light.
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!
Slightly dimmly
Yes, it can be connected safely but the lamp will not emit any light.
The metal halide light is a commercial fixture. Wire it to 120 volt. 277 volt is the star point voltage of 3 phase 480 volts. Likewise 347 is the starpoint of 3 phase 600 volt. By wiring it to 240 volts the voltage might not be high enough to ignite the lamp. Try it and see, it won't do any harm to the fixture. Make sure that the wires that are not connected are taped off as there will be voltage on them.
240
I found this light http://www.ecolivingcentre.com.au/products-page/?product_id=23 and it is the perfect size and power for a torch we are making in graphics, the only problem is that it runs on 240 volt ac current and the torch im going to make is going to have a 12 volt dc lead acid battery, is there any way that you can make the battery work with this light
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.
