You should use a proper power supply. Arc lamps explode or melt if they're not powered correctly. The power parameters aren't trivial; they have to be looked up in the lamp's specifications.
You cannot put DC through a transformer. If your lamp is using the mains voltage, there is something called an inverter. A minimum size 100 Watt inverter to the mains standard for your lamp should work for you, if this is a 70 Watt lamp. Doing it this way would be much less efficient, and more costly than having a 70 Watt 12 Volt lamp in the first place.
--- You buy a 12 volt, 70 watt Metal Hylyde lamp and you connect it to the
12V source, which should be able to supply at least 6 amps when the lamp is hot and probably close to 60 amps when the lamp is first turned on.-- John Fields
