Don't think so different voltages...
Best wait for confirmation of someone who knows more than me though :)

NO. The limiting factor for a lamp socket is the heat generated, which is measured in watts, not volts. You cannot state that the system you propose uses only 53 watts unless you are reducing the voltage accordingly. And even then, the cooler the filament, the more current it can pass. So, even though the amount of current expressed as light may be reduced, the amount expressed as heat may be the same, or even more. Use the correct lamp.

AH!! You are suggesting that the lamp is a 75-watt "EQUIVALENT", that is produces the same amount of light as a 75 watt lamp at a reduced wattage. If the jacket states clearly that the lamp draws only 53 watts, and if it is an otherwise conventional incandescent lamp (normal or halogen), then it will be fine. Otherwise, still NO.

Use a lower-wattage lamp. Full Stop.

No it will blow. oO

If it's 120V, it will go bang on 240V, how did you end up with a 120V bulb?

With the correct voltage bulbs, when using a higher efficiency halogen bulb, what matters is the power used.

With compact fluorescent or LED, things get more complicated.
Their actual power used is much lower, so a CFL or LED will never overheat the fitting, but in a confined unvented fitting, a CFL / LED may overheat it's own electronics.
