I think you have something backwards. A 240v load moved to a 120v circuit should draw half the current or 1/4 the power. Wire size should be fine. You'll have less power than you are used to.

This is true if it's a resistive load. If it's an electronic load (switched psu with 110-240V input), then the load will be the same and the current will be double.

In other words, it's a valid concern for OP, but not necessarily for a low power light bulb.

It's not the same load though. If you cut the voltage in half but consume the same power (because you switched from a European 5W bulb to American 5W bulb) then current needs to double.
