Use a European halogen electric light fixture in the U.S.
The 300W  bulb draws up to 3kW peak when cold.  When reducing voltage from 230 to 120 the same wattage doubles current. Most likely something did not handle the excess heat from higher currents.  ( triac dimmer? or switch?)

The  2.5A fuse must be doubled for same power at half the voltage, but can the wiring and switches support that?  Maybe not.  The H suffix means time delay or "slow-blow"

Are these the long halogen tubes? 119mm EU is compatible  with 4.7" US
 (same)

@Winny 's warning is true for Edison style screw base because the 1mm difference between the threads of E26 and E27 can cause unsafe higher resistance contacts that rises with aging and oxidation of heat.
