NOT TRUE.
In simple terms Watts = Voltage x Current.
For the same Voltage Level - say 110V for a USA source - the
higher the wattage the more current is used.

Then goes on to say:
> The 60 watt bulb has higher resistance to the
> electricity than the 150 bulb

EXACTLY.
Higher resistance = less current for the same voltage level.
