Ark,
Current is Power(watts)/Volts. A 60 watt lamp needs .5 amp at 120 volts. A
120 volt inverter will draw 5 amps + efficiency losses to run that bulb. A
100 watt lamp will need 8.3 amps + from a 12 volt supply regardless of
whether the inverter is 110 or 220.

I try not to modify, drill holes, etc. I brought with me from USA a dozen
120 volts "economy" fluoresent lamps and 12/120 v inverter.
A lamp with 60 watts output draws 1.2 amperes. A lot of light! I even use
occasionally 100 watts lamp.
In Portugal I bought 220 volt Philips super-light bulbs. A 75 watts bulb
draws .90 amps. I run my bulbs with 12/220 volts  inverter.
Excellent quality , pleasant color temperature light. I will wait till LED
will be much cheaper.
I think these days inverter assisted lighting is a very good alternative.
