Considering the voltage difference between Europe and North America, will an E27 base bulb, in Europe, emit the same lumens as an E26 bulb in america?, Or will there be a different output because of lower American voltage?

Your question is whether the voltage will be a factor. Provided you are talking about different bulbs each built for the local voltage, it will not be a factor.
What makes any bulb emit light is power (in watts), not voltage or current.
Power = Voltage x Current, so for any change in voltage, there's a change in current that will make it the same power. Halve the voltage, double the current for the same power.Lumen is an international unit so a lumen means the same thing everywhere.
