The difference between the voltage of lights

This is going to be a noob worthy question.

What is the difference between a 120V and a 220V tungsten light? Does it have any effect on the temperature or the brightness of the light? Apologies for my ignorance! lol

The two bulbs are not interchangeable. One is designed to be used with 120v service which is common in the US. The other is designed for 220v service as is found in Europe. Plug the 120 into 220 service and watch the bulb go pop. Plug the 220 into 120v service and it will light, but be very dim. I've never tested this, but I'd guess if you compare the output of a 120v, 1000 watt bulb with a 220v, 1000 watt bulb they'd be similar.
