At what voltage? Until you tell me the voltage I can't give you an answer.
To find out Amps you need to divide the Watts by the Volts.
At 120V you have 0.4 amps. At 12V you have 4 amps.
You could do so, but from safety perspectives it's better not to do so. A 50W bulb will draw a higher current from the grid, which the 45W fixture is not designed for, so it might break down.
The equation that you are looking for is Amps = Watts/Volts.
50. Is this a trick question?
LOL
A 65 Watt incandescent light bulb should draw 65W/120V = 541.67mA
Halogen gas is in a Tungsten-Halogen Light Bulb.
1 amp
Halogen is a gas, so your question doesn't make much sense. If you're asking about a halogen (light) bulb, then the answer is: mainly halogen.
Fluorescents are always 3-4 times more efficient than halogens which are a version of incandescent bulb.

It's 75/120 and the answer is in amps.
1 amp
It can, but if you're wanting to run a 120v light bulb on DC, you'll need 120v DC to get the rated output. That's a lot of batteries. It's easier, and more sensible, to find a DC rated light bulb, such as an RV bulb.
Halogen light bulbs are made in a variety of sizes to meet different needs.

About 0.6 amps for a 12v 21w bulb
The amps (ampiers) decrease when in a series circuit ( with a light bulb)
Without knowing the voltage, I can not tell you how many amps a 60 watt light uses. If you have a 12 volt system in a car, then a 60 watt light will pull 5 amps. If you have a 120 volt system in a house, then a 60 watt light will pull 1/2 amp. If you have a 240 volt system in an industrial building, then a 60 watt light will pull 1/4 amp.
The formula you are looking for is I = W/E. Amps = Watts/Volts.
