Rewiring Ceiling Fixture

Long story short, my current ceiling fixture neutral was damaged so I decided to just replace the existing knob and tube wire.

The fixture has two wires (both covered in a gold coating) with a ground wire coming out of the fixture itself. The knob and tube wire that was coming in was just two wires. I am assuming a hot and neutral, the ground was not being utilized.

Am I correct in assuming that I can run 12/2 wire from my breaker box to the switch and then 12/2 wire from the switch to the fixture?

If this is the case how do I wire the switch? The two hots together and the 2 neutrals together, with the ground alone?

12/2 between a breaker and a single fixture is a waste of time and money.

The math ----- Power ( watts) = amps (20) X volts(120)
= 2400 watts ; certainly over-kill for a 150 watt single-fixture load.

I advise you to tap off a 15 amp multiple-outlet circuit , such as the basement liting.

I agree with the waste of a 20A circuit on a single fixture...

Wirenut the two grounds together with a short piece (pigtail) of bare wire. Connect that pigtail to the ground screw on the switch.

Wirenut the two white neutrals together.

Put one black hot on each pole of the switch.
