How do I connect a new light fixture that has two black and two white wires?
Combine the 2 white from the new fixture to the white from the box, then connect the 2 black from the light to the black in the box, last connect the bare ground in the box to the metal strap that the lamp hangs from, If there is no metal strap or the new fixture is not metal tuck the bare ground up in the box and mount the new fixture.
