The way the fixture was connected originally was what we call a switch loop. The black wires are feeding power to the switch and the white from the switch is bringing the power back up to the light fixture (the white wire should be marked black with tape or painted black). The proper way to connect the fixture is to connect the white wire to the white from the source, and the black to the white (marked black) from the switch. Mr. Electric
