Installing Led outdoor light with 2 wires only

Hello everyone, 

I recently purchased an outdoor LED hanging lantern and tried to install with poor results. I initially thought the light was defective so I exchanged 2 others, so I dont know what to make of it.

The light is LED with a dusk to dawn sensor. The strange part for me is that the fixture has only two wires; a thin, bare wire and a black double strand (fused together) wire. My box has a single black wire, a white wire and the bare wire. The fixture that was there before worked fine, I just wanted to upgrage. The old fixture had wires identical to the electrical box, but the new one is totally different. The house is about 50 Years old.

Current does not know the color of a wire. LED's use DC (Direct Current), just like your vehicle, not AC(Alternating Current), Just like what is coming into your home. So it does not matter. You have 3 wires. Pick one to connect to the neutral, pick another to connect to the power. And bare always connects to ground.

The fixture that was there before, uses AC. That does matter. A power, neutral and a ground.
