This fixture arrived with wires pre-installed. Otherwise, this would require two experts to be able to set the wires so the fixture would rest level. So the good news is that this fixture is easily installed by homeowners. However, measure your space to be sure you'll be happy with the height of the fixture. I have 9" ceilings, so this fixture is a bit high over the dining room table. However, we want a large light spill (the area bathed in light) so we can read and use iPad at the table so this works for us. If only a dining room, I'd want to hang this several inches lower.
