Using these pendant lights is easy. First, make sure you've got a licensed electrician to install them for you as there are electrical parts involved. Just follow the installation instructions sheet in the box. When using, plug them into a 220 - 240V power source. Since the globe is not included, you can choose one that fits your style. As for maintenance, keep them clean by gently dusting the iron body with a dry cloth. Don't use any harsh chemicals as they might damage the surface. Remember, these lights are for indoor use only. If you have any issues within the first year, you're covered by the replacement warranty.
