Using this pendant light is easy. First, make sure you have a licensed electrician install it according to the instructions in the box. Once installed, you can simply screw in a compatible E27 bulb (not included) and turn on the power. Since it's for indoor use only, don't place it outside. When it comes to maintenance, turn off the power before cleaning. Use a soft, dry cloth to wipe the iron surface. If there are any issues within a year, you can get a replacement under the warranty.
