Using this pendant light is easy. First, find a suitable indoor location to hang it. Make sure to get a licensed electrician to install it as per the instructions in the box. Once installed, you can screw in a compatible E27 bulb (up to 72W) to light up your space. Remember, this light is for indoor use only. Don't try to install it outdoors. For maintenance, simply turn off the power before cleaning the glass and iron parts with a soft, dry cloth. If there are any issues within one year, you can get a replacement as per the warranty.
