Using this pendant light is easy. First, have a licensed electrician install it according to the instructions in the box. You can adjust the length of the suspension rods by removing them as needed. Make sure to use a bulb that fits the E27 lamp holder and doesn't exceed 40W. Since it's for indoor use only, don't place it outdoors. For maintenance, simply wipe the frosted glass and iron parts with a soft, dry cloth regularly. If there are any issues within the 1-year warranty period, you can get a replacement.
