Using this pendant light is simple. First, make sure you have a licensed electrician install it as per the instructions in the box. Once installed, you can use any E27 globe that suits your needs (the globe is not included with the product). This light is only for indoor use, so don't place it outdoors. For maintenance, turn off the power before cleaning the iron shade. You can use a soft cloth to gently wipe away dust. Remember, the warranty is for 1 year, so if there are any issues during this period, you can get a replacement.
