Using this pendant light is easy. First, have a licensed electrician install it following the instructions in the box. It's designed for indoor use only, so don't place it outside. When it comes to the globe, you need to buy one separately with a maximum diameter of 70mm that fits the E27 lamp holder (max 40W). You can adjust the length of the suspension rods by removing them as per your needs. The rod can tilt up to 30 degrees to suit your lighting angle. For maintenance, gently clean the frosted glass with a soft cloth. If there's any problem within one year, you can get a replacement.
