Using this pendant light is easy. First, make sure you have a licensed electrician install it following the instructions in the box. The light works with a 220 - 240V input voltage, so ensure your power supply matches. You'll need to buy the globes separately as they're not included. Just screw them into the 3 E27 lamp holders. It's only for indoor use, so don't put it outside. When it comes to maintenance, keep the glass clean with a soft cloth. If any part breaks within a year, you can get a replacement. Remember, always use the right wattage bulbs to avoid overheating.
