Using this pendant light is easy. First, make sure to hire a licensed electrician to install it according to the instructions in the box. Since it only works with candle - shaped globes, choose the right ones for the best lighting effect. As it's for indoor use only, don't place it outdoors. The input voltage range is 220 - 240V, so ensure your power supply is within this range. For maintenance, gently wipe the cut glass and iron parts with a soft, dry cloth. If there are any issues within the 1 - year warranty period, you can get a replacement. Just be careful not to be tricked by inferior products from other suppliers.
