Using these pendant lights is easy. First, find a suitable indoor location to hang them. Since they need to be connected to a 220 - 240V power supply, make sure the voltage in your area matches. Don't forget that you'll need to buy a globe separately as it's not included. The lights come with a 3000mm PVC cable for suspension, so you can adjust the height as you like. When it comes to installation, it must be done by a licensed electrician. You'll find an installation instructions sheet in each product box. To keep your lights in good condition, wipe them gently with a dry cloth from time to time. Avoid using harsh chemicals. If you encounter any problems within the 1-year warranty period, you can get a replacement. Also, be careful not to confuse these high - quality lights with inferior similar products from other suppliers.
