Using your Kimli Table Lamp is super easy. First, find a nice spot for it in your room. Then, plug the cord into a power outlet. To turn the lamp on or off, just use the ON - OFF rotary switch. When it comes to bulbs, it comes with an LED A19 9W bulb that gives off 805 lumens of light. If you need to replace the bulb, make sure the lamp is turned off and cooled down. Then, simply unscrew the old bulb and screw in a new one with an E26 screw terminal. As for maintenance, always remember to disconnect the power before cleaning. Use a soft, dry cloth to wipe the lamp and the shade. Avoid using any chemicals or household cleaners as they can damage the lamp's finish. Also, be aware that the lamp contains DEHP and lead, which can cause cancer, and affect development and reproduction. So handle it with care.
