Using these table lamps is super easy. Just plug the cord into a power outlet and use the on/off switch to turn the lamp on or off. You'll enjoy a warm and cozy glow from the Led A19 9w bulb with 805 lumens. As for maintenance, simply use a soft, dry cloth to wipe the lamp body and the shade regularly to keep them looking clean. Avoid using abrasive cleaners as they might damage the powder - coated metal finish or the resin body. Also, don't place the lamps in direct sunlight for long periods as it could fade the grey color of the lamp body and the white shade. These lamps don't need any assembly, so you can start using them right away. They're a great addition to your home decor, adding a touch of sophistication to any room.
