Using these lamps is super easy. Just plug them into a power outlet and use the 3 - way switch to adjust the light level as you like. You can also use the built - in USB port to charge your phone or other compatible devices. Place them on a side table, nightstand, or any flat surface in your room. They'll add a touch of style and light up your space. When it comes to maintenance, simply use a soft, dry cloth to wipe the lamp base and the shade regularly to keep them clean. Avoid using harsh chemicals or abrasive materials as they might damage the lamp. These lamps are not for commercial use, so make sure to use them in your home only. Also, since no assembly is required, you can start using them right out of the box.
