Using these table lamps is a breeze. Just plug them into a power outlet, and you're ready to enjoy the warm, soft light. Since no assembly is needed, you can start using them right away. When it comes to bulbs, the lamps come with two E26/Medium bulbs, but if you need to replace them in the future, just make sure to use the same type. As for maintenance, simply use a soft, dry cloth to gently wipe the crystal base and the fabric shade to keep them clean. Avoid using harsh chemicals or abrasive materials as they could damage the lamp. Remember, these lamps are for home use only, not for commercial settings.
