Using your Mable Marble Table Lamp is easy. First, find a suitable spot in your home. The lamp needs one Type A LED bulb with an E - 26 base, but it's not included, so you'll have to get one on your own. Make sure to use a bulb with a maximum wattage of 9. Once you've inserted the bulb, simply plug the lamp into an electrical outlet and use the in - line switch to turn it on. Regarding safety, since it's UL Listed, you can trust it meets safety standards. However, always keep it away from flammable materials. For maintenance, use a soft, dry cloth to clean the marble base and shade regularly. Avoid using harsh chemicals as they might damage the marble or the fabric. The lamp is not dimmable, so don't try to use it with a dimmer switch. That's all you need to know to enjoy your beautiful Mable Marble Table Lamp for years to come.
