Using the Mehdi Table Lamp is easy. First, screw a 100W bulb with an E26 base into the socket. Then, plug the lamp into an electrical outlet. You can use the 3 - way socket to adjust the light brightness according to your needs. For a cozy atmosphere like a candlelit room, choose the lowest setting. When you need more light for reading, select the highest setting. As for maintenance, keep the lamp away from water to prevent damage. To clean it, use a soft, dry cloth to gently wipe the ceramic base and the shade. Avoid using harsh chemicals as they may damage the finish. If the bulb burns out, simply replace it with a new 100W E26 bulb.
