Using the Selena Two - Light Metal Table Lamp is easy. First, assemble the lamp following the included instructions. Then, screw in 2 E26 bulbs with a maximum power of 60W or LED equivalents. If you have a dimmer switch, you can install it to adjust the light brightness. To turn the lamp on or off, use the switch on the black power cord. When cleaning the lamp, use a soft, damp cloth. Avoid using harsh chemicals as they may damage the metal finish. Keep the lamp away from water and extreme temperatures to ensure its long - lasting performance. Remember, the bulbs are not included in the set, so you'll need to purchase them separately.
