Using your Cortina Ombre Glass Table Lamps is a breeze. First, find a stable surface in your living room or bedroom to place the lamps. Simply screw in the included Type A light bulb. Flip the switch, and enjoy the soft, diffused light. When it comes to maintenance, remember that these lamps only need spot cleaning. Avoid using harsh chemicals or submerging them in water. If the bulb burns out, just replace it with another Type A bulb. Keep in mind that the lamps are covered by a 2 - year warranty, so if you encounter any issues, don't hesitate to reach out for support.
