Using your MARDYKE pendant light is easy. First, find a suitable location with a proper electrical connection. Then, attach the pendant light securely to the ceiling. Screw in your favorite filament globe into the E27 socket. When it comes to safety, always make sure the power is off before installing or replacing the globe. Also, keep the light away from water to prevent electrical hazards. For maintenance, simply use a soft, dry cloth to wipe the glass lampshade and the black steel frame regularly. Avoid using harsh chemicals as they may damage the finish. If you have any issues, refer to the instruction manual or contact our customer service. Enjoy your beautiful MARDYKE pendant light!
