Using your Bethel Gold Dimmable LED Table Lamp is a breeze. First, assemble the lamp according to the instructions included in the package. Once assembled, plug it into an electrical outlet. You can adjust the brightness to your liking as it's dimmable. For chair - side reading, set a lower, cozy brightness. When you need to light up the whole room, turn it up. As for maintenance, simply use a soft, dry cloth to wipe the metal frame and crystal accents regularly. This will keep it looking shiny and new. Avoid using harsh chemicals or abrasive materials as they can damage the lamp. Also, make sure to keep it away from water and extreme temperatures. If you have any issues, refer to the UL - listed certification for safety information and contact the manufacturer for support.
