Using these Erin crystal cube table lamps is a breeze. First, you'll need to assemble them as assembly is required. Once assembled, simply plug in the lamp using the 60 - inch cord. Turn the lamp on and off with the rotary switch. The included E26 LED G45 4W bulbs will provide 550 lumens of light. When it comes to maintenance, always remember to disconnect the power before cleaning. Use a soft, dry cloth to wipe the lamp shade and fixture. Avoid using chemicals or household cleaners, as they can damage the finish. These lamps are a great addition to your study, library, or living room, adding a touch of glamour and style.
