Using this 12 - inch white LED lamp base is a breeze. First, pick a lamp shade that matches your style and use the slip uno shade fitter to attach it to the base. Once the shade is on, simply plug the lamp into a power outlet, and you're ready to enjoy the soft, warm light. As this product is not for commercial use, make sure to use it only in your home. There's no need to worry about assembly, as it comes ready - to - use. Since no assembly is required, there's minimal risk of parts getting lost. When it comes to maintenance, you can use a soft, dry cloth to wipe the base and shade to keep them clean. If the lamp stops working, check the power connection and the bulb.
