Using your Mater Liuku Ball and Shade Pendant is easy. First, decide whether you want to use it as a single pendant or create a cluster. If using it alone, find a suitable spot in your room, like above a dining table or in a hallway. For clusters, arrange them in a pattern that suits your space. Hang the pendant using the 6.5 ft white textile wire provided. When it comes to the light, it already has a long - life LED built in, but if you need to replace it, use a 1 x MAX 8W LED | GU10. As for maintenance, gently dust the linden wood base with a soft, dry cloth. For the glass shade, you can use a mild glass cleaner and a lint - free cloth. Just be careful not to use abrasive materials that could scratch the glass or the wood. And remember, this item is covered by a 30 - day return policy, so if you're not satisfied, you can return it within that time.
