Do I need power adapter or Fiber Optic Base for my Christmas tree. How can I tell?

To determine if you need a power adapter or a fiber optic base for your Christmas tree, check the tree's specifications or packaging. If it has fiber optic lights, it usually comes with a built-in base that contains the light source. If it requires external power, it will have a plug and may need a power adapter. Inspect the connections and any included instructions for clarity.
