Prelit Christmas trees are just another way to say pre-lit Christmas trees, which is just to say that the Christmas tree's lights are already on the tree, so you don't have to string 'er up yourself! If you want to spend hours putting up your own lights, stringing them round and around and around your Christmas tree, we won't stand in your way! But if you want a professionally strung pre-lit Christmas tree, ours are the way to go!
