how long should christmas tree lights be

The length of Christmas tree lights can vary depending on the size of your tree and the amount of lights you wish to use. For a 6 foot tree, you could use 150-300 lights, which should be long enough to cover the tree. For a larger tree, you may need more than 300 lights. It's also important to consider the spacing between lights, as you want the tree to be evenly lit without any dark spots.
