how many feet of christmas lights for 7 foot tree

That depends on how much you want to cover the tree with lights. A standard 7-foot Christmas tree typically requires anywhere from 600 to 1,500 lights, so you'll need to consider how many strands of lights you can handle. You may also want to consider the type of lights you want, as there are various options available such as LED, incandescent, or even fiber optic lights. Whatever you choose, make sure to measure your tree first and plan accordingly to ensure your lights will fit and look good on the tree.
