how many christmas lights for a 7ft tree

7 feet is a good size for a Christmas tree, and the number of lights you'll need will depend on your preferences. A good rule of thumb is to use 100 lights per foot, so for a 7-foot tree, you'll need 700 lights. However, if you're looking for a more subtle look, you could use fewer lights. You could also consider using a mix of different sizes and colors of lights to create a more unique look. Ultimately, it's up to you to decide how many lights you'd like to use for your tree.
