how many christmas lights for a 7 foot tree

I would suggest using around 300 lights for a 7 foot Christmas tree. This should give it a nice, even coverage without being too overpowering. You may need to adjust the number of lights depending on the size and shape of your tree, but 300 is a good starting point. You can also add some extra lights or ornaments to make it even more festive. Have fun decorating!
