How many C9 lights do I need for an outdoor tree?

The number of C9 lights you'll need for an outdoor tree can vary based on the size of the tree, the density of the branches, and your desired level of illumination. Here are some general guidelines to help you estimate the quantity of C9 lights for different tree sizes:

Small Tree (5-6 feet): For a small tree, you might start with one string of C9 lights, which typically comes in lengths of 25 to 50 feet. Consider adding more if you want a denser display.

Medium Tree (7-8 feet): For a medium-sized tree, you may need two to three strings of C9 lights, depending on the fullness of the tree and your preference for a more or less elaborate display.

Large Tree (9 feet or taller): A large tree may require three or more strings of C9 lights. If the tree is exceptionally tall or has a broad canopy, you might need additional strings to ensure adequate coverage.

Keep in mind that it's a good idea to measure the height and width of your tree before purchasing lights. Additionally, consider the spacing between the lights on the string and whether you want a more concentrated or scattered appearance.

It's always better to have a little extra than not enough, so if in doubt, err on the side of getting an additional string. The exact number can also depend on your personal taste and how brightly you want the tree to be illuminated.
