Abstract: A tree lighting system for quickly installing lights on a tree. The system includes a tree lighting assembly wherein the tree lighting assembly includes a tiered, cone-shaped net extending between a first ring and a second ring. The net supports a plurality of lights thereon, whereby the diameter of the second ring is larger than that of the first ring. This allows the tree lighting assembly to have a hollow interior volume when the net is expanded into its conical shape. The tree lighting assembly is placed over a tree, whereby the body of the tree is disposed within the interior volume of the tree lighting assembly.
