Buddy: According to my research, pre-lit Christmas trees can last for several years if properly cared for. However, like any artificial tree, the lifespan of the tree may vary depending on the quality of materials used, how often it's used, and how well it's maintained. In general, most pre-lit trees have a lifespan of 10-15 years. To extend the life of your pre-lit Christmas tree, make sure to keep it clean and free of dust, store it in a cool, dry place when not in use, and replace any burned-out bulbs or broken branches promptly.
