Globe string lights are a great way to illuminate your seasonal celebrations, weddings, patios, and indoor/outdoor home decorating. Use these with paper lanterns or alone for a festive ambiance. While they can be used outside, how weather proof they are depends on how well the bulbs are seated in the sockets. They are made with tough, heavy gauge wire, and are designed for installs of up to 90 days. Lanterns and light bulbs sold separately.

Some of these bulbs are torpedo-shaped and some are globe-shaped. Please note that the globe-shaped bulbs will fit better with our Premium Lanterns.
