Fairy lights are charming decorative lights suitable for both indoor and outdoor use. They are commonly seen as special lighting fixtures during holidays and festive occasions, often referred to as "Christmas lights." Since fairy lights are usually sold in strands, they are also known as string lights. However, it's important to note that string lights cover a broad range of designs, so using the term "string lights" isn't entirely precise when specifically referring to fairy lights. In other words, while fairy lights are a type of string light, there are many other variations available. These include festoon globes, lantern string lights, vintage string lights, outdoor string lights, twinkle star lights, and jar string lights.
