Garland lights are designed for, surprise, surprise - garlands. This string is the perfect length for a 1.2 or 1.8 metre garland. It can also be used on a 2.7m garland however, with the string length very similar to the garland length, the lights sit in the middle of the garland rather than covering the front half of the garland.
If you want to make this string longer you can add up to 4 more strings of lights off one transformer. Therefore you can have a total of 1000 lights on one transformer.
Note: These lights do not come with a transformer. To complete the purchase you also need to choose the straight light adaptor.
