Cluster lights are strings composed of mini-LEDs (3 mm Ø) very close one to the other, only 1 cm, and slightly distant from the cable. Their structure imitates a full 12 cm Ø garland, which is perfect for example to decorate trees or for hanging. You can choose between the model equipped with a memory controller (7 light effects + steady light) or the one providing only the steady light. Some models with controller are also equipped with 8/16 hours timer, that can be switched off by light button. In this way, the string stays on for 8 hours and then turns off for the next 16 hours.
