Illuminate your indoor or outdoor display this Christmas with these decorative cluster lights by Premier Decorations. 720 alternating warm and cool white LEDs over 9.3m lit length and a generous 10m lead from the plug to the first bulb, making them easy to site near a socket. Mains operated with a low voltage UK 3 pin transformer that must be kept dry at all times (have you seen our Dri-boxes?). Cluster lights have multiple lights in close succession to give a stunning garland effect. LEDs are on a green string, making them perfect for draping around most Christmas trees, wreaths and garlands. Controller box makes it easy to set the timer and to choose between 8 light sequences. Available functions; combination, in waves, sequential, slo-glo, chasing/flash, slow fade, twinkle/flash and steady on (static). Non-replaceable LEDs have a longer life span and are more efficient to run compared to halogen bulbs. Includes a deactivatable 8 hour on / 16 hour off timer function, helping to keep energy costs down even further.
