There are so many things to love about these LED 20M Multicolour Christmas Lights with green Wire. The first is the vibrancy of the colours that will be a welcome part of your home’s holiday decor. The second is the seamless style that easily integrates with any of your green trees, wreaths, or home accents, making the wire connecting the energy-efficient bulbs along each 20-metre strand. Add to this the controller and functionality that is provided, and you are able to set your own program and design your own lighting theme this holiday season. There is an indoor transformer which makes these lights a breeze to operate, although they may be used both inside and out. Furthermore, you won’t have to worry about these lights running up your utility bills during Christmas time due to the pure efficiency of the LED bulbs. What could be easier than that?
