Our bright multi colour solar festoon lights feature 20 LED perspex bulbs. They are solar powered and can withstand rain and wind. Each light bulb is illuminated by a cool white LED inside making these lights the most eco friendly and cost efficient lights you can use to decorate your outdoor areas. Simply position your solar panel in a sun-drenched area of your garden, lawn or roof. There’s a handy ground stake included in the box which just slides on.
