Hang these pretty string lights almost anywhere you like! Powered by batteries rather than the mains, they don&8217;t need a power source to run. & because they are weather-proof, you can use them in the garden as well as in the house. Supplied as a string of 50 LEDs that stretches out to almost 5 metres long, the fairy lights look magical entwined round the branches of a tree or pot plant, hung from the inside of a parasol, or arranged above a mirror, table or painting indoors.
