Few lighting products offer so much choice when it comes to how you power them. This amazing set of lights can be powered by solar, so in summer months they don\'t cost anything to run, and then when shorter days and longer nights arrive, you have the choice of switching to mains power, to give you year long performance. You can also use these ivy fairy lights as indoor lights when powered by battery or mains power. If you choose to power by battery, there\'s a handy timer function of six hours on, eighteen hours off, which is particularly useful to help save battery life, and making them especially convenient as you don\'t have to manually switch them on and off. Called Ivy, these lights are great to fix to walls, in a climbing pattern, simply secure with cable clips, or U nails, or even cable tie onto trellises. 96 warm white LEDs3 power sources: solar, battery, plug12 branchesIlluminated length: 2.5mTotal length: 5.5mLead length: 3mColour: blackSolar panel: outdoor use onlyLights automatically turn on at dusk and turn off after 6 hoursPlug: outdoor or indoor useBattery: indoor use only4 x AA batteries required (not included)Built-in timer (when using battery mode): 6 hours on, 18 hours off
