This set of 12 traditional, energy-efficient, solar-powered lights hang gently from 2 curved shepherd hooks. Each 3.2-volt light comes with a rechargeable AA Ni-MH battery, so these lights are easy to install and do not require any electrical wiring. These stylish solar lights are sure to be long-lasting and are made from durable iron. These lights are energy efficient, running off only the power of the sun. When the solar panel located on top of the light is fully charged, the warm white LED lights stay illuminated for up to 8 hours.
