Christmas outdoor lighting can get out of control sometimes. Save a buck on your electricity bill and do something good for the nature with those solar powered Christmas lights.
Unlike standard outdoor holiday lights that must be tethered to an electric source, these solar powered lights can be strung anywhere in your yard. A small solar panel stakes into the ground up to 7′ away from the light strand and powers 102 bright LEDs for up to nine hours after an eight-hour charge. Seven different light patterns dance along the strand in succession, or you can select your favorite sequence to flash continuously or have the lights provide steady illumination with the touch of a button. The solar panel gathers moderate or direct sunlight during the daytime and automatically turns the lights on at dusk and off at dawn. The 32′ 9"-long strand provides enough slack to adorn trees, railings, or lampposts. The LEDs are rated for 10,000 hours of operation.
