Create a sense of style and dcor by using these solar powered lights as an accent to your yard, garden, walkway or flower pot. The Sol-Air Solar Powered Violet LED Flower Garden Accent Light comes in a pack of three clear flowers with 22" metal stakes and optional 9" extension rods. They are illuminated by an internal LED light that will turn on at dusk and off at dawn through the use of a photocell. With the included solar panels, these lights operate solely on free energy from the sun, which means no wiring or power adapters are required and no extra utility cost. Simply place them in a desired sunlit area, and the solar panels will absorb power from the sun's light by day and glow softly at night. On average you can expect about six to eight hours of light at night from your violet flower garden accent lights.
