This Set of 12 - Solar String Luminous Glow Lights is among our best looking outdoor lighting products. The set of twelve (12), 2.1-inch (7cm) spheres are made of a durable off-white textured EVA material that looks charming when hung along shrubs, branches, trellises and garden areas. At dusk, the spheres glow warmly with a rich yellowish light that adds elegance to any surroundings. The generous 18-inch spacing between spheres permits the string to cover a 16' distance. There's additional 7.6' length of wire between the solar panel and first sphere to permit locating the solar panel in the best location for optimum sun, using either the ground stake or included building/post attachment kit. The solar panel uses a high quality amorphous type panel and an internal 300mA lithium battery to provide many hours of illumination. Fully waterproof, the panel and spheres look great when placed in trees, along fences or gates, from a trellis or anywhere you're adding atmosphere and elegance to an outdoor space. Powered by the sun, the lamps illuminate automatically at dusk. With good sun exposure, expect 8 hours of illumination or more, as performance is directly related to the amount of sunshine received (summer sun results in the lamps glowing for over 10 or 12 hours).
