Looking for an elegant way to add ambiance to pools, fountains or koi ponds, without the trouble of installing power cables? It's easy with this Floating Solar Accent Light. Just float it in any body of water that has a clear view of the sun, and it will charge by day and glow throughout the night. # Amber floating solar light # Rechargeable Ni-Cd battery # Instructions During the day, the solar panels will convert sunlight into electricity and recharge the included rechargeable battery. In the evening, the Floating Solar Accent Light will turn on automatically. Super-bright LED bulbs provide up to eight hours of light when batteries are fully charged (the hours of light per charge depends on your geographical location, weather conditions and seasonal lighting availability). In addition, a waterproof and impact-resistant translucent polycarbonate light housing shines with an incredible prismatic light effect. Although the Ni-Cd rechargeable battery included with every unit is designed to provide years of reliable use, most rechargeable batteries do begin to deplete after several years. When this happens, the battery can be easily replaced. Replacement batteries are sold separately.
