Illuminate your outdoor living space even in remote areas by placing these stylish wall lights in a sunny spot. This solar light is made from durable plastic and can also be used to provide light sufficient to illuminate walkways and driveways etc. The light has an on/off switch and an integral solar panel. All the lamps in the Intelligent LED Solar Series – are equipped with a self-thinking system- which distributes the stored energy evenly over the number of hours the light is in use. The battery charges up by sunlight that the solar panel captures during daylight hours. The light automatically switches on at dusk and then the intelligent Electronics inside the light detects and calculates the battery capacity and always distributes this energy capacity evenly over an 8-hour period. This means that when the battery has less charge- the light will not be as bright- as it will adapt to the power reserve in the battery. The big advantage of this feature is it guarantees 8 hours of light every night- 365 days a year** Guaranteed- unless the battery will not charge sufficiently due to overcast skies for more than 3 days.. led wall light-external wall light-garden led light
