Decorate your outdoor living space even in remote areas by placing these stylish lights in a sunny spot- they will enhance the look and feel of any garden. This solar light is made from durable aluminium and stainless steel and has an on/off switch- it can also be used to provide ambient light sufficient to illuminate paths- borders and driveways etc. All of the lights 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 during daylight hours using free energy from the sun via the integral solar panel. 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 that 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 spike light-garden spike light-garden light
