Description This Solar Post Lights work by using a solar panel to generate energy from sunlight, converting it into an electrical current which charges internal, rechargeable batteries. When switched on, an in-built light sensor controls the lights, automatically activating them once the sensor detects dusk has fallen. The level of battery charge and duration of light time depends on the amount of sunlight received, so these solar post cap lights will stay illuminated for longer during the summer months.
