Round, black LED solar lamp Glenios for gardens and driveways This solar light provides a gentle orientation light around the house and is powered by LEDs. An external power source is not required for operation, as the sunlight that hits the solar panel every day ensures that the light can recharge the batteries again and again. Once they are fully charged, the LED solar lamp can shine for up to 16 hours. The black, round design suits many environments and the ground spike can be inserted into many types of soil, where it will find a firm hold, be it a flower bed, a lawn or a planter. It is particularly effective when several of the solar lights are used in close proximity, creating a sea of light points.
