These bollard style garden lights ooze class and provide a real sense of sophistication to any outdoor space. They insert easily into soft surfaces such as soil and turf, allowing you a full range of installation ideas. The lights are solar powered meaning that they don't require any effort on your behalf to get them glowing at night. The solar panels on top of each unit store energy from the sunshine of the day, and as soon as dusk sets in they convert that energy to light through the 3.5 lumen LED light. These garden lights are fully weatherproof allowing them to be left outside all year round without risk of compromising the quality of the product.
