Is garden lighting costly to maintain? No. The lights are turned on for such a short time the cost of electricity is negligible. Initially the installation of weatherproof lights, wiring, and sockets might seem expensive, but the results of being able to illuminate parts of the garden and its paths at night adds a new appreciation of the garden.
Should lights be directed up to or down on foliage in the garden at night? Both. Varying this direction brings about diversification of interest - a few flowers in bloom by the walk and at another place a spotlight on tree branches from below.
Are garden lights set out permanently in one situation? Not necessarily. The initial installation of underground wiring would include a series of weatherproof plugs so that lights of various types could be changed from place to place as different plants come into bloom.
Are there special lamps for garden lighting? Yes. Your electrical contractors can recommend fixtures of different types and will do the initial installation. A diversified series of lights, illuminating plants to show both flowers and form as well as steps and walks, brings a new enjoyment to the garden at night.
