Landscape lights come in three general types: pathway lights, up lights, and submersible lights. Like their name suggests, pathway lights look great when placed in an staggered pattern along a path. This type of light shines down, so they can also be used to highlight plants and shrubs. Up lights shine upwards, and are most often used to highlight trees, although they can by used on any tall structures. Submersible lights are used to highlight waterfalls and other water features.
