The light source is concealed within the fixtures and shines light downward in a soft ring, eliminating glare. Lamps ranging from 4 to 20W are appropriate for this application. Fixtures equipped with photocells or dusk sensors are a real convenience, automatically turning the lights on at sunset and off again with the dawn.
Another type of path light is fitted with tough plastic lenses that sit flush with the surface of a walkway. This feature can be particularly handy when you're mowing the grass, as you won't have to trim around protruding light fixtures.
