Any source of light that is mounted to a ceiling and hangs down on a rod or chain is known as a pendant light. One of the main features of a pendant light is that it focuses the light from the ceiling and puts it closer to the table or wherever you need it. Thus, outdoor pendant lights are the perfect options for quiet outdoor dinners and cozy sitting areas. Outdoor pendant lights are available in a wide range of sizes and shapes, with the materials used being glass, metal and sometimes concrete. Halogen and fluorescent bulbs are most commonly used in such lanterns.
