Lighting is essential to the modern world and is used in more ways than we can imagine. From small electric lamps that provide light in our homes to giant light towers that help airports safely guide planes in the darkness, lighting is all around us. Lighting also plays an important role in architecture, providing subtle lighting that often enhances the meticulous design of modern structures. In landscaping, lighting can add a dramatic effect when used to highlight plants and other features that are show-stopped when lit at the right angle. In the public sector, lighting is used to deter crime; motion-activated lighting outside of a home can act as a deterrent for burglars and vandals, as well as provide a source of illumination for any visitors. From industrial warehouses to grand cathedrals and museums, lighting plays an important role. It brings an area to life and can be used to emphasize its best features to both visitors and tourists. Lights can also be used to create atmospheres such as romance, merriment, and drama. In the medical field, lighting is invaluable; life-saving operations, surgeries, and administrative tasks must be completed under the right level of illumination to ensure the safety of everyone involved. Lighting is also helping to create a more sustainable future. Through the use of energy-efficient bulbs and solar lighting, we are reducing our carbon footprint and helping the environment by cutting down on the amount of energy we consume. No matter where you look, lighting is a vital part of everyday life; it is a tool that shapes our culture, defines our architecture and helps create a more sustainable future.
