Lighting, the technology of providing artificial light, has existed since the invention of fire. Through advances in light technology, the control of intensity, quality, and type of lighting has broadened our perspective of nighttime. Whether it is on a large scale providing illumination for an entire city, or a small scale lighting up a living room, lighting technology has advanced from its humble beginnings in fire pits to LED lightbulbs, providing people with better, brighter, and longer-lasting light. Lighting has helped us to expand our activities far into the night, creating vibrant cityscapes of illuminated buildings and roadways. On a smaller scale, lighting has enabled us to experience creative expression in our living spaces by enabling us to modify and shape light to change the tone and feel of our nighttime environments. By controlling light, color, and intensity, we can make the light feel inviting and comforting, enabling us to have peaceful evenings at home without needing to depend on the harshness of daylight or the dangers of night. Lighting has become such an integral part of our lives that we have created laws and regulations governing how and when light can be used. For instance, many states have enacted laws limiting lighting within certain areas, exterior lighting can often be limited to night hours, and nighttime lighting in certain areas may have to be reduced during certain periods of time. Lighting has become an important and complex part of our lives and will continue to be so in the future. It is the technology that we use when going out at night, enjoy a bright and beautiful living room or simply to keep safe. And it may just be the technology that will be used to keep us safe and informed in the future.
