Lighting is essential for almost every aspect of modern life. From the ability to brighten up a room with the simple flip of a switch to providing a source of energy to work and study, humans have used lighting as a key factor in activities and progress throughout history. Early lighting technology such as oil lamps and candles used natural resources such as oil or wax to create light. While this was enough to provide a limited form of illumination, it provided little in terms of energy efficiency. As technology advanced, new form of lighting such as gas lighting and incandescent bulbs were developed which allowed for more efficient light production. Todays lighting technology is based on electricity and is vastly more efficient than early forms of technology. With the advent of LED lighting, energy consumption can be minimized even further in order to create flicker-free and more consistent light quality. LED lights can also provide ambient lighting with adjustable brightness levels. Lighting is used for a variety of purposes, from providing work spaces with task lighting to setting a mood in homes with decorative lighting. It is also used in commercial and industrial settings, where safety is a priority and certain types of lighting are required by law or regulation. No matter what type of lighting is needed, humans have used lighting to help fuel progress and make life better and brighter. The development of LED lighting has allowed for energy savings, while also providing more efficient and consistent sources of light.
