Lighting is a form of energy. Its the physical manifestation of electricity, without which life as we know it could not exist. With the invention of electric lighting, the world and its inhabitants now have unprecedented access to light, and can use it in a variety of ways. Lighting has enabled us to see and work in low-light conditions, allowing us to be more productive and safe. It also helps create a pleasant atmosphere in our homes, and can be an aesthetic boon for any interior. It can also be used to create special effects, such as in discos and stage shows. Lighting can also serve as an energy-saving measure. By investing in efficient lighting such as LED bulbs or energy-saving fluorescent tubes, people can save money on their electricity bills. In recent years, weve seen a surge in the development of “smart lighting”. Smart lighting can be programmed or controlled by either voice-controlled technology or smartphone apps, and can be adjusted to your individual needs. For example, you can set your lights to come on when you arrive home, or adjust the brightness of the lights in your living room throughout the day. Lighting is an essential component in a wide range of settings, from transport to hospitals to different types of workplaces. Its a form of energy we often take for granted, but one that we could not do without.
