Light plays an important role in our daily lives, providing us with the energy we need to keep us going and to sustain the environment. Lighting is used to bring illumination to dark areas, providing an extra layer of safety and security, as well as increasing visibility in night-time environments. Lighting can be natural, such as the sun and stars, or artificial, such as torches, lamps and electric lights. Natural lighting has its uses, such as providing warmth and illumination to an area, but it can also create shadows and create further hazards in some situations. Artificial lights on the other hand provide targeted and consistent illumination, making them the go-to in many public and commercial spaces. Artificial lighting technologies have come a long way, with a wide range of options available. LED lighting is proving to be a popular choice in modern environments, due to its energy efficiency, low maintenance costs and long life-spans. LED lights also produce little heat and can be used in places where other bulb types may not be suitable, such as outside lights due to their waterproof design. As technology continues to evolve, so do the ways in which we use lighting. Smart lighting is becoming increasingly popular, particularly within the residential market, with products such as wireless switches, dimmers, remote control light sequences and voice-activated controls. Smart lighting allows users to customize their home lighting to suit their individual preferences and needs. It is clear that lighting plays an important role in our day-to-day lives, providing illumination and comfort to us. With the array of different types and technologies available, there is something suitable for any application.
