Lighting or illumination is the deliberate use of light to achieve a practical or aesthetic effect. Lighting includes the use of both artificial light sources like lamps and light fixtures, as well as natural illumination by capturing daylight. Daylighting (using windows, skylights, and light shelves) is sometimes used as the main source of light during daytime in buildings. Types of electric lighting include: Incandescent light bulbs and Halogen lamps. Fluorescent lighting is most energy efficient for offices, shops, factories, warehouses and other commercial settings. LEDs are rapidly replacing fluorescent lighting, with energy savings of up to 90%. Lighting can also be used to enhance the environment of a room or space. For example, incandescent light bulbs, halogen and fluorescent lighting can be used to create a warm, inviting atmosphere with a soft glow. Energy-efficient LEDs may be used to add a modern, eye-catching look to a room or space. Good lighting design considers how a space is used and the occupants needs. It can affect how people feel and interact with each other, as well as how efficient processes are. Proper lighting also affects productivity in offices and shops, safety in roads and other public places, and the enjoyment of art and cultural heritage. Lighting can also be used to achieve aesthetic effects, such as creating theatrical lighting for films, television, and theatre, or sculpting light and shadows in landscapes and architecture. In conclusion, lighting is essential for good human health and safety, as it enables people to see and move around clearly, and it can also be used creatively in both practical and aesthetic ways. It is essential that the right lighting is chosen for different types of applications and considerations are made for the users needs and the environment.
