Lighting has been used since earliest times to illuminate the interior and exterior of various structures and spaces. Today, various kinds of lighting, ranging from electric lights to natural sunlight, are widely used for both residential and industrial purposes. Electric lighting offers a bright, uniform source of illumination with very little heat or noise. It can be incorporated into building interiors, providing clean, indirect light to both windows and walls. Incandescent, halogen and fluorescent lighting are all common types of electric lighting, providing good value for money and several other advantages. LED lighting has seen a rapid increase in its popularity over recent years. LEDs are becoming increasingly popular due to their long life, low energy consumption and instant, bright light. LEDs are also available in a variety of colors, allowing them to be used not only as lights but also as mood-enhancing features. Another form of illumination is natural sunlight. Natural sunlight is particularly suited to spaces with large windows, providing a warm and healthy source of illumination. Additionally, daylight harvesting systems can be installed to control the amount of natural sunlight coming into the space, allowing for an energy efficient and cost effective method of lighting for commercial buildings. Lighting is an essential element in any space, and the right kind of lighting can make all the difference. With the right combination of electric and natural lighting, you can provide a safe, healthy, and aesthetically pleasing environment.
