Lighting can provide a dramatic and practical impact to any space. A well-designed lighting scheme can change any environment from bright and cheerful to moody and atmospheric. Conversely, the wrong lighting type or quantity can create a harsh, uncomfortable atmosphere. Lighting has two main functions. First, it is utilitarian and primarily meant for vision. Secondly, it creates a certain atmosphere and ambiance to any room. This will depend on the intensity, colour and kind of lighting used. Lighting is available in various types. Natural lighting, which comes from the sun is the most powerful form. Artificial lighting includes incandescent lights, fluorescent lights, LED lights, halogen lights, and more. Each type has its own advantages and disadvantages, as well as cost implications. With the advent of energy-efficient LED lighting, lighting is becoming increasingly popular. LED lighting is affordable, long lasting, and requires very little energy to operate, making it an ideal choice for both residential and commercial uses. Additionally, LED lighting comes in an array of colours and intensities, offering a great deal of flexibility in the lighting design. Finally, it is essential to choose the right lighting for different rooms and purposes. Doing so can significantly improve the atmosphere and general aesthetic of any space. Ultimately, the right lighting can make an immense difference in the design of a home or commercial building.
