Lighting is a use of illumination to brighten an area. It serves many functions, ranging from improving the aesthetics of a space to providing visibility in dark environments. Lighting also plays an important role in the psychological effect of an environment, as the atmosphere and mood created by light can influence how comfortable and secure the occupants of the space feel. Indoor lighting is common in all buildings, and it comes in many forms such as LED, fluorescent, natural sunlight, etc. LED lighting is a popular and efficient choice as it is more energy-efficient and lasts longer than other types of lighting. These lights can be used in a variety of ways, such as in room lighting, in ceiling fixtures, and in areas where visibility is required for safety. Outdoor lighting is an important factor for the safety of pedestrians and vehicles. Exterior lighting includes streetlights, parking lot lighting, and landscape lighting, all of which help to make the area more visible at night. Motion activated lights are especially helpful in areas of potential danger, such as dark alleyways and parking lots. Lighting is a crucial component of any environment, be it indoors or outdoors. It can be used to change the look and feel of a space, and to make it more visible in dark environments. With many efficient lighting options available, it is important to select the right kind of light for a space, depending on its purpose and usage.
