Lighting can be divided into two categories: natural lighting and artificial lighting. Natural lighting comes from the sun or moon and can also be used in buildings and outdoor spaces. It provides bright, soft, and indirect illumination and is excellent for overall lighting for the space. It can also reduce energy costs because it does not require additional power sources. Artificial lighting, on the other hand, is produced by electrical lighting devices. It can provide several different lighting effects, such as low and medium intensity lighting, uplighting, and spot lighting. Artificial lighting can also be used indoors to increase the overall visibility of a room or for accent or task lighting. No matter which type of lighting is used, the goal is the same: to create the ideal environment for a particular purpose. Lighting can be used to create a dramatic effect, emphasize texture, or evoke emotion. Lighting also plays a role in safety and security. Proper lighting in indoor and outdoor spaces can help to ward off criminals, as well as prevent accidents caused by poor visibility. Lastly, it is important to select the appropriate lighting fixtures for the space. The lighting fixtures must be able to provide the desired level of illumination, as well as be able to stand up to the elements if they are to be used outdoors. Technology has improved the look and efficiency of lighting fixtures, while also making them more cost effective. Lighting is an essential part of creating the desired atmosphere in any space. Whether it be natural or artificial lighting, it is important to take the time to select the appropriate type and style of lighting fixtures.
