Lighting is an integral part of any environment, both indoor and outdoor. Proper lighting can dramatically change the way a room looks and feels, as well as how its occupants interact with each other. While natural lighting is preferred in many rooms, it is not always possible to rely on it alone. The purpose of lighting is both to provide illumination and to create an aesthetic ambience in a space. Lighting can be used to make an area more inviting, create a sense of safety, and highlight the beauty of certain features. Various lighting fixtures are available, making it possible to customize the illumination of any space. Outdoor lighting is an important component of an attractive landscape design. Appropriate placement of lights can be used to highlight a particular feature in a yard, create ambience, and even deter crime. Outdoor lighting may be more costly than indoor lighting because it requires temperatures that are able to withstand the external elements over the duration of the install. The availability of new, energy-efficient light fixtures have dramatically increased the options when it comes to outdoor lighting. From ambient lighting to task lighting, the right lighting is instrumental in helping create the desired atmosphere and mood in a space. With the variety of light fixtures available and the advances in lighting technology, it is possible to customize the illumination of any space as desired.
