Lighting is one of the most basic elements of interior design. It affects the moods of people, the energy in a space and the overall ambiance. The most important factor to consider when selecting lighting is the purpose of the space. Lighting should be used to enhance the atmosphere of the space and be chosen to accentuate desired features or elements. When deciding on lighting, the first step is to choose the right bulb. Incandescent and fluorescent bulbs are the most common types, but LED lighting is rapidly becoming more popular due to its energy efficiency and long life. Depending on the purpose of the space, choices like dimmer switches may give you the flexibility to adjust the lighting levels for different occasions. Task lighting such as desk or counter lamps are also important elements for many areas in your home. These are typically used to provide additional illumination for specific activities. Wall sconces are a popular option, as they can provide both task and ambient lighting. Chandeliers can be used to create a dramatic effect and give a room a more elegant feel. Natural lighting should also be considered in any room. Skylights, windows and large glass doors are all great sources of natural light. These can be used to brighten up a space without the need for additional lighting. Overall, when selecting lighting for your home or interior space, its important to consider the purpose of the space and the existing fixtures. Consider how the light will be used and if you need additional fixtures. Lighting can be a great way to add atmosphere to a room and transform the look of any space.
