Lighting is a critical component of any interior design project. Lighting affects the mood of a space as well as affecting the visibility, colour and texture of other design elements. The perfect lighting plan has to be tailored to the specific needs of each space and balanced with natural light. The type of lighting used in a space can range from ambient, task, feature and accent lighting. Ambient lighting is often used to provide a general lighting level, often referred to as general illumination. Task lighting is directed on specific areas and provides visibility for activities such as reading or cooking. Feature lighting can add impact to a room, making a statement or adding to the ambience. Accent lighting, as the name implies, is primarily used to create visual interest and is usually used against walls or ceilings. There are many different types of lighting available today. LEDs are the most energy-efficient option and many varieties can be used for different applications. Halogen lights are widely used and are available in a variety of colours and styles. Incandescent bulbs are still popular and can provide a warm glow in a space. When planning the perfect lighting scheme, it is important to consider the style and tone of the space and how the lighting will be used. Illuminating a space properly can help to create an inviting atmosphere, while the wrong lighting can spoil the entire design. Good lighting design should be an integral part of any interior design project, taking into consideration both function and fashion.
