Lighting is a very important part of building design and can drastically change the look, feel and atmosphere of a room. Proper lighting can add a sense of style and sophistication to the overall design while lighting that is too bright or too dull can make a room seem less inviting and less homely. The first step in planning lighting is to consider the purpose of the light. Is it for general ambient lighting, task-based lighting or accent lighting to focus attention onto a particular feature? Your choice of light will depend on the type of space and the overall design goals. General ambient lighting is often best for achieving a uniform and balanced lighting level throughout a room. This type of lighting is commonly used in living rooms, bedrooms and other spaces where a comfortable and inviting atmosphere is desired. Examples can include a combination of ceiling, wall and floor fixtures as well as natural lighting from windows and skylights. Task-based lighting is best for areas where specific tasks are performed such as a kitchen island or working surface. This type of lighting shines directly onto the intended space, and is often adjustable so that the level of brightness can be tailored to the user's needs. Accent lighting works to focus attention onto certain features by making them stand out via bright and well-positioned beams of light. This type of lighting is also good for creating mood and tone, such as highlighting a wall feature with soft, indirect light. When planning lighting, it is important to ensure that the sources used produce the desired level of brightness and color. LED lighting, for instance, is energy-efficient yet produces a bright white light that can be too harsh for certain applications. Similarly, incandescent bulbs can create a soft and warm glow that brings a comforting atmosphere to any room. Finally, all lighting requires careful maintenance and regular cleaning. Dust and oil can collect on fixtures over time and reduce the intensity of light output, resulting in a less desirable overall effect. Taking the time to ensure that your lighting is kept in optimal condition can help improve the perception of the space and achieve your desired aesthetic.
