While natural sources of light are usually the most desirable, artificial sources of light can provide the effect needed within a space. Lighting can also add a tasteful flourish to a room, providing a unique feeling of warmness and comfort. Certain lighting techniques may be used throughout a space to provide a tailored effect, for example a spotlight from the ceiling can be used to highlight a sculpture or paintings, or a dimmer light can be used to provide a more cozy atmosphere.
