Lamps are the most adaptable and flexible form of decorative lighting, offering illumination at levels more comfortable for reading. Whether in torchiere, floor or table format, lamps can often illuminate for less labor and money than installed forms of lighting such as recessed or track lighting. As with pendant fixtures, lamps also offer the opportunity to introduce art into a space in addition to its inherent functional qualities. Many lamps have originated from sculpture, vases or other decorative objects that have been adapted over time, making attractive additions, even when not lit.
