• adaptability. Because the fixtures are surfacemounted, ceiling grid patterns and equipment above the ceiling do not constrain the location of fixtures. The fixtures are much easier to relocate when the activities in the space change. (However, elegant and inexpensive electrical connections that simplify moving the fixtures are not yet available as a standard product.)
• low initial cost. The cost of individual fixtures is likely to be lower. Fewer fixtures are likely to be needed. Installation cost may be much lower. Far less difficulty may be encountered in retrofit.
• independence from adjacent lighting. Each task area has totally independent lighting, so it does not matter whether the lighting in adjacent areas is turned on or off. If necessary, glare shielding for the benefit of adjacent areas (discussed below) is easy to instal
