Two large ceiling fixtures, containing energy-efficient fluorescent tubes, will provide plenty of well-diffused general lighting, while eliminating shadows on the desk. Place the fixtures over head and to the right and left of the desk so the light comes over the shoulder. Lighting placed in front of a desk will cause troublesome reflections.

Credenzas can be illuminated with slim undercabinet fixtures containing energy-efficient fluorescents. Mount as close to the front of the cabinet as possible to avoid glare reflecting off the work surface.

Pictures, mementos, professional certificates, or an attractive plant can be highlighted with track lighting.
