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.

An adjustable table lamp will provide additional light to the desk and keyboard areas. Position the lamp so it is not reflected in the computer screen.
