Lighting in a home office

Lighting is a major consideration for laying out a good home office. I set up my work desk beside the window, however at night the light from the overhead light is behind me as I hunch over the writing to edit it.

To cure this I placed a small desk lamp on the desk by the window, and fixed it so that when it is not in use I can set it off the other side of the desk so it is out of the way and not cluttering the desk. It is proving to work good for me so far.
