It's not always about having lots of space, just THAT place that's yours. From a nicely appointed home office to a mere closet space, home offices need to show a loving attention to detail and task lighting. A task light usually doesn't have to illuminate the space brightly these days because most writing and reading is done on a computer, but it is still necessary for light reading. Incandescent, halogen, LED - so many choices. The choice depends on personal preference. There is no hard and fast rule which option is the best. Flexibility is a good and so is sufficient lumens output. It is important that the light is positioned so that you don't throw your own shadow onto the reading material.
