When possible, opt for full-spectrum lighting, sometimes called "grow lights" in lieu of fluorescent lights. Overhead fluorescent tubes are hard on the eyes and contribute to an overall uninviting environment.
If fluorescent lighting cannot be replaced, enhance the cubicle with accent lighting from a table or floor lamp. It adds to the aesthetics of the cubicle space, while providing more restful lighting.
If a cubicle is near a window, maximize natural daylight by using shorter panels and lighter-colored surfaces. This will increase daylight penetration and unify the output of electric lights that are used.
If possible, incorporate dimmers to electrical lights to allow individual preferences of light levels.
