Watching a monitor can be very fatiguing due to the cycling of the screen. Seeing the location of the letters on the keyboard can be exasperating because many people use the hunt and peck method. Copying or doing data entry can be difficult if there is insufficient or glary lighting. Overhead lighting in offices is often produced by cool white fluorescent tubes. Cool white light produces a lot of glare because of the color balance of the light.
Glare can create headaches plus eye and body fatigue.
The flickering or humming of the ballasts in the tube fixtures can also cause body stress. Using Total Spectrum tubes can greatly improve the quality of light by enhancing visual acuity and virtually eliminating glare. Replacing the magnetic ballast with an electronic ballast can eliminate the flickering and noise associated with fluorescent tube fixtures. Electronic ballasts can also produce energy savings which can results in dollar savings. Using task lighting when doing computer work can be tricky.
