| Read, Write, & Compute |
| | | Good lighting is crucial when we
read, write or use the computer! It affects eye and muscle fatigue, environmental and personal comfort, quality and detail of what we see and overall sense of well-being. Most lighting produces a yellow to pink tone of light that causes glare, provides insufficient levels of light for seeing and emits various levels of heat that can cause discomfort. People often express the complaint that they need or crave more light! Often people increase glare, stress and discomfort when they add more
light because of the yellowness, glare and heat produced. A key to good and sufficient light is to use light that produces increased "see-abilty". Glare is not usable light by the eyes! Most people can see better during the daylight hours by a window or under a skylight. This occurs because all of the colors of the rainbow or spectrum are in outdoor light and the eye picks up light from each color grouping. Generally people can use less light and see more when they use Total
Spectrum light. It produces more usable light for the eye. Total Spectrum light produces light like natural daylight! It often feels like you are under frosted skylights. Glare is virtually eliminated. Heat levels are minimal compared to incandescent and halogen light. Print, detail and color are sharper and more accurate. Total Spectrum light can be invigorating! |
| | | | | Total Spectrum light is ideal for reading. We are continually reading throughout the day whether it be a good book for leisure, the daily newspaper, mail, work-related documents, etc. At times it seems never ending and our eyes are tired and strained. Most reading material is printed on white paper which reflects glare from lights. Total Spectrum light is absorbed by the paper allowing you to
focus on the actual print or pictures. Some newspapers and paperback books are printed on recycled paper which may appear dingy, grey or brownish. Print can seem hazy and blend in with the background. Often the haze is a result of the glare from lighting. |
|
| | | People who use Total Spectrum light have reported that reading the newspaper is easier because the haze is gone and the print seems to be more distinctive and separate from the background.Total Spectrum light is an invaluable tool for students, young or old, to use when studying, reading textbooks or writing reports!

| | | Often the shadow of our hand or body darkens our writing surface
and interferes with seeing what we write. Total Spectrum light is color balanced to daylight and produces a softer shadow than regular light. Regular light is glary and often produces a sharper shadow. Total Spectrum light produces less heat than most lights. This enables the light or lamp to be used closer to the writing surface so that shadows can be reduced or eliminated. An ideal set up for positioning light for writing would be as follows: - Position the lamp in
front of the writing area so that hand shadows will occur under the hand and not affect the writing surface. If you are right handed, position the lamp to the left of the writing surface. The hand shadow will appear either under your hand or to the right of the hand.
or
If you are left handed, position the lamp to the right of the writing surface.
- Position the lamp so that the light output is below your eyes. This can eliminate eye
fatigue because the eyes do not pick up any direct light through the side or peripheral vision. This can also eliminate any body shadows from affecting the writing surface.

Good lighting is essential in providing an environment that reduces stress and fatigue while performing computer tasks. |
| |
| | | The race is on to use computers for work, school, leisure or to access the Internet. Using a computer can be exciting or scary! 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. Ideally there should be no glare or light reflecting off the monitor. The light should be positioned so that (1) there is no body shadow on the screen, (2) hand shadowing on the keyboard does not interfere with seeing the keys and (3) the eyes do do not pick up direct light. Using the guidelines previously listed for writing will help in positioning light. [ Back to top of page ] |
