Fluorescent light is perfectly safe for your eyes. Sometimes very old fluorescent fixtures or a malfunctioning fixture may cause the fluorescent bulb to produce a noticeable flicker. This flicker may be annoying, but it does not cause harm to your eyes.
We have a network of distributors and dealers nationwide that will be more than happy to answer questions about our product. Simply call our toll free number (800-345-9103) and ask for the dealer in your area or visit our online store.
When mounted on a caster floor stand, the fixtures can be rolled very easily within a room or between rooms. If one wanted to use a clamp-on model in two locations, an easy solution is to get an extra clamp for the second location. The lamp can then be carried between the two locations and set in the clamp base attached to the table or desk. Finally, the desk base option allows the lamp to be free standing; however, it is too heavy to carry on a frequent basis (about 27 lbs.).
Bulbs may be purchased through the Dazor online store, but most of the bulbs can be purchased at hardware stores, home centers, discount stores, or lighting centers in your area.
Yes, the fluorescent bulbs come in cool white, daylight, warm white, black light, and full spectrum. See tubes & bulbs.
Full spectrum lighting replicates natural sunlight. This is used for correct color perception where it is imperative to match colors. Proponents of full spectrum lighting say that it reduces glare, increases productivity, operates cooler, and may increase feelings of well being due to the simulation of natural daylight. It is important to note that while some companies market their products as being "full spectrum" lamps, almost any flourescent lamp can become a "full spectrum" lamp by simply using a full spectrum tube or bulb. Dazor offers full spectrum bulbs for use in many of our fixtures, including the magnifiers.
A 13-watt compact fluorescent has comparable light output to a 60-watt incandescent bulb.
An 18-watt compact fluorescent has comparable light output to a 75-watt incandescent bulb.
Fluorescent bulbs operate cooler, use less energy, and last about 5 times longer.
Our ability to see depends upon two factors: (1) proper functioning and focusing of our eyes and, (2) the amount and quality of the light that is reflected from the object back into our eyes. The poorer the lighting, the less light will be reflected from the object back into our eyes. We can't see in the dark - but as the amount and quality of light improves, the better we can see.
In most cases a table lamp with a soft shade is not suited for doing tasks that require seeing small details, such as reading or cross-stitch. Table lamps are designed to look pretty with your furniture and give a soft, warm glow. The shade diffuses the light and prevents more intense, focused light from reaching your task.
Ceiling Fixtures are designed to give overall illumination to a room. By the time the light travels the distance from the ceiling fixture to table level, it becomes unfocused and too dim for seeing small details. Putting brighter, higher wattage lamps in the ceiling fixtures is not an economical solution because it increases your electric bill!
Task lighting refers to any light source designed specifically to direct light onto some "task" performed by a person or machine.
Task lighting can:
Do you realize how much more comfortable task lighting makes our jobs? Have you tried it? A recent study by the American Society of Interior Designers found that poor lighting and eyestrain are the most frequent office worker complaints.
We must be comfortable to maintain productivity over the course of a day. There are enough demands and distractions that compete for our energy and concentration. Straining to see should NOT be one of them. Seeing should be effortless and automatic. We spend a great deal of time and money trying to make ourselves more comfortable so that we can be more efficient and productive. Yet frequently, we neglect a simple and inexpensive solution - a task light.
Personal control. We can adjust the level of light for our individual viewing comfort. Our posture changes during the day. Our tasks vary to some degree. If we have windows, light in the room changes from morning to evening. In response to these changing conditions, we need to be able to adjust the lighting levels directed on our work in order to maintain maximum performance. Task lighting allows us to correctly position the angle of light to eliminate glare and veiling reflections.
Definitely. Magnification is only half of the solution for achieving good vision. Proper lighting is of equal importance. Take an extreme example. How much good would magnification do in the dark? Not much. The benefits derived from visual aids such as magnifiers and prescription glasses are entirely dependent upon the lighting conditions in which they are used. Proper task lighting allows us to get the maximum benefit from a visual aid, and may even allow for reduced magnification. Increasing the amount of light (brightness) directed onto a task will help compensate for small print size or poor contrast. Examples of poor contrast include faded print on white paper, or dark print on a dark background.
Yes. The older we get, the more light we need to see. Research indicates that people in their 60's need 80% more light for reading than people in their 20's. This increased need for light is due to a number of biological facts in the aging process. For example, the muscle in our eye called the iris, expands and contracts to control the amount of light entering our eye. As with all our muscles, the iris loses some of its flexibility in the aging process, and doesn't open as wide. Therefore, more light is needed to compensate for the reduced ability of the iris to open wide.
Instead of trying to maintain proper lighting levels on desktops from overhead fixtures, task lights can do a better job while using less energy. A task light using the new 13-watt compact fluorescent lamp will consume far less energy than a typical overhead lighting fixture. A work environment can maintain lower levels of overhead lighting by illuminating desktops with energy-efficient task lights. In addition, maintenance and bulb replacement costs are less with task lighting.
