The Details About Commercial Hanging Fluorescent Light Fixtures

By Eloise Hewitt


Since the 1930s, the goal of providing longer work hours in commercial and industrial locations has been met, at least in part by the development of larger, brighter and more economical light sources. Commercial hanging fluorescent light fixtures are more costly initially, but the lower operating cost makes them a choice which should be considered by commercial enterprises. Although the hanging fixtures are very utilitarian, they can also be designed in a way that is aesthetically pleasing.

Lighting up a work or commercial space is the major function of bulbs and fixtures. Where there is a large open space, this type of fluorescent fixture allows for light to be spread over a large area. The products which are well lighted appear more attractive. In the workspace, improving lighting allows for shift work without resulting eye strain. The fixtures can be dropped close to the work areas for brighter, shadow-free illumination.

Use of this type of lighting offers a number of advantages. For instance, they are the most energy efficient type when utilized in the interior of a space. They can also be utilized outdoors. The tubes are not expensive to produce. The ballast components are more expensive. Both the bulbs and the ballast are long-lasting. Colors are available in cool to warm white shades. The illumination is diffused, thus eliminating shadows and harsh glare.

Although there are similarities between cold cathode tubes and hot cathode tubes, there are differences as well. In addition to these two major categories of fixtures, there is a third type. Electroluminescent bulbs are different from the other types. All three types operate under the principle of phosphors which are acted upon by electrons.

The hot cathode is the most common type of lamp. It has a glass tube which contain argon, or other inert gas under low pressure. On each side of the tube is a tungsten electrode with a ballast which regulates the power (alternating current) to the electrode. The popular size is four feet in length and emits 40 watts. Ballasts can be either magnetic or electronic, with the electronic type favored today, due to lower production cost and less material needed.

The cold cathode lamp has an interior coating which is more suitable for creating free electrons in conditions with elevated voltage. It was not originally intended as a source of light. The tube is filled with gas and has an electrode on either end.

The third type of lighting is EL (electroluminescent or high field electroluminescent lamps). In this style of fixture, electrical energy is converted into light and no heat is required in the process. Electrical current is transferred directly through phosphor in order to achieve the desired result.

The lamps are made more attractive by adding decorative covers. The covers help to further diffuse the light and remove any glare or strong shadows. Although a long straight bulb is the most common style of lamp, it is being joined by other shapes and lengths in order to meet specific needs in the commercial area. For lower energy usage and functional lighting, the fluorescent lamps represent the best option.
