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.
As with any other lighting source, the main reason for using fluorescent bulbs is to provide illumination. With large open spaces, the source of the illumination is often this type of lighting fixture. The chains or cords are utilized to bring the fixture closer to the worker or customer's level. Illumination is the best way to make products look attractive and to improve the workspace of employees during night shifts.
Using fluorescent fixtures offers several advantages. The cost of operation is much lower than for incandescent bulbs. The light tubes are inexpensive to produce. Ballast is the component which is more expensive. However, the tubes are long-lived. A range of colors are available, including everything from warm white tones to cool white. Use of the fixtures offers diffused lighting. The illumination is general and even. Unlike incandescent bulbs, there are no shadows created.
Although there are three major categories of fluorescent lamps, they have common characteristics as well. There are similarities in the construction of cold cathode lamps and hot cathode lamps. The third category is that of electroluminescent lamps which are different from the other two. All three styles use phosphors which are activated by electron beams, in order to provide light.
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.
A cold cathode light resembles the hot cathode type, but has an interior coating, making it more suitable to produce free electrons, especially when the voltage is elevated. This type of tube was not considered to be a source of illumination originally. Like the hot cathode, it is contains gas and there is paired electrodes, one on each end.
The third category of lights is called electroluminescent or EL. Alternatively, they are designated high field electroluminescent lamps. In this category of lamps, electrical energy is converted into lighting with no heat. The electrical current is run through phosphor, which illuminates the space. The form of EL bulbs can be produced in various ways.
Adding covers over the fixtures increases the aesthetic appeal. Opaque covers allow for diffusion of the lighting. The tendency for glare or strong shadows is limited. The size and shape of the lamps are fitted to the specific needs in the workplace or commercial space.
