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.
There are several benefits attained by using the lamps. They are the most energy efficient source for interior lights. The tubes are produced inexpensively, although the ballasts are not cheap. The lighting tubes have a very long life and there is a good choice of colors which are produced. These colors are in a range from cool white to warm white. The production of the light is diffused, making the lamps best for general, even lighting. There are no harsh shadows.
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.
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 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.
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.
