With a goal of extending working hours during the war years, the need for better and more efficient light sources became obvious. As early as 1930s, there were significant efforts to improve lighting options in business locations. Commercial hanging fluorescent light fixtures are more expensive to install, thanks to the ballast, but over time, the cost is offset by lower operating expenses. The hanging fixtures are definitely functional, but they can also be attractive and provide a pleasing illumination.
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.
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.
Often, the hanging fixtures are beautified by using a decorative translucent or opaque cover. Light is further diffused and shadows eliminated. Various shapes and sizes of bulbs have been created in order to fill specific needs. Employee work areas can be easily illuminated and customers need not be troubled.
