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.
The purpose of fluorescent fixtures, just like the other types of bulbs is to provide illumination to working areas or commercial locations. The bulbs and fixtures are attached to chains or cords in order to drop the light source so it is closer to the work areas or customer areas in a factory or commercial establishment respectively. The right kind of illumination makes the products look more appealing. Better lighting reduces eyestrain for workers.
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.
There are three major types of fluorescents. Cold cathodes and hot cathodes are similar. Electroluminescent bulbs are different in many ways, but all three types use phosphors excited by electrons, in order to create illumination.
Of the three main types of fluorescent lights, the hot cathode style is most commonly found. Usually, it consists of a long glass tube containing an inert gas (often argon). The gas is under low pressure. There is an electrode on either side of the tube, made of tungsten. The ballast controls and regulates the AC power input to the electrode. The standard size of the tubes is four feet. The illumination offered is 40 watts. In the past, ballast tended to be magnetic. Today they are usually electronic. Electronic ballast is less costly to produce and requires less material.
The cold cathode lamp is also available. The main difference between it and the hot cathode lamp is the coating on the interior of the lamp. Originally this device was not intended as a light source. It also contains gas. The electrodes are attached to either end of the bulb.
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.
