As an option of best industrial lighting system the ballasts are being used and this is energy efficient to save more power. The electronic ballast is mainly intended for limiting the consumption of current in the electric circuit. Understanding the ballast factors will help in better usage and appropriate application. The ballast factor for the lighting system is defined as output of light or lumens. When comparing the light output, the ballasts operate lamps at nominal specified rating of power. Some particular factor of the ballasts must be considered while designing the lighting system. This is because the ballast with low factor can help in saving energy considerably but at the same time it will produce only less light.
ballast with fluorescent lamps may function to produce more light compared to test ballast that operates lamp with the line frequency current. This type of ballast will have the factor greater than one. The ballast factor in general is the measurement of output of actual lumen for some specific system of lamp ballast in relative to the rated output of lumen. The ballast factor as such is not the measure of efficiency of power but selecting the specific types will help in minimizing the energy that is used tuning light levels.
