Abstract
Lighting plays a big part in making a first impression for your establishment and ensuring a comfortable environment. The right light levels will make people feel comfortable. fluorescent lamp are designed to replace an incandescent lamp and can fit in the existing light fixtures formerly used for incandescents. People are accustomed to use fluorescent lamps in their houses recently, for the added benefit of long life and lower total operating costs. Depending on the fluorescent lamp you use, you can save significantly in energy costs as compared to a standard incandescent lamp. These lamps also have considerably less greenhouse emissions than incandescents so they are better for the environment. But if we want to save much more energy, we have to select a suitable ballast that can help the fluorescent lamp to perform best in its life circle. The purpose of this study is to research the influences among different Ballasts (traditional ballasts and electrical ballasts) applied in testing fluorescent lamps and to discuss their performances between the luminous efficiency and color temperature, color-rendering index (CRI), spectrum, power, voltage, current, cost etc. .These informations shall provide how to sellect the best match between ballasts and fluorescent lamps for consumers. Based on this study, the authors recommend that the electrical ballasts are better than traditional ballasts applied to testing fluorescent lamps not only in luminous efficiency but also in electrical efficiency loss. The information can be also an advice to improve for lack of daily energy saving index of Green Building, except that this work can be a frame of reference when the government sets up the relevant polices.
