Abstract: This dissertation presents the findings of an investigation into whether the power quality produced by the compact fluorescent lamp is satisfactory and the compact fluorescent lamp is accepted by the Hong Kong households. Existing situation is that Compact Fluorescent Lamp (CFL) is not as widely acceptable as they are expected to be. Despite promotion campaigns by the government and manufacturers, incandescent lamps are still widely used in many places, e.g. in domestic premises. Another problem is that most integral CFL with electronic ballast does not have harmonics and power factor control so that CFL may reduce the quality of the power supply by introducing harmonic distortion. Thirteen experiments were executed to investigate the CFLs performance such as the power factor, harmonic distortion, light output and color temperature by using integrating sphere. Data were also collected by means of a questionnaire survey of 223 respondents representing various socio-economic, educational and professional backgrounds in Hong Kong and the results were analysed in terms of an importance index. It was found that the disseminating of energy-efficient technologies, even when they may appear to be technically perfect, is always a tough task, more so in economies with low purchasing power and educational levels. Also, the quality produced by the compact fluorescent lamp is satisfactory. CFL is one such well-known product that consumes only 20% electricity for the same light output as given out by the ubiquitous incandescent lamp and which, if adopted in a wider way, has the potential of reducing peak electric power loads very significantly. Based on the respondent's feedback and experimental results, the author proposes some recommendations to investigate the underlying reasons and to determine the most effective ways in which an efficient technology (CFL) like this could be popularized in Hong Kong households.
